PC Locks up because no monitor connected

Post by robertjradio » 2013/05/31 00:39:13

I have an install of Centos 5 on an Acer box which has HDMI and VGA which both work.

It has been sent to a remote location where it will run with no monitor which is the one thing not checked before dispatch!

Box boots up to the point where X server gets loaded

[var/log/messages]

May 31 12:01:07 alexi kdm[3482]: X server for display :0 terminated unexpectedly
May 31 12:01:07 alexi kdm[3482]: Display :0 cannot be opened
May 31 12:01:07 alexi kdm[3482]: Unable to fire up local display :0; disabling.

and it seems no screen no speak

[ /var/log/Xorg.0.log]

(EE) intel(0): No valid modes.
(EE) Screen(s) found, but none have a usable configuration


Is there a way of getting around this or do we have to find a monitor and plug it in?

I have command line access which is working fine but of course the program to be run needs the x server

This problem is completely new to me, I have several boxes with no monitor attached which work fine and they run the same OS. This is the only one that has 2 monitor outs.

Is there some sort of config that can be tweaked?
