I believe I am experiencing a similar problem with Ubuntu Dapper and an
Aladdin TNT2 card (on-board) with the "nv" Driver of Xorg. It only
seems to happen for me when DPMS is enabled -- disabling DPMS causes the
problem to go away, but the monitor never goes into power-saving mode,
just sits there with a black screen.
When it does happen, hitting the keyboard and moving the mouse don't
wake the monitor. For a certain amount of time, I'm still able to SSH
into the machine, so I may be able to get the logs and a gdb bt.
I have DPMS disabled now, so the problem won't manifest itself, but I'll
post my xorg.conf now, and Xorg.0.log and a gdb bt later if I can grab them.
