This is occuring to me since I upgraded to 12.10 beta 1. I thought that it was a problem with the graphics drivers related to having nvidia optimus.
How to log in: When I notice that the mouse button gets changed to an arrow and the login screen isn't shown for one to two seconds (after this time the mouse and keyboard stop responding so this has to be done before that happens) I press alt + ctrl +f1 and log in with my user. Then I restart the gdm with sudo /etc/init.d/gdm restart and the login screen shows up so you can log in normally. I'm using gnome-shell and gdm. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/559930 Title: plymouthd crashed with SIGSEGV in ply_trigger_add_handler() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/559930/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
