I have the same problem. Started after I updated, the last time I updated was about 3 days ago, so it most likely is something recent.
The last message displayed on the console is: * Shutting down ALSA... [OK] * Stopping virtual private network daemon(s)... * No VPN is running. Checking for running unattended-upgrades: * Asking all remaining processes to terminate... After that everything just freezes, pressing Ctrl-Alt-Del doesn't work. Only thing that will shut down the system is holding the power button for 5 seconds. -- karmic doesn't shut down - goes to blank screen with cursor https://bugs.launchpad.net/bugs/420137 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
