You're lucky then - I've googled the issue and it has hit a lot of users from all sorts of distros, it's not specific to gentoo. Usually when the keyboard won't wake up the PC you can use the power button, which didn't work on my machine either. I'm kind of suspecting the PSU now. It's getting worse, and it happens on several kernel versions (even on 3.0.x which I had for about 3 weeks before going to something > 3.2. When I powered up my machine today (after being off all night) X bombed with no screens found. I restarted xdm and it worked... I'm thinking if the PSU is off maybe it's taking a while to warm up to be reliable - my video card uses one of those 6 port extra power plugs. I'll bet after being on for a few minutes it was fine. I hate diagnosing weird & intermittent hardware problems. The PSU in here is way too much for what I've got in here anyway. Come to think of it, I think I have a spare in my closet, although I can't remember the wattage. > >> (which is normally done for you) *and* in /sys/devices.

I've also tried 3.4.5 and 3.4.9, nothing works. Sigh... I'd better figure out a way to rule out the PSU. It's possible the emerge world that I did at the same time I upgraded to 3.3.8 stressed the PSU. Dan
