I am using a Dell GX270 and I have a funny problem. Every time I go home, I am in the habit of turning off the monitor (a vanilla Dell flatscreen on a DIV connection). I have recently installed Slackware 10.1, and every time I do this, I get a kernel panic!

Well, I know that the simplest solution is just not to do it, but having such a limitation it's an uncomfortable idea, you know, like an itch you are told not to scratch. I'd like to solve the problem, also because soon I'm getting a second computer and I'll be using this one as a file server, with the monitor off, or no monitor at all. Any idea?

FYI, the machine is a plain vanilla one, no RAID, no fancy hardware, no external card (just the lot on the motherboard). What additional information might be useful?

That sounds like a most illogical problem to me. So here's something that may or may not be illogical to try. It's the only thing I can think of (being a newbie-to-intermediate user); try temporarily disabling /etc/rc.d/rc.acpi from starting up.

Do you get any other message along with the Kernel Panic?

Another unusual possibility just ocurred to me. Would this happen if you had your monitor off when you turned on your computer and booted with your monitor still turned off? (Since you said you would be using it for a file server).

I know exactly what you mean about those itches though...

Or try swapping monitors. If anything else, you'll have more info that you have now, it sounds like. That is definitely unusual!

Ok, I wanted to double check so I had to wait until I got back to the University.

ACPI is not activated, and so /etc/rc.d/rc.acpi is already non-executable and therefore disabled. APM is active, but even without it (I tried removing the reference to it in the startup files and rebooting) the problem is still there. I will now go and ask for some colleague to swap monitors - let's hope someone agrees!

Another fact that might be connected and possibly useful: I tried rebooting the machine with the usual Control-Alt-Del and it gets to the "Rebooting" message... without rebooting. Weird.

I'll try to reboot the computer with the monitor off and report.
