I'm just installing arch on my new laptop and I'm having some issues setting up my desktop environment. When I enable the lightdm service, it just boots to a blank screen.
Things That Work
- "startx" - starts Xorg and I can type into the terminals and move the mouse cursor
- "startxfce4" - if I create an .xinitrc (for root or non-root) and put in "exec startxfce4", xfce4 succesfully boots
- "lightdm --test-mode --debug" - interestingly this works. Starts lightdm and lets me log in
Things That Don't Work
- booting into lightdm (blank screen)
- "gnome-session" shows a blank screen and then "oh no! something went wrong" message with logout button (via terminal, test mode lightdm, or .xinitrc)
- same problem with other DMs - GDM and SLIM both boot to blank screen
