I've followed a guide to defining and setting custom resolution using xrandr, but it doesn't seem to be working properly. Ubuntu sets it to 1024x768 automatically, but my monitor is 1024x600. The resolution is changed, but it seems to be lined up from the bottom, that is, the top part becomes unused. Here's the image: http://share.pho.to/979eD/ms/original
I'm using eMachines N214 netbook. The issue occurs on every version and environment I've tried: from 12.04 to 15.04, Xfce, Lxde (which is unusable) and Unity.
