Public bug reported:
ubuntu 12.10.
Problem:
Try to shutdown the machine by clicking poweroff button, the system can not
be shuted down. The screen goes black. Keyboard becomes non functional. All led
lights on my laptop and keyboard are still on. I have to long press the
physical power key to force shutdown.
Occur Ratio/Frequency:
Happens randomly. 80% of time.
Workaround:
Ctrl+Alt+F1 --> login the console --> run "sudo shutdown -h now" will 100%
guarantee the system can be shuted down.
NOTE: even run "sudo shutdown -h now" in a terminal under X environment
will not always work.
