Ubuntu switches to low-graphics mode when left unattended for some specific time
When I leave my computer and later return, depending on how long I've been away, I find the screen-saver running, the screen turned off, or the computer suspended, i get the error as specified below on a black screen:
The message gives several options. Despite some experimentals, The only solution which I have found is to reboot and everything becomes fine as before.
Ubuntu is running in low-graphics mode.

I have Lucid 10.04.
