@ddadap I have 12.04 32bit with a NVIDIA GPU Quadro NVS 290 dual monitor with one large X Screen.
I've experienced this problem since I updated to 12.04, crashes often enough to seriously disturb my work. It might be network activity related, but the crash is in the nvidia driver (both 295.40 and 302.07). Actually it's 2 crash behavior for me; one is when screen totally freeze up but it's still possible connect; the other is when screen goes black and the login screen appears. I think sometimes the nvidia drivers hangs instead of crashes. Attached is gdb backtrace (only one method), maps and nvidia bug report. Reproducable by running running the following site (that measures your broadband): 1. Open http://www.bredbandskollen.se/ in firefox 2. Press "STARTA MÄTNINGEN" 3. If no crash then press "Mät igen" (to the right) and repeat step 2. 4. While doing this scroll up and down in another window. - Firefox will cause crash - Sublime Text 2 causes crash faster (http://www.sublimetext.com/2) It's not necessary to run any browser or any flash content. But crash usually happens for me during scroll. ** Attachment added: "nvidia-bug.tar.bz2" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/973096/+attachment/3237216/+files/nvidia-bug.tar.bz2 -- 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/973096 Title: Nvidia driver causes xorg crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/973096/+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
