Mods, feel free to move this to a more appropriate place. Posted this under General because it involves both hardware and software and maybe Distro.
I'm using a desktop PC that I built, with PCLinuxOS v.2009.1. There seems to be a conflict with the kernel or ATI driver so that when the system is idle for say, an hour, the screen goes black and will NOT wake up. It flickers, then goes black. Nothing but a reboot will get the system to wake up. I've found some discussion about this in here and elsewhere, but not much in the way of solutions.
FWIW, I login to X from runlevel 3 using "startx". Doesn't matter if I'm in X, or in console, the system goes into suspend and can't wake up.
I've turned off Power Management in KDE. Tried it with and without a screensaver. I've tried various commands involving ACPI in Grub, until the system couldn't even boot anymore.
I've reinstalled 3 times.
I've read about ATI's "Catalyst" or fglrx being incompatible with the 2.6.26+ kernels or GLX or something. I've spent WEEKS trying to find a solution to this.
I'm wondering if I can change something in xorg.conf, or change to a different driver, or go back to an older kernel that worked (2.6.18.8), or just buy a new video card that doesn't have conflicts. That last solution will suck because one of the reasons I bought this mobo is because the video is so good and it "was" supported in Linux.
