Lightdm does denied access for all users

Hi,

I used lightdm and lxdm together and catch a lot of errors, one of that not often issue 'cannt make auth'
I remove and reinstall with drop cache and left just only Lightdm

yay -S lightdm lightdm-guest shikai-theme lightdm-settings lightdm-gtk-greeter light-locker

I try use reinstalled lightdm application on test mode

lightdm --test-mode -d

And i can't doing access 'password is incorrect' - FOR ALL USERS
Before that i has 2-3 success access login btw 1 failure access but now nothing

 
$ lightdm --test-mode -d

Re: Lightdm does denied access for all users

catch a lot of errors, one of that not often issue 'cannt make auth' … doing access 'password is incorrect' - FOR ALL USERS

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855 - post the actual lightdm log from /var/log

You might also benefit from https://deepl.com/

Wild guess: is your password qwerty-safe? (You're probably not using a US-QWERTY keyboard?)
Please also post your Xorg log, https://wiki.archlinux.org/title/Xorg#General

Re: Lightdm does denied access for all users

I didnt find problem but installed dm on the GTK3 and hasnt problem.
I suspect my keyboard and pam.d/ or environment variables.

On the internet a lot of people with same problem as in my errors log.

https://deepl.com/ - I assume you're talking about the lightdm greeter? And you changed from something (webkit?) to thr gtk greeter?

Sorry,

I would like say that what LightDM and lxde-gtk2 has authentication problems. And solved this issue, used packages with -gtk3

extra/lxdm-gtk3 0.5.3-8 (100.2 KiB 337.6 KiB) [lxde-gtk3] (installed)
Lightweight X11 Display Manager (GTK+ 3 version)

Re: Lightdm does denied access for all users

Oh, you really meant lxdm, not lxde
You cannot use lightdm and lxdm at the same time. They're different tools that do the same thing.
And apparently you're using LXDM.

Re: Lightdm does denied access for all users

Nah, gtk3 wird jetzt stabil und deswegen nutzt gimp das jetzt auch

If you're using lxdm, lightdm is kinda irrelevant here and you might remove it from the system.

Also, ahem…
