I have done two things and the bug seems to have gone away (but I have to do some more testing in the next few days). I updated to a newer Kernel: sudo add-apt-repository ppa:kernel-ppa/ppa sudo apt-get update I believe it is 2.6.39-1 generic. WARNING: This is more bleeding edge, so if you don't know how to restore to the previous Kernel, don't try it. (During booting, hold the shift key to get to the GRUB menu and choose booting with a previous Kernel. That at least will give you your system back to then back down to the previous kernel).
After doing that, I also updated my NVIDIA drivers using the following repository: sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update If you are going to add x-swat to your sources, it is important to install ppa-purge, also available in the repositories. YOU MUST DOWNGRADE YOUR NVIDIA DRIVER BEFORE MOVING TO A DIFFERENT UBUNTU VERSION, that is why you need ppa-purge. With the newest Kernel and the newest NVIDIA driver (both installed two days ago in my x64 Asus computer) so far I have not experienced any crashes. I hope this helps, but please USE AT YOUR OWN RISK. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/783002 Title: Auto logoff ubuntu 11.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/783002/+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
