I have an XUbuntu installation that uses LightDM that for some reason unkown to me went gabooey yesterday - black screen with just the mouse pointer on booting. (TTY's still working.)
After much reading I've reinstalled LightDM and now I get to the XUbuntu splash screen but no further.
DEBUG: Seat: Failed to find session configuration xubuntu
DEBUG: Seat: Failed to find session configuration lightdm-gtk-greeter-ubuntu
Can someone tell me exactly what files LightDM is looking for and where it is looking for them?
There are .conf files with those names in /etc/lightdm, I've also tried copying them to other folders I've seen mentioned in posts. I've also tried adding specific xsessions-directory and xgreeters-directory options to lightdm.conf but nothing seems to work.
Any suggestions, much appreciated.
