I just installed Slackware version 9 on my laptop. Everything seems to be working just fine, except that if I leave the computer alone for a few minutes, it turns off the screen and I cannot get the screen back on without restarting the computer. It happens in both X Windows and the terminals and even under Gnome when I have a screensaver set to come up. I checked the BIOS to see if that might be causing this, but it was set to powerdown the screen after 20 minutes. I am sure this is some sort of APM issue, but I do not know where the settings are for that. Does anyone have any suggestions?

Go into /etc/rc.d/rc.M and edit out these lines and see if it goes away:

rc.M:if [ -x /usr/sbin/apmd ]; then
rc.M: echo "Starting APM daemon: /usr/sbin/apmd"
rc.M: /usr/sbin/apmd

It really sounds like an apm issue...

that happens to me after 40 minutes and not only screen lights go off too.but in my computer apm is disabled. what can cause this?

Check your BIOS apm settings and try passing "noapm" as a kernel argument when you boot.

On my laptop, I didn't have the apm module loaded, so it probably is not the apm daemon that is doing it. In fact, I just tried disabling both apm and acpi and the screen still turned off. Whether they are both on or off doesn't seem to make a difference in this regard.

It would be nice if I could just reconfigure one of the two of them.

There's an option in /etc/rc.d/rc.M to blank the screen after 15 minutes of inactivity, but that makes for an odd culprit, may want to try that, starting at line 17.

That line was already set to 15 minutes. Just now I tried commenting it out - no change.

Sorry about the delay here, weekend has been taking its tole on my liver. When you changed the rc.M, did you init down to 1 and then back to 3 to get it to re-read rc.M?

No, I did an Alt-Ctrl-Del.
