Same is the case with me. I have an Acer aspire 3000 and a assembled Pentium 4
machine. Both show the same behaviour. Monitor flickers, display turns off,
and never turns back on. X doesn't always start correctly. I need to do, CTRL_ALT_F2
 and CTRL_ALT_F7 couple of times before I get it working again.
