I have installed Ubuntu 11.04 and tried login. Everything worked fine. Then i installed compiz config settings manager.
and i do not know what i have changed, now i do not see unity launcher when logged into ubuntu. when i login in classic mode i see all panels and tasks, but when logged in unity mode, i do not see any think except the files on desktop.
Thank you
