Xorg dies due to nvidia (non-free) kernel oops after being left idle for some time

[TJ]

This is the third time I've returned to the PC after leaving it for several hours to find a blank screen lit only
by the flat-panel backlight, looking like the 'blank' screen-saver is operating, but unable to get the PC to
respond when using the keyboard or mouse.

This time I happened to have a notebook that is PXE net-booted alongside and have used it to run an SSH session to
the affected PC.

Looking at the kern.log there are a string of nvidia kernel oops about 2-3 hours after I left the machine.

I'm using "ubuntu-bug -p nvidia-glx-180" to report the bug, via the Lynx text web-browser.

More (stashed) logs will follow once I've restarted the affected PC.

Same thing had occurred again this morning when I returned to the PC. Looking at the log it occured not long after I left the machine the previous evening.

I've posted a new version of the -nvidia driver to our xorg-edgers PPA,
would you mind testing it either on Jaunty or Karmic and see if it
resolves this bug?

Get nvidia-graphics-drivers-180 - 185.18.14 here:

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

I've experienced this on karmic with nvidia-glx-180 (nvidia-185.18.14).
