Public bug reported:
Running the current Ubuntu 12.04 LTS Beta2 as a live test from dvd (x64)
- default boot settings, nothing changed, I encountered the following
graphics problem:
In X-Window-Mode on the Unity Desktop my screen starts to flicker
continuous at intervals of about 10 seconds!
There are a lot of error messages from drm/nouveau, so it's obviously a
problem with the free graphics driver for nvidia cards, in my case it's
a 'GTX 560 Ti 448 Limited'. See debug output and hardware details
below...
System settings => Displays says my Monitor is unknown and configuration is set
to 1024x768 (4:3).
My LCD Screen (an older Medion 19") normally wants to work at 1280x1024 -
unfortunately I cannot set a higher resolution in that menu... I tried Detect
Display but that does not find or change anything.
My Hardware:
CPU: AMD FX-4100 4x3.60 Ghz
Mainboard: ASRock Extreme3 R2.0, AMD 870, AM3+, Dual Channel DDR3 ATX
RAM: DDR3-1333 8 GB G.Skill DIMM 2x4096
Graphics Adapter PCI-Express: Gainward Nvidia Geforce GTX 560 Ti 448 Cores
Limited Edition, 1280 MB
