Xorg freeze after GL screensaver has been active a while

[Snoopen]

Binary package hint: xorg

When ever I have the computer idle for a while with the screen saver active X will restart and dmesg will display an error about GPU hang. I'm using the GLMatrix screen saver so I'm guessing the problem is GL related.

Snoopen, thank you for reporting this and helping make Ubuntu better.

As per https://wiki.ubuntu.com/Releases, Lucid Desktop reached EOL on May 9, 2013.

Is this reproducible on a supported release?
