I've found out that while the 'X' is on the screen (i.e. it's loading the login window) if you Ctrl-Alt-F2 to a terminal then the system remains responsive.
If you then Ctrl-Alt-F7 back to the X screen you just get a black screen and can't get to a terminal again, but pressing the power button actually shuts down the computer properly. Don't know if this helps pin-point the issue... I presume it's something to do with the login graphics or something like that? -- GDM crashes after restart https://bugs.launchpad.net/bugs/274630 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
