I had to manually mkdir -m 1777 /tmp/.X11-unix on a headless machine. (no X11 has ever been run there after installation) On a normal desktop machine this directory will already exist. The symptoms are just a black window after authentication, then a few seconds 'M' logo and then the windows disappears. Greetings, Konrad
