From time to time I'm getting 'Failed to start Light Display Manager' - black screen

Hello!
I’m using Manjaro quite long and so far didn’t have any problems with it BUT… since couple of weeks I have problems with booting up my machine - it’s showing black screen and login window doesn’t appear and I have to do hard reset. It doesn’t happen every boot - it happens randomly. Same happens with 5.15 and 5.16 kernel.

Here’s a scrap of my journalctl with amdgpu errors:

Any ideas? Let me know if any more logs are needed

For the above method to work you need to install the lightdm-slick-greeter package.

Thanks for quick response!

Actually I’m using lightdm-webkit2-greeter and it’s specified in /etc/lightdm/lightdm.conf under Seat* configuration

I’ve also found few errors at Xorg.log
