Hotplug puts monitor to sleep

[sl70]

I want to get my Palm M515 working in Linux, but can't seem to get hotplug to function properly. When I start hotplug it puts my monitor to sleep. It doesn't seem to have any other effects. I can log in from outside, reboot or restart X, but nothing (except rebooting, of course) brings the display back up. The log doesn't seem to show anything wrong (but what do I know). Here's what's in the log:

And then at this point if I login from outside and do
/etc/init.d/hotplug status it tells me it's running.
I'm thinking of trying
rc-update add hotplug boot
but I'm afraid I'll never be able to get into the computer again if something goes wrong. Anyone have any ideas?

It looks like an interrupt problem.

Hotplug is telling some peice of hardware (your mobo maybe) that somethings being plugged in, and then something gets confused and thinks its power management.

Try removing ASCPI/APM from your kernel.

Neither ACPI or APM is enabled in my kernel. I was thinking the problem was in the matroxfb part, since it causes my monitor to blink out. How does that sound?

[sl70]

I solved my problem. My hunch was right. When I removed the matroxfb module (why did I put that in there, anyway?) hotplug started up fine. Now all I have to do is wait for gnome-pilot 0.1.66 so I can sync my Palm with evolution.

(Someone mod me up for solving this. )
