Public bug reported:
After upgrading to Ubuntu Hardy there are more problems with video card than
previously. I have plenty errors in dmesg:

Additionally monitor sometimes with no particular reason turns off saying that
incorrect mode settings are being used. Switching to console and back to X
"resolves" the problem.
Additionally programs like glxgears or glxinfo segfault on exit.
