** Tags added: displayport karmic q45 resolution ** Description changed: Binary package hint: xorg - I'm using a Dell optiplex 760 with an intel i915 chipset. + I'm using a Dell optiplex 760 with an intel Q45 chipset. The problem is that xorg *usually* doesn't recognize the screen so it uses a lower resolution 800x600. The only available resolutions are 640x480 and 800x600. Sometimes however the screen is recognized and the resolution is just fine. I haven't been able to find out under what circumstances this happens... My guess is that EDID information is sometimes detected incorrectly... I've tried rebooting Karmic with the kernel parameter modeset=0 and creating an xorg.conf file through X -configure but it doesn't seem to make any difference. I've also noticed that (when the right resolution is selected) after a couple of hours the screen turns black for 1-2 secs. It does that blinking several times and finally the screen turns off. When I restarted the pc it did the same thing only much faster like 5 mins after booting. - ProblemType: Bug Architecture: amd64 Date: Fri Jan 29 12:53:11 2010 DistroRelease: Ubuntu 9.10 InstallationMedia: Ubuntu 9.10 "Karmic Koala" - Release amd64 (20091027) MachineType: Dell Inc.
