Ubuntu – X fails to load

xorg

Today I tried to boot Ubuntu with 9wm (which I had installed before), first by modifying the GRUB boot from 'quiet splash' to 'text', later adding it to LightDM. As it didn't work, I removed the LightDM entry and restored GRUB. But when I try to login with any window manager in LightDM, it just stops and opens LightDM again. If I try to run startx from a TTY, it shows errors, saying all time that No protocol specified. What can I do?

UPDATE: It just happens with my user, logging in with another one works.

Surprisingly, the workaround for this problem is very simple. Just remove all .Xauthority files in your home folder with this command:

rm ~/.Xauthority*
