Since Ubuntu/Mint 11.04 and every version thereafter when booting I see only artifacts on the screen. I need to blacklist nouveau to boot to the desktop and install nvidia-current. I rather would use nouveau of course. In Ubuntu 12.10 this is the output during boot: [ 68.480329] [drm] nouveau 0000:01:00.0: PGRAPH TLB flush idle timout fail: 0x011fde03 0x00145b4d 0x0000002d 0X0034db40 [ 70.481621] [drm] nouveau 0000:01:00.0: PGRAPH TLB flush idle timout fail: 0x011fde03 0x00145b4d 0x0000002d 0X0034db40 [ 73.482102] [drm] nouveau 0000:01:00.0: failed to idle channel 3. [ 122.606202] [drm] nouveau 0000:01:00.0: failed to idle channel 2. I found that a lot of users with the same grahpical card have the same issue during several releases of ubuntu and linux mint.
