Kind of same problem, allmost every time the pc goes idle, or sometime while playing with some littles opengl apps (like the physics simulator phun app)
here is a xorg.log with the bug... When happening while playing with phun, the screen goes black, then gdm tries to start (mouse cursor round with little dots) ** Attachment added: "xorg.log after freeze during phun." http://launchpadlibrarian.net/12814903/Xorg.0.log.old -- X crashes when idle https://bugs.launchpad.net/bugs/160309 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
