Problem: it shows only the desktop

[Copper Bezel]

(also, alt+f2 is not working. do you know whats wrong?)

Alt+F2 doesn't do anything unless either Unity or the Gnome Panel is running.

Unity is implemented through Compiz, so if you switch to Metacity, it'll naturally disappear. In this case, one of your settings changes seems to have disabled something.

Since you reinstalled Unity, you shouldn't be missing any Compiz parts. Use these commands to restore your Compiz settings and reactivate the Unity plugin:

gconftool-2 --recursive-unset /apps/compiz-1
unity --reset

in the terminal>>


ali@ali-ubuntu11:~$ gconftool-2 --recursive-unset /apps/compiz-1
ali@ali-ubuntu11:~$ unity --reset

then the cursor is just blinking like its waiting for something...


what should i do next?

[Copper Bezel]

Did you reinstall Compiz before trying it? If you followed ajgreeny's original instructions (and it sounded as if you had,) then the problem above sounds like a result of that (not finding compiz-core.)

[aliboy]

yes. i tried to change the given code to make "remove" into "install" then put compiz. then i tried your code.

[Rat2000]

gconftool-2 --recursive-unset /apps/compiz-1
unity --reset

Oh wow thanks this worked for me. I just wanted ALT-TAB to work (which it didn't in my install) and by changing the compiz settings I ended up with no Unity.

That's way too finicky in my opinion.


Edit: Do NOT activate the "Application Switcher" instead of the "Static Application Switcher" in CompizConfig. It may be prettier by Unity doesn't like it at all (at least in my case).

[aliboy]

so i guess only OS re-installation will resolve my problem. is there any other recommendation?

aliboy, please see this troubleshooting guide for anything you haven't tried already:
