As a FURTHER update, switching to the latest beta version of the nvidia driver, 1.0-9742, has cleared up this problem. Video works fine for me again.
For now, the driver can be found at: http://www.nzone.com/object/nzone_downloads_linux_display_x86_1.0-9742.html That version of the driver has a slight typo bug, but here's a link I found explaining how to patch it manually: http://www.nvnews.net/vbulletin/showthread.php?t=79902 -- system crashes when totem plays a file https://launchpad.net/bugs/70760 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
