Question Screen goes blank

I installed SUSE 10 seemingly without any problems. It boots up and I can play games, run programs, etc. But after a while, the screen goes blank and it never comes back. I can move the mouse or beat on the keyboard with no results. One of Infoworld's editors had the same problem on his laptop after installing SUSE 10.

I really want to use this software and get familiar with it, but if I have to reboot every time I use it it's useless. I tried to update the bios, but there aren't any available updates. I also tried turning off everything in Kpowersave (KDE) with the result that it will come back after 15 minutes or so, but not an hour or more. Windows comes back after blanking the screen, even if it stays blank for a day or two, so I know the hardware will do it. How do I get Linux to work the same way?

And welcome to LQ!

Can you please tell us what make & model your computer is? It would be
also beneficial if you could post the output of dmesg from that machine
here. ...

Sounds like a problem with the power management tools. I know on Fedora, when I try to suspend or hibernate, the same thing happens to me. The screen goes blank and the whole machine locks up and won't respond. Unfortunately, power management tools in Linux kinda suck at the moment, so you probably won't have the same suspend/hibernate control you did under Windows. For now, just make sure your screensaver is just normally blanking the screen instead of trying to suspend or hiberate.

In response to tinkster, I got six pages of output from dmesg. I'm reluctant to post the whole thing here and I don't see a way to attach a file. ACPI is disabled and this is the only line about apm:

apm: BIOS version 1.2 Flags 0x03 (Driver version 1.16ac)

Windows obviously has some hardware call that brings everything back. Surely there is some command in linux that will allow the same thing. Or do we have to wait until the distros fix this?

I forgot: my machine is a Gateway PIII-450, circa 1999.
