I'm using Ubuntu 12.04. I've been away for a few weeks, and after I've logged in, I've updated my system to the latest updates, as normal.
However, now I can't shut down any more. Every time I try, I end up with the Ubuntu screen frozen. I can only do a hard shut-down/restart. I've looked into the logs, but I am not really sure which one to check. I've run the commands:
sudo apt-get update && sudo apt-get dist-upgrade
but nothing comes up.
It would be nice to see the commands he is running while trying to shut down. I'm pretty sure it's something related to X11, but I can't find it.
Any hints? Maybe which log to check or how to reboot seeing the command line?
cheers.
Edit: I've checked /var/log/kern.log and I've found the following entry at the shut down time:
Sep 29 21:34:01 xxx kernel: Kernel logging (proc) stopped.
Sep 29 21:38:39 xxx kernel: imklog 5.8.6, log source = /proc/kmsg started.
This was clearly the time of a reboot try. From what I've read just now, the first message is clearly the shut-down and second message is the boot. So, no proof of hard-reset. ?! puzzled...
sudo shutdown now
