I too am still experiencing this bug after the latest kernel updates. Two things I've discovered about this bug:
1) Reverting back to version 169.04 (or earlier) of the nVidia drivers "fixes" the problem. The problem seems to present itself in every version later than 169.04 with Hardy. 2) Installing xserver-xgl gets rid of the problem. I consider both of the above actions to be work-arounds, as opposed to fixes. The newest drivers definitely have noticeable performance gains over the 169.04 drivers. installing xserver-xgl makes X crash for me when trying to run glxgears with the following message in /var/log/messages: May 27 11:25:19 usagi kernel: [ 254.600717] Xgl[7547]: segfault at 00000cf8 eip b7a97b0a esp bf8ed700 error 4 My thought is that there might be a regression in the nvidia drivers, since the problem disappears with the older drivers. But I'm not a developer, so...
