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). I'll give you some information: Crash log in "Developer Information" section of KDE Crash Assistant: http://pastebin.com/raw.php?i=8stmVCky xorg.conf: http://pastebin.com/raw.php?i=D6MPUEZv Xorg.0.log: http://pastebin.com/raw.php?i=dWDVe03t ** Attachment added: "xorg.conf" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1174042/+attachment/3773428/+files/xorg.conf -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1174042 Title: System crashes with open-source radeon driver Status in “xserver-xorg-video-ati” package in Ubuntu: Confirmed Bug description: I have a Dell StudioXPS 1640 with an ATI Radeon HD 3670. Unter Ubuntu 12.04, I was able to use the proprietary fglrx driver. However, since the new xserver-xorg introduced in Ubuntu 12.10, I am unable to use the proprietary driver anymore, because ATI stopped support for the graphics card in the newer fglrx-versions compatible with the new xserver. I now upgraded to Ubuntu 13.04 and tried to get the radeon open-source driver to work. When I activate the driver by installing the xserver- xorg-video-radeon package, the monitor goes dark, flickers once a few seconds later and the system does not react anymore - the only thing still working is the poweroff button. I did try several custom xorg.conf files (minimalistic copy of the fallback with the radeon driver specified, the same with deactivated acceleration and a bigger one with specific screen modes, etc) and the dbus version without any xorg.conf file - all with the same result. The vesa-driver is unable to detect my monitor correctly and leaves me with 1440x960, which is bad for my monitor, because it is not my native resolution and fuzzy. I'm now stuck with a generic kernel-mode setting, which has my native resolution, but is sluggish and unusable. I do not want to be stuck with Ubuntu 12.04 and an unsupported fglrx driver for the next year or so (until I get a new laptop). Any hints and help greatly appreciated.
