thank you all gays for your help!
Deate , if i had read your post before installing v2.0 , i wouldn't have! sorry man!
my newbie opinion is that is something with drivers...
pch.shot , u say to enable compiz but set Visual Effects to : none? (because ,low graphic card?)
Deate , the i think the photo u sent reveals the problem
i had not that. in the place u have nvidia , i have ... nothing.
the reference in ati was in a sub menu in the hardware menu!
(my workspaces were locked (one worked)i have 2. 2nd worked if Visual effects were at: none , or normal.)
so , i think that for some reason drivers are not accepted by the OS.(maybe its silly though )
also i have done the installation as u said, + i was uninstall envy. (after reboot , i put it again)
{someone said me that maybe if i give some codes in console will set drivers alive} i dont know
now i have v2,0 (its no envy, or i am blind)
