Disabling power saver in RedHat

RedHat Linux 5
S3 Vinge DX

When leaving my box unatended for several minutes, the power saver functions kick in (inspite of the fact that I have disabled them at the BIOS level).

The S3 has a problem restarting the video services when this happens. If I am running in X I have to Kill X to recover video, if I am under shell I have to reboot the box.

Interestingly enough, this does not happen when using Slackware.

So the question is, how to disable (or configure) Power Management from RedHat Linux.

there should be a DPMS option. No idea how to make this permanent.

Recompile the kernel and take out APM support in "Character Devices".

See the Kernel-HOWTO.

mcdonc,

This was the solution I actualy implemented, just before my motherboard died and it became academic :-)

Post your comment as an answer so that I can grade it.

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.
