Sleeping system

wyvis · 01-16-2002, 10:02 AM

I have this weird problem with my system sleeping.

At night I log out and the system sits at the KDM login screen. When I come back in in the morning my system has frozen and I can't wake it up (tried mouse movements, key presses, ctrl+alt+del, etc).

I presume this has something to do with power management as I just found out it happens when my screensaver is on too.

Anybody got any ideas what might cause this/how to fix it?

I'm running Slackware 8 with kernel 2.4.17.

Thanks.

This is probably something to do with the power management settings on your motherboard.
If you have some idea of what you are doing, go into your systems BIOS (usually press DEL key when booting) and poke around in there. Try turning off all power management options and see if it solves your problem.
(If it does you may be able to turn some back on.)

Hope this is of some help.

Or, alternatively, and seeing as how you must be knowledgable at compiling kernels as you're running 2.4.17... did you enable APM in the kernel config?

Thanks for the advice.

I did enable APM in the kernel config. Is this correct? If I disable it my machine does not power down during system shutdown.

Yeah, disabling that and recompiling would be a sort of voodoo method of trying to correct the problem. Kernel APM works rather well for most machines, but I've had problems with it on various random boards and BIOSs where a previous kernel had no issues. One of them was the freeze you mentioned above. With APM out of the config it worked fine.

I really wish I knew why and how to beat it AND have APM working.
