in the past the Logout in the Main Menu turn Ok, but now i can't logout, i
have to reboot me linux Redhat 6.0 to change to user!!!!
I don't understand the question so I cannot help solve the underlying
issue. However, I think Control-Alt-Backspace will exit X (and in the
graphical run-level 6 it will start back up and ask for a login). I hope
this helps.
