KDE Plasma Black Screen after Login

This all makes it sound like…well, like something. Stating the obvious I know, right?!

Anyway, I’d recommend starting a Live environment, entering a chroot environment, doing a complete re-sync and handling any and all .pacnew files before rebooting.

How to chroot

  1. Ensure you’ve got a relatively new ISO or at least one with a still supported LTS kernel.

  2. Write/copy/dd the ISO to a USB thumb drive.

  3. When done, boot with the above mentioned USB thumb drive into the live environment.

  4. Once booted, open a terminal and enter the following command to enter the chroot encironment:

manjaro-chroot -a
  1. If you have more than one Linux installation, select the correct one to use from the list provided.

When done, you should now be in the chroot environment.

But, be careful, as you’re now in an actual root environment on your computer, so any changes you make will persist after a restart.

From within the boot environment, tun the following the completely resync the system:

pamac upgrade && pamac upgrade --aur --devel || echo -e '\033[0;91mThere was an error upgrading the system. AUR packages not upgraded.\e[0m'

This will update your system and ONLY if that was successful update any AUR packages.

a Reminder: While use of the AUR is possible, it’s neither recommended nor supported.

I recommend pamac instead of pacman, especially for newcomers as pamac was developed by Manajaro (developers) for Manjaro and just takes care of more thing than pacman. For example:

When done, exit the chroot enviro9nment:

exit

Now, hold your thumbs, cross your heart, do a little dance and, finally, reboot.

I don’t know if it will, but I hope it helps!
