Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

This is not happening all the time, but only sometimes, totally random.

When I'm in the middle of some work something totally weird happens. Keyboard suddenly stops working. I can't type, no matter which key I press nothing happens. I can't press Alt + Tab, I can't press Alt + F4, Alt + F2... nothing. Activities button is dead.

Also right click does not work, and something even more annoying, I can click on the 'menu' in the top right corner(the menu pops up), but clicking on 'power-off' or 'suspend' option doesn't do anything.

The only little thing I can do is:

Close the lid of my laptop so it goes to sleep. Than wake it up again. And than it's ok. Everything works. So I guess restarting (or refreshing) gnome-shell fixes the problem.

My specs: Ubuntu 12.04.1 LTS, Gnome3, Dell Studio laptop

When this happens, is anything added to the end of your .xsession-errors file? (in your home directory) –  hnasarat Nov 13 '12 at 0:53
    
My xsession-errors file is full of errors and warnings, but it's impossible to locate stuff from yesterday or even before. pastebin.ca/2251243 –  user568021 Nov 13 '12 at 13:37
    
This question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions on filing a bug report are here. –  Jorge Castro Nov 21 '12 at 23:19
    
Sorry, I don't report bugs any more. Since askubuntu.com/questions/210967/how-to-report-a-system-bug when I was reading all this sh** ("how to report a bug") and got nowhere. I think it's easier to just post a question here and maybe ask "question" on lauchpad. –  user568021 Nov 22 '12 at 11:14
