I know, that this question seems to be too general, but I would appreciate any ideas, which could help me start diagnosis of the problem.
My problem is that sometimes (about 50% of the time) I am unable to shut down the system properly.
I click Shut Down..., the desktop dissapears and a purple screen with Ubuntu logo appears. The same screen that appears when I turn on the system. Only difference is that there is no indication of any action. The dots under the logo, that usually blink in sequence are all still and after no action for a few minutes, I turn on the computer manually.
The computer shows no visible problems, it is a new machine and boots perfectly each time. I am just concerned, that this is not the right way to do things.
Please could you hint me some possible causes?
Recently I got a "Sorry, Ubuntu 12.04 experienced an internal error" message. The executable is:
And the cause is a segmentation fault.
So maybe I should just report the problem and wait it out, right?
