The board I'm running on has an LVDS and VGA output. The LVDS is constrained to no more than 1024X768, the VGA can go up to 1680X1050. When I open the screen configuration, the "Unify Outputs" box is checked, and I can't change the VGA resolution above 1024 X 768. So, I uncheck the Unify box, and set the LVDS to disabled (I don't want to use that output). I can then change the VGA to its max resolution. I apply, confirm it's good, and then set it as default.

However, upon rebooting, once again, the "Unify Outputs" box is checked and I'm back to 1024X768. Quite annoying. Any suggestions?

This is what xrandr -q says:

And this is after unchecking the box, disabling LVDS, and setting the VGA to max.
