[elrepo] help troubleshooting detection of external monitor

[Denis Leclair]

I have CentOS 6.5 running on an HP EliteBook 840 G1 with kernel-ml. The 
problem is, I'm not getting any detection of the external monitor that I 
have plugged in to the VGA port. I'm not sure where to beging 
troubleshooting this problem and I'm not finding a whole of advice 
online either.

The details of what I get from xrandr as well as other system 
information can be found on this post I added to the CentOS forums: 
https://www.centos.org/forums/viewtopic.php?f=21&t=45930

I would appreciate any advice on things that I should check for or 
additional reading I can do on the topic.

Thanks.
