display panel content meltdown on pygame.display.set_mode

[Quozl]

on XO-1.5, the display stops being driven if resolution is changed by a user program. the content melts down.

the following reproducer demonstrates the symptom:

#!/usr/bin/python
import pygame
pygame.init()
print pygame.display.Info()
pygame.display.set_mode((1024, 768), pygame.FULLSCREEN)
pygame.time.wait(3000) # three seconds
print pygame.display.Info()
pygame.display.quit()
pygame.quit()

the code effectively calls XF86VidModeSwitchToMode().

A workaround is to add this to /etc/X11/xorg.conf:

Section "ServerFlags"
        Option "DisableVidModeExtension"  "True"
EndSection

[Quozl]

Patch proposed for review. Disables video mode switching. Does not solve cause of symptom but has been tested to be a workaround.

http://github.com/downloads/linux4kix/openchrome/xorg-x11-drv-openchrome-0.2.904-6.2.fc11.i586.rpm available for testing ... in conjunction with the removal of xorg.conf prohibition on resolution change.

[Quozl]

xorg.conf already has the prohibition removed, tested resolution change, worked fine. okay to add to build.

Tested in os852, is fixed. Closing.
