** Summary changed: - Blank screen on logoff + [fglrx] Black screen on Logoff, System completely inresponsible
** Description changed: Here is the scenario that in most cases reveals the issue on my desktop, but not in 100% cases. I login (my login is a member of admin group if this matters), do something. Then I switch user and login under some regular user account. Use the desktop for a while. The do logoff. The screen goes black as during a regular logoff but it never shows login prompt. Neither Ctrl+Alt+Backspace, nor Ctrl+Alt+Del work here. The only way out is to reset the machine.
