Fedora Xorg.conf Three Monitors Update

Friday, May 30th, 2014

I have a Fedora system running with 3 monitors and recently did a yum update that did something to make the three monitors not all come back up properly when rebooted.

I have two monitors on DVI and one is VGA, I had to alter my ModeLine entry to get things back to normal, from:

Modeline “1680x1050_60.00″  147.14  1680 1784 1968 2256  1050 1051 1054 1087  -HSync +Vsync

to

ModeLine       “1680×1050″ 119.00 1680 1728 1760 1840 1050 1053 1059 1080

Option       “PreferredMode” “1680×1050″

Now just as a note, the monitor DID come back if I just removed the ModeLine entry all together, but then the VGA screen was a low resolution. Hope this helps someone!
