B. Bogart, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report: apport-collect -p xorg 1423287 Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information. As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful. Thank you for your understanding.

This occurred with all the Nvidia proprietary drivers available through "Restricted Drivers". This only happens on this machine with an old AGP GeForce Series 6 card (6600), and not on the newer machines with series 500 and 700 nvidia pci express cards. After switching to Nouveau everything was fine for a while, no more CPU pegging from Xorg or render glitches. Then I bought a new monitor to replace the old CRT. So I switched from the VGA connector to the DVI-D connector (which I had never used before). Every once and a while the machine will fail to boot and hangs on the console. I've attached the console output when this happens as an image below. Compare the image to the corresponding output when the system boots normally: Feb 16 08:55:22 insitu kernel: [ 8.124786] nouveau [ DRM] DCB conn 03: 0211 Feb 16 08:55:22 insitu kernel: [ 8.124789] nouveau [ DRM] DCB conn 04: 0213 Feb 16 08:55:22 insitu kernel: [ 8.127639] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
