Lightdm fails to start xsession

I switched from xfce4 to i3 a while ago. The first go through, everything worked fine. I then had to reinstall i3 for some reason, and I can no longer enter i3 through lightdm-gtk-greeter. I have to drop into tty2 and manually startx. The greeter launches fine, but then I have a black screen with just a mouse and none of the i3 commands work. Notably, if I uncomment the autologin lines in lightdm.conf, I can boot straight to i3. I do want to have my computer password protected, though. ###.bash_profile # # ~/.bash_profile # [[ -f ~/.bashrc ]] && . ~/.bashrc if [[ ! $DISPLAY && $XDG_VTNR -eq 1 ]]; then exec startx fi ###/etc/lightdm/lightdm.conf # # General configuration # [LightDM] run-directory=/run/lightdm [Seat:*] greeter-session=lightdm-gtk-greeter user-session=i3 session-wrapper=/etc/lightdm/Xsession [XDMCPServer] [VNCServer]
