    Can not log out

    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.

    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:

    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.
