I use ubuntu 11.10. I recently installed gnome shell. The problem I'm facing is that i'm not able to restart or shutdown from ubuntu. I clicked on restart or shutdown button and nothing happens. Just nothing.
I even try to login from my unity shell and still the problem persists. Even more funny, when I boot into linux, and seeing the login screen, Still even after clicking on shutdown, I won't happen.
What mistake have I performed?
But I'm able to perform reboot with the command "sudo reboot".
Any assistance please.
Thanks in advance.
