I’ve always seemed to have more trouble setting up monitors and displays under Linux than should be warranted. Cobbling together a few forum posts from Google, here’s what I’ve come up with in xorg.conf that seems to have my VX2025wm working at native 1680×1050@60Hz resolution. You may not need the ModeLine parameter, depending on how your monitor is hooked up – mine runs through a KVM box that doesn’t much like passing resolutions > 1280×1024. Get the changes and xorg.conf after the jump…

You can also directly download the xorg.conf file that I’m using, if you’d prefer to just replace yours. This version is January 23, 2007.
