I have gdm and gnome on my install. What happens is that if the computer goes to sleep (fans power down), and I try to wake it up (fans etc come on), the display just remains black. Sometimes it does wake up after I mash enough keys but most of the times I have to just restart the machine.

I really want to get this fixed but don’t know how. I’ve seen some threads on this but didn’t find a solution.

Can anyone please help?
