Fail to wake up from sleep in frame buffer console (Slackware64 14). Sleeps if busy.

Working in frame buffer console causes computer to sleep and not wake-up. Mouse and keyboard can't wake system and computer sleeps while working (using keyboard and mouse). Playing games such as chocolate doom and dosbox doesn't prevent sleep mode in terminal console; games start running choppy right before entering sleep mode and afterwards continue to run (can still hear sounds but monitor remains off forcing me to hit the power button).

My bios has no sleep timers available only S3 and ACPI modes are enabled (not sure about apm, need to double-check). High precision event timer is disabled.

My only option to stop framebuffer console from entering sleep is to let xserver run and log in to another tty (ctrl+alt+fkey (2-6)).

If I log into xserver, quit xserver, and remain in framebuffer console, system sleeps a lot sooner (takes maybe five minutes only).

A shot in the dark, but would something like:

$ setterm -powersave off

see man setterm for other possibilities.

Also, when experimenting with the xserver, perhaps $ xset -dpms, may accomplish something.

That seems to work.

This might be a bug in one of the Slackware64 14 packages or the kernel. Actually, forgot to mention I'm running an updated kernel (not the stock Slackware 14 kernel). Doh!

Has anyone else experienced this problem (not able to wake machine from framebuffer console sleep) on stock Slackware64 14?
