Wanted to make some window-behavior settings regarding Alt+Tab
-cycling. Then after wanted to set the default behavior back. Then the entire desktop lost the unity launcher and all window-menu bars. After restart nothing changed.
If I login with an alternative user, unity seems to work fine.
Tried some solution proposals like Compiz crashes using Ubuntu Classic and Unity and then - after failing - I've reinstalled:
sudo apt-get remove compiz
(no changes)
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install unity
(no changes)
sudo install compiz
(no changes)
If sudo metacity --replace
is used. Following error returns:
Window manager error: Unable to open X display
Any suggestions?
FYI - I'm not a proficient user - the uninstall/reinstalls were suggested in different forums.
