Pi4 black screen after logon

I just installed a bunch of updates on a Pi4 8GB with Manjaro 64bit with KDE Plasma and now after I log in the display output completely turns off, how do I fix this?

I have shell access is there anything I can type in to troubleshoot?

I’m about to throw this useless thing at a wall nothing ever works on linux!

Does this help:

Hello and welcome to the forum.

I hope you remember the day you posted was a weekend and not many community members are online in that day.

It is your choice. If you want to rant then its ok but operating systems on arm hardware is always under heavy developement so if things go south then you need to learn to debug it and share the logs for community members to understand so they can help you fix it.

Can to share the output of following commands

uname -a

inxi -Fzxi

sudo systemctl status sddm

Good luck.

Eventually the mouse and keyboard completely stopped working at the login screen so I gave up and restored a backup of the SD card, thanks for understanding and sorry to completely change the issue but now after restoring the backup and installing all updates I restarted the Pi and the UI is extremely slow to update and the mouse movement is laggy like there’s no graphics driver installed.
Can we continue this here or shall I create another thread?

Take a look at Mouse issue on xfce

All issues right now are related to fkms which becomes deprecated from RPI Team on new kernels.
