[SOLVED] lightdm crashes when I lock bspwm

Superjolly002 · 2020-12-11 09:20:10

Hi everyone,

I switched to bspwm recently, and I found a little bit problem when I try to lock system using light-locker.
lightdm works when I enter the password, but when I login it shows me a black screen.

$ systemctl status lightdm

If you've recently upgraded light-locker to 1.9.0-3, then it's probably this bug https://bugs.archlinux.org/task/68905?p … ght-locker downgrading to 1.9.0-2 will solve the problem until there's a fix.

Superjolly002 · 2020-12-12 09:11:18

I have downgraded light-locker, and it still doesn't work:

$ light-locker
(light-locker:3866): Gtk-WARNING **: 10:09:26.367: Theme parsing error: gtk.css:3611:22: 'none' is not a valid color name

** (light-locker:3866): ERROR **: 10:09:26.385: session_id is not set, is /proc mounted with hidepid>0?
[1]    3866 trace trap (core dumped)  light-locker

But if I run lxlock works, while with light-locker 1.9.0-3 it doesn't work.

Is this normal?

Okay- you must have a different problem.
