SESSION_DIRS does not work
First of all thank you for this nice greeter, I have ported it to PCLinuxOS to have properly functioning Wayland sessions and it works very nicely.
However, I have an issue where SESSION_DIRS seems to not work. On PCLinuxOS, X11 sessions are stored in /etc/X11/dm/Sessions and there is no /usr/share/xsessions. I figured out that its still pointing towards /usr/share/xsessions by symlinking /etc/11/dm/Sessions to /usr/share/xsessions and now you can see X11 sessions in ReGreet. But by default, even with SESSION_DIRS set to SESSION_DIRS=/etc/X11/dm/Sessions:/usr/share/wayland-sessions when building, it only sees Wayland sessions.
Does the greeter have permissions to read /etc/X11/dm/Session? Also, could you include the logs?

It should. /etc/X11/dm/Sessions is drwxr-xr-x

hmm seems like u also have to unset XDG_DATA_DIRS to override where it looks for session files a bit weird ngl - id rather just set SESSION_DIRS or a cmdline flag to override it
