AVC touchpads -- 4F configuration jumpy for some users

Reported by: greenfeld Owned by: martin.langhoff
Priority: blocker Milestone:
Component: olpc-utils Version: Development build as of this date
Keywords: Cc: pgf, tonyforster, carrott, sridhar, jvonau, martin.langhoff
Blocked By: Blocking:
Deployments affected: Action Needed: no action
Verified: no


The new settings loaded to an older AVC touchpad in 11.3.1 os25 via /etc/init.d/olpc-configure are causing a few people (erikos, godiard, etc.) to report odd behavior such as the touchpad starting to refuse to respond. We also have seen occasions where we only could move along the horizontal or vertical axis at any given point in time, turning circular movements into rectangular ones.

Although I personally have just seen the latter on rare occasion in an air-conditioned office something may be wrong with the new settings, or missing. I'm trying to reproduce the issue with a 4F touchpad unit & os25 but have not been able to yet.

  • Action Needed changed from diagnose to add to build

yum update will bring down an olpc-utils update with "5F" configuration -- good for all XOs.

On XO-1.75, OS27 will include 5F config, which we need feedback on.

  • Action Needed changed from test in build to no action
  • Resolution set to fixed
  • Status changed from new to closed

I think it is safe to close this ticket since no one is complaining about the new settings.

Tested the latest AVC configuration changes over a few days with various AVC revisions, a few Synaptics touchpads (to make sure nothing breaks), ebook mode, all suspend modes, etc. with 11.3.1 os27.
