I have the same symptom, using the nvidia driver (version x86-100.14.09) and feisty (7.04).
I am still able to ssh into the box, and the Xorg was just hung. Killing it keeps me from having to hard boot the whole box, but that's just a workaround, obviously. What other information can I provide? ** Attachment added: "my xorg.conf" http://launchpadlibrarian.net/8100765/xorg.conf -- Feisty freezes upon Logout or Switch user https://bugs.launchpad.net/bugs/118605 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
