Comment 22 for bug 275308

I don't believe the issue is the Nvidia driver...
Back on #14 guitara said it was working with:
nvidia-glx-185 185.18.36-0ubu NVIDIA binary Xorg driver

I just checked and that's the same driver I am using now with Karmic:
dpkg -l nvidia-glx-185
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Description
+++-==============-==============-============================================
ii nvidia-glx-185 185.18.36-0ubu NVIDIA binary Xorg driver

So something changed in 2.6.31-14-generic kernel that triggered this problem to reappear, as you'll see from #16.
