lightdm doesn't start

I ran the following to debug:

lightdm --test-mode --debug

the output:

I have edited the /etc/lightdm/lightdm.conf file and put the pantheon specification for the seat:* section as per the wiki. Not sure what's causing this error on boot.

Re: lightdm doesn't start

I haven't made the ~/.xinitrc file because I thought you didn't need to when using a display manager. The wiki says the following in the Xorg page: The Xorg(1) command is usually not run directly, instead the X server is started with either a display manager or xinit. Sorry if this is trivial but this is my first linux install.

lmao I didn't realise that was the signature, I thought it was part of the response, sorry.

Re: lightdm doesn't start

what do I do with that command? It doesn't seem like it gives me any useful information, just basic info about the package

Re: lightdm doesn't start

Post the output.
The principal question is whether it's installed and intact (or some files deviate in existance or premisions etc.)

The signature answers to typical issues ;-)
