I've the same problem and I hope a solution in these days. It's probably a problem of name because when i try to install software like wine, teamviewer & co. "apt" asks me to remove these packages:
libgl1-mesa-dri-lts-quantal libgl1-mesa-glx-lts-quantal libglapi-mesa-lts-quantal libxatracker1-lts-quantal x11-xserver-utils-lts-quantal xserver-common-lts-quantal xserver-xorg-core-lts-quantal xserver-xorg-input-all-lts-quantal xserver-xorg-input-evdev-lts-quantal xserver-xorg-input-mouse-lts-quantal xserver-xorg-input-synaptics-lts-quantal xserver-xorg-input-vmmouse-lts-quantal xserver-xorg-input-wacom-lts-quantal xserver-xorg-lts-quantal xserver-xorg-video-all-lts-quantal xserver-xorg-video-ati-lts-quantal xserver-xorg-video-cirrus-lts-quantal xserver-xorg-video-fbdev-lts-quantal xserver-xorg-video-intel-lts-quantal xserver-xorg-video-mach64-lts-quantal xserver-xorg-video-mga-lts-quantal xserver-xorg-video-modesetting-lts-quantal xserver-xorg-video-neomagic-lts-quantal xserver-xorg-video-nouveau-lts-quantal xserver-xorg-video-openchrome-lts-quantal xserver-xorg-video-r128-lts-quantal xserver-xorg-video-radeon-lts-quantal xserver-xorg-video-s3-lts-quantal xserver-xorg-video-savage-lts-quantal xserver-xorg-video-siliconmotion-lts-quantal xserver-xorg-video-sis-lts-quantal xserver-xorg-video-sisusb-lts-quantal xserver-xorg-video-tdfx-lts-quantal xserver-xorg-video-trident-lts-quantal xserver-xorg-video-vesa-lts-quantal xserver-xorg-video-vmware-lts-quantal I said "it's a problem of name" for these packages because wine and other software don't support the new names of xorg. Please solve these problem before Ubuntu 13.04-day.
