Comment 22 for bug 1300557

Hurray, the problem just got a little worse!

After the upgrade to kernel 3.19.0-14.14, when I define my monitor's native resolution using xrandr, I get the right *resolution* but still not the right number of *pixels*. So I'm getting (as far as I can see) one logical pixel per physical pixel on the monitor — but the right-hand and lower edges stay black. It's not just the background picture; I can't move the mouse pointer there or make windows extend into it.

However, after changing the resolution in the System Settings UI and then canceling the change, I finally get a full screen in native resolution like I used to with the previous kernel version.
