This appears to be a follow-up to Ran test for ligthdm bug Says Xserver no path found - if you have a working internet connection you can try re-installing the X server core package (sudo apt install --reinstall xserver-xorg-core). The non-existance of the .Xauthority file is normal if temporaryuser has not previously started an X session.
