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

I installed 12.04.

After first login I can see the Ubuntu screen which does not respond as expected. It goes partially black when I press the Super and freezes, and when I press Ctrl+Alt+T keys the terminal does not appear.

I had the same version of Ubuntu on this machine which is a Sony VAIO. Had to reinstall as partition space on tmp was not sufficient.

Now I have 30GB on root ext4, 5GB on swp and another 25GB on ext4.

I do not understand what has caused this issue suddenly.

Edit: On resetting unity I get this message (I pressed Ctrl+Alt+F1 and then entered unity --reset):

(compix:2172):GCong-CRITICAL **: gconf_client_add_dir: addertion

I have sort of the same issue going on. It appears that Unity 3D is not working properly. I have not been able to figure out what the problem is nor how to fix it. There are so many posts on the topic.

Good news is I do have a work around, using Unity 2D. At the login screen, right click the Ubuntu circle thing to the right of your name, click Ubuntu 2D, and login as normal.

Here is what I get when I execute unity --reset

mmorris@ion:~$ unity --reset
