Sometimes the Ubuntu 10.04 the gui will freeze and the only thing I can do is move the mouse. I can't interact with programs and I can't change to a different virtual desktop. All I can do is press Ctrl-Alt-Fn and go to the terminal screen. From there I delete the lock file and then do "sudo restart gdm" and I can log back in.
What happens to all the programs that were open in the gui after restarting the gdm? Does VMWare Server get affected in any way?
