I've add a second monitor to my desktop system a couple of months ago, and after much searching I was able to actually get it working.
A couple of days ago, we had a brief power flux and when the system came back up the second monitor was at 640x480 resolution.
I eventually found how to reset the resolution.
Yesterday, we had a power outage that lasted a few hours, when I booted the computer back up, the second monitor did not get activated.
Where is the information for setting up two monitors on a system?
And why is it so freaking hard to find a simple answer to a simple question?
