Comment 2 for bug 989577

I am having exactly the same problem. I set up a Kubuntu /Win8 dual boot on an Asus zenbook. ubuntu boots, and then brings up the nice dual boot screen, but when I pick ubuntu, I just get the wallpaper but no kde gui. When I alt-ctl-F1 into terminal, and try something like kdesudo kate, I get kdesudo: cannot connect to X server.

I don't have any of the entries that themroc has in /etc/sudoers. This is a totally fresh install.
