I started experiencing this a day or two ago. I have a gtx260 and Im running ubuntu 11.04 x64 with nvidia drivers 270.41.06...Im unable to get a backtrace due to the computer locking up tight(cannot ssh in or anything) so I ssh'ed into the machine from a server and ran tail on a few log files and waited for it happen again...here is what it caught up until it completely locked up tight:

I know this because it happened when i was watching some tv via xbmc...the monitor turned blue(as it does when it has no signal) but audio still played for about 10 seconds...then stopped...and that was it. Also...sometimes when it does this the lights on my keyboard start blinking...sometimes they dont. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/733374 Title: X freeze, nvidia-current, Ubuntu 11.04 Maverick GeForce 9600GT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/733374/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
