I originally had I3 only installed and it shows up in lightDM (along with I3 debug).
I've added dwm and it works just fine if I disable lightDM and just long into the terminal and run startx (I added dwm to the .xinitrc file).
The problem is that dwm doesn't show up as a choice in lightDM if I use the lightDM service, I3 and I3 debug are the only two options.
Any suggestions ?
