Does that file exist? If so, ls -ld /var/lib/lightdm/.Xauthority If not, ls -ld /var/lib/lightdm Hell, just do both regardless of whether the file currently exists. It's one command with two lines of output. Should be the first thing you do. See if you can figure out which user lightdm is trying to run as. Try to make it so that user can write that file, either by removing the existing file, or chowning it, or fixing the permissions on the directory. Whatever is indicated by the lightdm changelog. Hopefully there's a note in the lightdm changelog about this. Or in NEWS.
