Running Xubuntu 8.10 Intrepid on an Inspiron E1405 with Philips external monitor.
Everything seems fine except I get a black screen after different amounts of time (20 mins, hours) that I CAN'T recover from.
The monitor light is GREEN, so the monitor evidently hasn't gone into sleep mode or anything.
The system hasn't frozen (music keeps playing etc) but moving the mouse and the keyboard don't do anything.
After forced shutdown (holding down the power button) I can boot back in just fine and hope it doesn't happen again.
This happens WHILE typing so it can't have to do with the system being idle.
Thanks for any help!
