[SOLVED] Can not log out

meraj21 · 02-26-2013, 07:05 AM

I am using different desktop environment. When I log out from one to log in another, I see the new name so I log into that. But now I can not remember the name.
Now I can not log out from the environment. And can not do other things. Mouse works, but with right click nothing appears.

Present state of my desktop

Only top date bar shows. When I use arrow key in time of restarting those writings show.
Main thing is, I try to install tor browser. And after install I can't run it. So I try to change desktop environment.

I have solved my problem with following process:

Looks like a problem with your X server.

Go to a virtual terminal (ctrl+alt+F1), log in, and then type:

$ ps aux | grep lightdm

You should see a few processes:

Code:

root      1683  0.0  0.8 270708 31228 ?        SLsl 14:11   0:00 lightdm
root      1717  6.3  5.1 506788 188216 tty7    Ss+  14:11  12:03 /usr/bin/X :0 -core -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none
root      3199  0.0  0.1 177188  3976 ?        Sl   14:11   0:00 lightdm --session-child 12 21
user     25868  0.0  0.0  13588   916 pts/2    S+   17:19   0:00 grep lightdm

See the one that starts with /usr/bin/X ? That's the one we are going to kill.

$ sudo kill 1717 #replace 1717 with the number next to your /usr/bin/X process

It should take you back to the login screen, where you can select a different desktop environment/window manager.

Let's know which desktop environments - GNOME, KDE, XFCE...?

Well, you can switch between different desktop environments like:

Move to KDE:

Code:

~$ switchdesk kde

Move to GNOME:

Code:

$ switchdesk gnome

And to load KDE while running GNOME:

Code:

~$ startkde &

If you're in GNOME, then I guess metacity service is not running, hence you cannot use right click. So check and start it:

Code:

~$ ps -aef | grep metacity

If it gives running process, then simply kill that and then restart, as:

Code:

~$ kill <pid>
~$ metacity &
