Public bug reported:
I have a dual head that used to work in Dapper, Edgy and Feisty. It stopped
working since yesterday's updates. I don't know if it is because of the new
kernel (2.6.20.8, was 2.6.20.6 when it worked), or some other package.
I have an ATI Mobility X600 (on a Dell Latitude D810) and I am using the open
source drivers. This is a dual head setup, not xinerama, ie. I cannot move
windows between screens, I have two KDE panels, two desktop switchers, etc.
What happens is rather strange:
- When I boot the computer into X, my external LCD display is ON (not standby)
but completely black. The mouse cursor doesn't show up. However the display
seems to be detected as I can move the mouse away from the primary screen
(although the cursor does not appear). Xrandr detects the correct modes of my
monitor, with 1280x1024 as the default (and selected) mode. I tried to lower
the resolution to 800x600, which causes the screen to "flash", but still
nothing displayed.
- When I suspend/resume the computer, the external screen works, but at 800x600
and xrandr does not detect any higher-resolution mode.
Here are some relevant parts of the Xorg.0.log (I'm also attaching the full
log).
Note that I also tried with MergedFB "off".
