Screen goes blank after being idle 4 a long time & then all input devices freeze!
I'm running Linux mdk 9.2 on a gateway 310X. Now, whenever I leave my machine idle for extended periods of time (like 4+ hours), I return to find that the monitor is blank (though it's not in power saving mode) and moving the mouse or keyboard does not bring the screen back. I have to reboot (ctrl-alt-del) and then it shows the shutdown process (where it fails to shutdown the saslauth daemon) and reboots. At first, I thought that apm was suspending the machine and messing it up (apm has been known to do that, I understand), so I got rid of it, but the problem persisted. I looked at /var/log/security and saw that it ran "msec" a lot when idle so I disabled that as well. The problem still persists.
Can anybody tell me which log files I should see to diagnose what's happening. Once I know what's causing this, I can try to fix it.
Thanks in advance,
