lemurs: Starting post-login environment failed (spectrwm)

Hi,

Feel like I’m missing something obvious, but after a trying few different combinations I currently have:

/etc/lemurs/wms/spectrwm

#!/bin/sh

exec spectrwm

Nothing at all in ~/.xinitrc if that makes any difference

When I boot I get the lemurs login prompt with ‘spectrwm’ at the top, fill in my username and password and it goes to a blank screen. Log appears to show everything running fine up to Run X server, then just says:

[lemurs::ui][ERROR] Starting post-login environment failed

If I disable the service, reboot, login on tty, put exec spectrwm into my ~/.xinitrc and run startx, spectrwm loads as expected.

Any ideas please?
