** Description changed:
Binary package hint: xorg
If I don't use the computer for a while, the monitor goes to standby to
save power. When I later come back I get the login screen because the
previously running session is crashed. However, this is not
reproducible, it seems to happen randomly since upgrading to Lucid.
