Same problem for me: I have ubuntu 13.04 and kde 4.11. I removed my fglrx drivers, so I'm using open mesa drivers. After reboot my maximum display resolution was 1280x1024, but my real maximum (that I correctly had with fglrx drivers) is 1920x1080.
I tried to do something from this wiki: https://wiki.ubuntu.com/X/Config/Resolution to section "Setting resolution changes in xorg.conf -- resolution lower than expected" but it didn't solve my problem, infact I tried to edit xorg.conf with the lines in the attached file but after reboot it says that my xorg.conf is not correctly configured and I had to remove xorg.conf and use the old one I had backed up before. Besides I have "plasma-desktop" crash at startup (only without fglrx drivers, that is with open drivers).
