Title:
[Legacy Radeon cards] Desktop effects/compiz: display brightness
fluctuation with zoom, workspace switch or Expo
Status in X.org XServer - ATI gfx chipset driver:
Invalid
Status in “xserver-xorg-video-ati” package in Ubuntu:
Fix Released
Bug description:
Ubuntu Lucid Lynx, kernel 2.6.32.xx
Zooming in with Super+Scroll causes the screen to become very dark,
practically unreadable. Adjusting Fn+Brightness doesn't fix this,
although I can tell the brightness changing slightly. The same thing
happens when changing workspaces (Ctrl+Alt+-> or Ctrl+Alt+<-),
dragging a window from one workspace to another, or using Expo
(Super+E) to view all workspaces simultaneously. Returning to normal
zoom level will always restore the correct level of brightness
immediately, corresponding to how it might have been adjusted during
black out. I also noticed that the cursor will stay bright against the
dark background.
I originally reported this bug against the kernel because with the
mainline kernel there were no issues with brightness (albeit, there
are some other issues). Later it was confirmed to be a bug in video
drivers through the bug report at
https://bugs.freedesktop.org/show_bug.cgi?id=25883
A work around for the bug is to disable the setting 'Lighting' in
Compiz general settings under the display tab.
