Unhappy Unable to "Wake-Up" System

Hi -

First, let me say this is a fantastic group. I've only been working with Linux for a few months but I've been able to get answers to my questions simply by searching this site (which I found a few weeks ago). So, congratulation to you!

I do have an annoying problem that I have not been able to find a previous thread.

After leaving my system idle for some period of time (I'm not sure how long) it will go into - well for lack of any better description - " sleep mode". Moving the mouse, pressing keys, typing passwords will not wake it up. I force a power-down and then re-boot. During the re-boot Linux recognizes the unclean shutdown.

The system is an older IBM PC300GL mini-tower - so, no batteries, not a laptop, should be no power management services. The other operating that I sometimes still use on the box does not have this problem.

I'm running RH 9.0 and this has happened with both gnome and kde. Display power management is not enabled and a password is required to stop the screen saver.

I did have RH 8 installed for a while and did not experience this problem but I can't say for sure that I ever left the system idle long enough. I probably did but I'm just not sure.

Any thoughts?

The system does have ACPI power management features and it is enabled. The display will enter suspend mode after 1 hour of inactivity. It is this suspend mode that I'm not able to "wake-up" when running Redhat 9.0.

I've noticed other posts on this topic so I'll keep looking.
