I am finding a rather annoying problem with using KDE/Linux (Mandrake 9.1 beta2) in that the monitor acts like it loses the signal from the DVI card and goes into Power Save mode.  This isn't neccesarily bad except I can't wake it back up.  No mouse movements or key presses works.  I have to reboot.  .  .every single time I try and use Linux.  Could anyone point me to potential work arounds or fixes? Thanks.  BTW I have energy saver  and screensaver turned [off] in KDE.
