I am using manjaro (mate) on both a lenovo T14 and a x13 laptop. (both AMD gen1) (5.10.23-1)
After applying recent upgrades, lightdm fails to start at boot. The Error occurs on both laptops. Leaving me with a blank screen at startup.
One way to recover is to log on a console (ctrl + alt + f2) and restart light dm
systemctl restart lightdm
It seems lightdm is trying to start before the video driver is completely loaded (xorg complains about /dev/dri/card0 in the log file, and the dri initialization timestamp (dmesg) is posterior to the error) .
I fixed it is temporatily by adding
ExecStartPre=/bin/sleep 5
into
/etc/systemd/system/display-manager.service
in the [Service] section.
Is there any official fix for this ? Did anyone else experience this ?

Apparently a (better?) option is to use KMS https://wiki.archlinux.org/index.php/Ke … _KMS_start
Edit
/etc/mkinitcpio.conf
Add amdgpu to the modules array
MODULES=(amdgpu)
Rebuild the initramfs
# mkinitcpio -P
Solves the issue right away.

Nice information, but.......
This is not the manjaro forum.

Thanks a lot for the info pal.
Arch Linux really rocks and I appreciate all the hard work put into it, I do use and promote the headless distro *a lot* everywhere I can.
Unfortunately I have a life and cannot use it for desktop use.
Note that I fixed the problem myself, and mainly posted the solution for the (sorry non arch) community, hopefully nobody was hurt.
