#8702 Go misses turn if made early in collaboration other-activity 9.1.0-cancelled defect 09/27/08

Go (v.5), running on two laptops with build 8.2-764, has a race condition. These laptops were registered with a school server, and connected using a WiFi AP.

One laptop started the Go activity, and shared with the neighborhood. Another laptop joined the activity. After the opponent joined the activity, but before they had finished changing the resolution of the board (down to 13x13), the first player made a move. This move was never seen by the opponent, causing a deadlock.

#6657 gcompris icons in wrong place? gcompris-activities defect 03/07/08

There is a GCompris icon in the activity subdirectory fo each GCompris activity: always the same one: activity-gcompris.svg. There is also a unique svg file in the root directory for each activity. Ideally (1) the icon in the root directory could be swapped in for the common icon so that the activities are distinguishable on the Framw without a rollover. Also, (2) the icons are not "Sugarized" in the sense that they are not grabbing the XO colors; also (3) they often use line elements that are too fine when scaled.

Fixing (1) could be as simple as

cp *.svg activity/activity-gcompris.svg

Fixing (2) is a bit more work. Fixing (3) is a lot of work.

#7138 Updated icons for gcompris activities. gcompris-activities defect 05/30/08

In preparing Peru's 703-based image, I've cleaned up a number of gcompris activity icons. In particular, chess_computer, scalesboard, and suduko. These icons are attached.

You can use the converter in http://dev.laptop.org/git?p=users/cscott/icon-draw-activity to better clean up the remaining gcompris icons to better match the Sugar icon guidelines. Some icons required additional manual cleanup to ensure that they looked okay when the fill color was transparent (as it is in the sugar frame).

#7862 hanoi_real activity fails to launch gcompris-activities 8.2.0 (was Update.2) defect 08/07/08

The hanoi_real activity downloaded from the main gcompris repository fails to launch from the sugar activity list. It does launch from the terminal activity with sugar-launch. Sugar logs report a problem with rainbow. Seems related to ticket #7239, but I'm not sure if disabling security as stated in that ticket is the best route. Also the TuxPaint activity exhibiting a similar behavior is fixed just by changing the activity.info file. See: http://wiki.laptop.org/go/Tux_Paint#Installing_.28Novices.29

#1603 XOrg post-1.3: Built-in fonts being removed from the font path on server reset x window system 8.2.0 (was Update.2) defect 05/30/07

When you run the X server standalone, it quits after initialization because there are no clients left and the server reset clears the builtin font path.

This is a known bug in Xorg's master branch... Nobody seems to be working on it.

Can be worked around by adding -noreset to the serverflags.

#4900 /etc/alsa/asound.state should be in /etc/statetab distro Future Release defect 11/14/07

/sbin/salsa writes directly to /etc/alsa/asound.state, writing through the hardlink and corrupting the pristine copy. In addition, it should be preserved across upgrades. So, /etc/alsa/asound.state should be added to /etc/statetab.

#4996 Journal doesn't load power manager (OHM) 8.2.0 (was Update.2) defect 11/17/07

build Joyride 299 q2d04

The laptop is not plugged in. Choose reboot. The laptop boots to the point where you get the black border around a grey screen, and then just sits there. Then, if you move the mouse, it shows you the full sugar environment, but the journal has not loaded. I believe this is an issue with ohm interfering with boot up. I say this because I tried this twice, yielding the same result. I then did an rpm -e ohm to turn of ohm. Booting then worked fine, and the journal loaded.

#6134 closing lid when suspended in ebook mode has problems. power manager (OHM) 8.2.0 (was Update.2) defect 01/21/08

Q2D09, joyride-1568.

Should cause the machine to wakeup, the screen get turned off, and then the cpu suspend again (immediately).

Instead, the cpu wakes up for 30 seconds, and then suspends.

When you reopen the lid, the machine does not seem to wake up, (power light does not light), and the screen appears to have been left on.

To reproduce:

  1. start the Read activity
  2. let the machine go idle, until it suspends.
  3. close the lid.
  4. observe the power light comes on one full 30 second timeout.
  5. open the lid
  6. note the power light does not light, and the screen appears to be on.

#8584 need "suppress idle-suspend on external power" checkbox power manager (OHM) 9.1.0-cancelled enhancement 09/20/08

our thinking so far has been that in many deployments, external power is as scarce as battery power, and should be conserved in the same way. this clearly isn't true in all cases -- in areas with plentiful reliable wall power (i.e., most G1G1 markets), or even while powering from a vehicle. ohmd should be willing to suppress idle-suspend if we're plugged in.

idle-suspend interferes with normal laptop operation just enough that it's important to allow the user to suppress it. (as an example, idle-suspend interferes with reliable networking. the times when stable networking is desired probably often coincide with the times that stable power is available.)

#4876 OHM suspends while USB HID devices are attached. power manager (OHM) 9.1.0-cancelled defect 11/13/07

It would be nice if USB-HID devices could also wake up the XO.

[18:30] <cjb> c_scott, pascals: when we are in suspend, the USB host controller is powered down. [18:30] <cjb> There's nothing I can do to keep it powered. What I would do instead is refuse to suspend if a USB device is plugged in. [18:30] <cjb> Or, if a particular class of USB device is plugged in -- ethernet, keyboard/mouse. [18:30] <pascals> cjb: That doesn't seem ideal either. [18:30] <c_scott> cjb: right. but i'd argue that 'refusing to suspect if USB hid device is present' is an update.2 feature. [18:31] <c_scott> cjb: *HID* device. that's the particular class you're interested in. [18:31] <pascals> c_scott: network too, I think. [18:31] <c_scott> cjb: i don't see any problem with powering down disk or network (although I may be surprised by reality) [18:31] <pascals> c_scott: network would mean that Chat would fail interestingly [18:32] <c_scott> maybe i should think about the question in the reverse: are there any external USB devices which it would be *safe* to power-down to prolong battery life? [18:32] <cjb> c_scott: you're running an sshd over the ethernet. the machine suspends through idleness. all the ssh clients lose connection. [18:32] <cjb> c_scott: disks. [18:33] <c_scott> cjb: anyway, this discussion should be in trac. pascals, do you have a trac # yet? [18:33] <cjb> I think it may be in Trac [18:33] <cjb> it's certainly been brought up on devel@.

#10160 expose the audio codec's "in use" state to user level kernel Future Release enhancement 05/12/10

for purposes of managing idle-suspend, it would be very convenient to know when the audio device is in use (as opposed to merely "open", status which is already available).

it seems the kernel may already be tracking this, at least for the case of the output device:

<pgf> audio is actually an annoying case.  it turns out it's really easy to tell, from alsa state, whether the input or device is open.
<pgf> unfortunately, all the audio apps open it when they start, and never close it, whether it's in use or not.
<dsd_> the kernel tracks audio codec use and powers it down after 5 secs of inactivity
<dsd_> and this works well, so presumably doesnt face the same problem
<dsd_> i wonder if you can view that state somehow
<cjb> dsd_: yeah, already tried that, doesn't seem to be exposed
<cjb> but would be an easy patch to write, setting and exposing a flag through snd_pcm_playback and snd_pcm_capture.
<cjb> pgf: if you want to file a bug with the interface you'd like, I could work on that
<pgf> oh, that's a good idea.
<pgf> i didn't realize the kernel was already doing that work.
<pgf> so we think the codec is only powered when it's in use (or recently so)?
<dsd_> yeah i think so
<dsd_> but we should also check that its not affected by that same issue with open/close
<pgf> right.
<cjb> pgf: yes, see sound/pci/hda/hda_codec.c; when we stop sending samples, we queue up a power down for CONFIG_SND_HDA_POWER_SAVE_DEFAULT seconds.
<cjb> (=5 for us)

#8043 ship more license translations in olpc-licenses localization Future Release enhancement 08/19/08

Following on from #6928 which says: Let's get the Spanish versions into the release, and then somebody can make a management decision about what other languages to include, and where.

We need to decide which licenses we should ship translations for, and which languages. We will soon be shipping Spanish translations of GPL2, GPL3, LGPL2.1, GFDL alongside the English originals.

Another option is to provide a difference license pack for each deployment, to prevent this growing too large. Or we could have olpc-licenses providing English, and olpc-licenses-es installed on Spanish deployments which provides a few of the translations. And so on...

#5172 Gitweb fails to html-escape "owner" data that it pulls from a user's GECOS field. infrastructure Future Release defect 11/28/07

If you make a user whose GECOS entry contains an email address (e.g. "Joe Schmoe <joe@…>"), gitweb will fail to escape the email address and will produce invalid XML.

The naive solution of calling esc_html($owner) at appropriate points in the code (around lines 3040 and 3400 of our already-patched gitweb.cgi) fails because the $owner variable contains wide chars and the esc_html function does not deal with wide chars.

#8610 Theme music for the XS school server Future Release enhancement 09/23/08

The school server needs to use sound to communicate.

For example, it automatically mounts USB drives and attempts various communications, and this can take some time. Rather than have the human guess how long to wait, the school server should play starting and finishing ditties. It could indicate errors, and give musical progress estimates.

Other ideas would be to have the server play an hourly tune that indicated the disk was 95% full, or play a sad song when the network is in poor shape.

These must be played through the PC speaker -- that annoying thing that beeps at you in the console. It can be induced to play melodies through escape codes. For instance, the following plays an A followed by E followed by a higher A:

  echo -en '\033[10;440]\033[11;250]\007' > /dev/tty1
  # sleep because echo is instantaneous.
  sleep 0.3
  echo -en '\033[10;660]\033[11;250]\007' > /dev/tty1
  sleep 0.3
  echo -en '\033[10;880]\033[11;250]\007' > /dev/tty1
  sleep 0.3

  # silently return the beep to something reasonably normal.
  echo -en '\033[10;750]\033[11;300]' > /dev/tty1

So please, add candidate tunes below, either in this notation or with a script that does the conversion.

#7458 Intermittent lockup during WOL suspend/resume stress not assigned 9.1.0-cancelled defect 07/09/08

Email form cjb:

As a heads up, I've seen a hang on resume (or suspend?) with latest testing. It looks like a scheduling problem in libertas -- dmesg overflows such that I can't see what caused the hang, but that seems to be what the rest of it's trying to say.

Currently trying to reproduce and gather some more data. Javier, we might need some help from your end once we figure out what's happening.

#6010 Export EC wakeup event mask to userspace kernel 8.2.0 (was Update.2) defect 01/14/08

We currently have the "suspend" vs. "sleep" distinction made in userspace, which results in many temporary wakeups in order to see whether we're supposed to be woken up fully by an external event.

Instead, the kernel should expose a method for setting the EC wakeup mask to userspace, and OHM should set it appropriately before each type of suspend.

#9054 Speed up USB resume. kernel 9.1.0-cancelled defect 11/28/08

The largest obstacle to resuming aggressively is the ~800ms that USB resume takes. This bug tracks investigation on how that could be sped up; a first area to look at is Arjan van der Ven's recent patchset to parallelize the (currently serial) 100ms delays for USB ports to come up, so that every port is brought up at the same time.

#9128 2595 suspend causes my hub-attached USB devices to stop functioning kernel 9.1.0-cancelled defect 12/17/08

When I remove '/etc/ohm/inhibit-idle-suspend', the XO eventually suspends (power light pulsing very slowly). When I resume by pressing a key on the XO's (green, builtin) keyboard, power is restored to my attached USB devices. However, while my USB keyboard and my USB ethernet adapter function again (both are plugged directly into the XO), my USB mouse and USB CD-ROM (both are plugged into an USB hub) now do not function. [This is a regression. I do not remember which build still allowed USB-hub-attached devices to function following suspend/resume.]

Took 'olpc-log' dump. With /etc/ohm/inhibit-idle-suspend removed, it took nearly an hour for the dump command to complete (normally it takes several minutes). While the 'olpc-log' command was running, the screen on the XO would dim (as it does for suspend) but would immediately brighten again -- the XO's power light remained lit the whole time (it did not go into slow pulsing as it does for suspend).

#6211 patch for support of per packet mesh ttl wireless 8.2.0 (was Update.2) enhancement 01/25/08

We really need to be able to have applications set the TTL field of the mesh frames they generate. Prime example is being able to generate mDNS frames with TTL of 1 so that they don't get retransmitted by every node in dense environments, effectively saturating the spectrum.

The following patch (by Javier) implements that functionality by adding a sockoption in the driver that the application can use to set the TTL for its traffic.

This patch was originally submitted back in July but it was never incorporated because 1) it uses netfilter to track open sockets and 2) the driver needs to register a new sockoption. Since no other option was suggested and since it is crucial for our scalability, I have asked Javier to update the patch so that it cleanly applies to the current driver (after David's rewrite) and I trust it to Jim that it makes it into our kernel.


#7981 EC mask setting is inefficient kernel 8.2.0 (was Update.2) defect 08/15/08

From rsmith:

So looking my EC logs from the newer joyrides I see that there are like 6 repeat calls for setting up the mask. This is very non-optimal. Without the fastpath EC code you are talking about 100ms or so of EC command time with fastpath its still going to be 25 or 30ms.

Just seems silly to me. Why can we not also have a control that echos a single hex value? Just like the SCSI debugging code.


(Note that this isn't so urgent, because it only affects entering "sleep", and not leaving it. It's still a waste, though.

#2886 some files shouldn't be compressed by jffs2 kernel 8.2.0 (was Update.2) enhancement 08/17/07

Storing a PDF of 35MB takes 25s. to be written to NAND, processor bound.

If this is caused by JFFS2's on-the-fly compression, marking those files as already compressed using chattr or xattr would make these operations much faster.

Also, I presume reading perf would also be improved.

#12606 xo-4 can't record and play sound at the same time kernel 4-software defect 03/07/13

Distance activity start recording audio, play a noise in both machines and finish recording, later process the recording and use the time difference between the noise generated in both xos to calculate the distance.

The xo-4 can't play & record at the same time sound with different ratio or format, then I have modified the Distance activity to have both in format S16_LE, 44Kb, Mono.

Anyway, the record stops when the noise played ends, then is not possible for the activity calculate the distance.

wake with the touchpad or keypress. observe that the wlan LED goes off, then comes back on a bit later.

this is repeatable for me. i realize idle suspend isn't enabled by default, but this feels like a regression to me.

#11968 Possible skb leak in asix/usbnet kernel Future Release defect 06/22/12

I saw page allocation failures upgrading a 512 MB XO-1.75 from 11.3.1 to 12.1.0 os15 while olpc-update was running on 11.3.1.

These occurred when an asix USB ethernet adapter was used with such frequency and were logged against so many things that the XO was unable to upgrade without a reboot using wifi after the asix adapter was removed.

After a reboot the XO was upgraded successfully to 12.1.0 via wifi & the libertas card, which is much slower (only 100-200 KB/sec reliable bandwidth in our area).

Psmem.py did not show unusual memory usage by any userspace process. I have not retried the upgrade with the asix adapter since.

#11877 device permissions for USB devices should be more permissive distro Future Release enhancement 05/21/12

we often need to add non-root access for USB devices -- typically devices used for Lego or other robotics applications.

we should add a udev rule to give rw permissions to everyone, based on some useful criteria: perhaps if no kernel driver has claimed the device, or perhaps simply for all devices that aren't of certain classes (e.g., everything but storage devices).

#11641 yum upgrade fails on kernel rpm due to conflict over /boot/olpc.fth kernel Future Release defect 02/16/12

"file /boot/olpc.fth from install of kernel-<...> conflicts"

Given our current kernel rpm setup, kernels will conflict over /boot/olpc.fth . Using "rpm -Uvh new-kernel.rpm" literally upgrades the rpm package; yum however will install new kernel rpms in parallel, assuming that the rpms have no files in common.

We only hit this when we change olpc.fth, because rpm has the strange property that two packages can own the same file, and only conflict over it if the file contents differ. We seldom change olpc.fth .

One workaround is to run "rpm -U /var/cache/yum/<repo>/packages/new-kernel.rpm", then re-run yum update.

Yum upgrades are not supported at this stage, so this is very low pri.

#11763 gcc segfaults a lot on XO-1.75 12.1.0 distro Future Release defect 04/06/12

Compiling ffmpeg on XO-1.75 with 12.1.0 os6 ends in failure. From a clean install, run the following commands:

sudo yum install -y --nogpgcheck yum-utils gcc make

wget -c http://download1.rpmfusion.org/free/fedora/development/17/SRPMS/ffmpeg-0.8.9-1.fc17.src.rpm

rpm -i ffmpeg-0.8.9-1.fc17.src.rpm

tar -xjf ~/rpmbuild/SOURCES/ffmpeg-0.8.9.tar.bz2
cd ffmpeg-0.8.9

after approximately 20 minutes, it ends with:

libavcodec/ansi.c:162:17: note: ‘width’ was declared here

See <http://bugzilla.redhat.com/bugzilla> for instructions.
The bug is not reproducible, so it is likely a hardware or OS problem.

I managed to capture the gcc command line:

It doesn't always fail but happened on 3 different laptops. If it succeeds, make fails with the same error on a different file. I haven't successfully compiled ffmpeg.

Adding swap doesn't seem to make a difference.

#190 JFFS2 power failure handling kernel Future Release defect 10/18/06

A pathological pattern of power cycles can cause JFFS2 to entirely run out of space to perform garbage collection. For example, hook up an automatic power switch triggered by the NAND controller and make it cut power in the middle of each page write, unless it's the first page in an eraseblock.

Thus, each erase block will have only a _single_ valid node and thus can't be deleted -- but the rest of the space in each block will be wasted by failed write attempts. And then you'll have no free space left into which you can garbage collect, and you see nasty messages like ‘Argh. No free space left for GC’

There are ways to deal with this -- you can reserve an extra eraseblock for "panic" garbage collection, where you don't GC normally, but instead you just _copy_ nodes intact from the least-used eraseblock, just as we copy REF_PRISTINE nodes. If power is interrupted during this 'panic GC', we can erase the target block and try again. If we manage to write the whole thing, then we can erase the _source_ block and it becomes our panic block for the future, while we still have the tail end of the block we've just written which is available to allow normal GC to proceed.

This relies on being able to recover properly after the power failure -- we have to:

  1. Know that we're in panic mode, which is easy enough because there are no free eraseblocks.
  2. Find the block which we were copying into, which is also relatively easy because it contains only nodes which are _duplicates_ of other nodes on the medium, with precisely the same version number. Currently we silently drop one of the duplicates, but we can change that to keep a record so that we can find blocks which are entirely made up of such nodes.

This also helps us deal with the uncertainty around garbage collection, where it was never mathematically proven that we were reserving enough space to allow GC to proceed under all circumstances. The ‘panic mode’ should allow us to avoid getting stuck, as has occasionally been observed to happen.

#3032 JFFS2 performance on content bundles. kernel 8.2.0 (was Update.2) defect 08/26/07

We need to study JFFS2 and overall system performance for content bundles.

Some questions are: should we have large files with lots of content, or multiple small files (which depends on performance of large directories vs. performance of large files). Should we compress the whole file and implement the chattr ioctl interface we've spoken about for so long to tell JFFS2 not to bother? etc.

We need to fix whatever performance issues exist, and give coherent guidelines to those providing content.

Some samples of potential content are at...






[02:17] <Arael5> I could stuff a lot more content into XO if I could use file.html.gz and iso image for storing thousands of small files.

[02:17] <Arael5> I have tried to open 250kB html file on XO and it took 30 seconds to open it on build 406.

[02:17] <Arael5> 100kB html file loaded in 7 seconds.

[02:23] <Arael5> The 1mb file is here http://arael.shtooka.net/fi/html/1mb.html

[02:24] <Arael5> If XO could open it in less than 10 seconds I will not have to use many small files in my bundles.




#5723 Actiontec Router Issues...no Gmail/Google/Wiki wireless Future Release defect 12/27/07


Just received my XO and I've been having difficulty connecting to the web with the browser.

I'm running an actiontec router...had issues even having it show up in the neighborhood view until I switched over from channel 9 to channel 6 per the recommendation of a friend. This effectively made the actiontec router show up in the neighborhood view.

Browser worked intermittantly.

Today I go to log on again and I can get certain websites: http://www.burgerking.com; http://www.mcdonalds.com; http://www.wcnx.org; http://craigslist.org. I can ping google.com and get packets back, 109ms. But if I type google.com or http://www.google.com or http://mail.google.com into the browser it runs incessantly and then I get a network timeout error.

Here are the specs on the WAN/LAN etc from my router, just incase:


WAN Status: Conencted; PPPoE; IP Address:; Subnet Mask; Gateway; DNS 1:; DNS 2:

Lan Status: IP Address:; Net Mask DHCP On.

SSID Broadcast: Enable; 802.11b/g mode: 802.11g only

mac authentication: accept all clients. no exceptions.

wireless on; ESSID: GriffithAp; Channel: 6; Security: Off

Both my ubuntu machine and my olpc show up in the ARP table and the active user list as DHCP connected and IP assigned ( for the OLPC; for ubuntu).

Any ideas as to why this is behaving this way??

#907 Provide a way to run "unsugarized" applications under sugar... distro Opportunity defect 02/20/07

While this is much less desirable than having applications sugarized, we need some way to run unmodified applications that require multiple windows open simultaneously: an example, just to name an application that does this, not that we expect to run it, is the gimp. We need applications to be able to run, even if they don't meet the needs of some kids due to UI complexity.

Ion, for example, provides a way to do this, from talking with Mako. It may be Matchbox needs to do this as well.

#16 voice messaging infrastructure Gen2 task 07/26/06

Since many kids (and family members) won't have continuous contact to the internet, despite our best attempts, having non-realtime voice messaging of some sort would be a great help to many people.

Ideally, the UI for this operate well int he sugar environment, and there are many possible transports for the message. Automatic opportunistic behavior would be very desirable (if you have a message bound for someone, and that person becomes available, taking the opportunity to deliver the message immediately would be very good).

Note that conventional mail systems are not typically very good at this: they queue mail, and only run queues on a periodic basis. This might be quite different, more like "buddy pounce" on IM systems, where a message is forwarded whenever the recipient appears.

Of course, delivery via a school server is another option; a message might arrive on one laptop in the morning and get home to the recipient on another laptop that evening.

#4859 Mesh View: Selecting an AP/mesh icon does not dismiss its palette sugar 9.1.0-cancelled enhancement 11/13/07

If the user want to connect to some AP or Mesh network, he has to click the right icon but the palette of this icon is never hided and that make it feel that nothing happens. As the palette never come's hided the user try to click the palette title :/ .

For buddy icons, all actions are in the palette and for ap/mesh network over the icon, I think this must be fixed.

Here's a patch attached in order to close the palette when the user click the AP, but would be better to handle the 2 ways to connect: clicking the icon and closing the palette and add a 'connect' menu item in the palette.

#5622 Record doesn't save EXIF data record-activity 8.2.0 (was Update.2) enhancement 12/21/07

The Record activity doesn't record EXIF data identifying the XO as the creating entity, nor any exposure info etc.

#6461 increase-mcast-rate needs adjustments distro 8.1.1 (was Update1.1) defect 02/14/08

Two comments on the "/etc/NetworkManager/dispatcher.d/increase-mcast-rate" script

1 - The rates passed to iwpriv must be doubled. The way it is the rates are being fixed at 18Mbps.

2 - Also, using msh0 or eth0 makes no difference. We don't need both iwpriv commands. The command does not affect infra-structure traffic, either way.

So, for clarity sake, I believe what is intended is:

iwpriv msh0 mesh_set_bcastr 72

Or, if the intended rate is 11Mbps:

iwpriv msh0 mesh_set_bcastr 22

We could use a fileserver with some disk redundancy with at least 1TB of usable space, to mirror large collections.

Separately, I have a ~1TB disk image of an eGranary available to schools that wish to use it, which should ideally be mirrored and kept in our colo. Because it takes hours to make a raw disk image (and significantly longer to copy files via rsync), it is useful to reserve a dedicated pair of disks for this.

In Browse, go to a web site and enter mis-spelled words in any textarea (like this page).

The Gecko engine's spell checker underlines "badword" in red, but there's no access to corrections.

I don't know if this is simply lack of a right-button context menu in Browse, or a design issue. Apparently Write has the same issue (bug 5394).

#7401 youtube still too hard to get working browse-activity defect 07/01/08

Playing videos from YouTube (And google video) has long been one of the most frequent requests of XO users... it still takes too many steps to make this work.

These videosites don't work by default with the latest Gnash, and it's still too hard to update Browse to make it so : it requires opening finding the right how-to page or FAQ, opening a Terminal, and downloading & applying the Flash RPM.

While sites such as dailymotion are providing ogg videos for us, we should make it easier to enable the most commonly used sites (and should probably have a list against which to test how well Browse works by default).

#10514 Scrolling using the arrow keys or dpad in Browse browse-activity Future Release defect 12/06/10

- open a pdf in Browse

- the scrolling behavior is inverted (up scrolls down, down scrolls up)

This is because by default the Spinbutton has the focus. And 'up' means here increment the page number (going down) and 'down' means here decrement the page number (going up).

I think the interface is a bit misleading. I think we should use the same interface as Read to be consistent.

#7825 can't complete WPA handshake with D-Link WBR-2310 wireless 8.2.0 (was Update.2) defect 08/05/08

Testing a D-Link WBR-2310 in WPA mode. Authentication completes, association too, but WPA PTK/GTK handshake fails.

There are 4 handshake messages as usual (supplicant, authenticator, supplicant, authenticator) at which point the PTK is installed. It then enters group handshake mode but wpa_supplicant does not see the next EAPOL.

I ran a system in monitor mode next to it and confirmed that the AP did send the 5th EAPOL. It did not retransmit it, suggesting that it also received acknowledgement (my monitor does not show acks). So the message is being lost somewhere.

Interestingly, it is timing-sensitive too. If I run wpa_supplicant in verbose mode on the XO console, the extra delay imposed by printing a lot of messages results in WPA PTK+GTK completing. Odd.

#648 Sugarize "puzzles" collection. sugar Opportunity enhancement 01/02/07

http://www.chiark.greenend.org.uk/~sgtatham/puzzles/ is a fun collection of lightweight GTK2 puzzles written in C, which we could distribute. We'd just need a few changes:

* a sugar activity for choosing between the puzzles * conversion of the drop-down menu items to icons, since we don't want to have to translate the options, and many kids couldn't read them even if we did.

We likely won't have time to do this ourselves for a good while; if anyone's looking for a project to introduce themselves to sugar, this could be a fun one.

Looking further, there is a huge collection of games at http://www.happypenguin.org/... we should take some time to sort through them for good ones.

#11645 Gcompris show artifacts in xo-1.75 x window system 1.75-software defect 02/17/12

Hi, Uruguay is requesting include Gcompris in their new image with the xo-1.75, and testing it, I have found different graphic artifacts. Should be good to know if are driver or libraries issues, and if we can solve them. To test it do:

Download and install http://arm.koji.fedoraproject.org/packages/gcompris/9.5/1.fc14/armv5tel/gcompris-9.5-1.fc14.armv5tel.rpm

Execute gcompris. There are little line artifacts in the main screen, but if you go to "discovering activities" (second icon), maze, and select the second or third maze game, can see the penguin is only displayed when points to the bottom, like if the routine used to rotate the image does not work.

I have tested with or without fullscreen. There are option --cursor to use the standard cursor. These errors do not happen in xo-1.5.

#1859 Add a "Ready" screen in Kuku kuku-activity Opportunity enhancement 06/29/07

The XO's sticky keys, coupled with occasional lag between questions/screens, can make it seem as though the user hasn't selected the answer even after pressing the key, when he actually has...so he'll press it again, and end up pecking twice (once for the correct answer he selected, and once again on the new screen that appeared AFTER he pressed the key, causing him to peck the incorrect answer on the new screen without his even realizing it). This caused me to accidentally pick the wrong answer quite a few times (after victory screens in particular). Maybe making a "Ready!" message on each screen and cause no key presses to do anything until the Ready message has displayed?

This lag is not limited to pecking - moving, and pretty much all commands, are subject to occasional lag that can interfere with gameplay. It would be nice if this was fixed.

#477 Improvement needed in Gamepad Buttons hardware Gen2 enhancement 11/18/06

Hi, Folks,

We're not satisfied with the current gamepad implementation on the B1 units. The problems here are threefold. First, the implementation of the left gamepad controller needs a bit of tweaking to ensure consistency across all units (we currently see a failure rate of ~2.5% on the gamepad switches). Second, the electrical design of the current gamepad buttons should be enhanced for N-Key rollover, which means that it will be possible to depress "many" buttons simultaneously without generating "ghost" / false button triggering. Finally, the EC's scanning logic for the gamepad buttons is currently broken - simple firmware enhancements are required to implement the gamepad scanning logic properly.

All of these features should be implemented in the B2 build.
