KDE Plasma Black Screen after Login

Hi @sv_stark,

Have you tried clearing the cache?

This sounds similar, but not the same, as an experience I recently had with a script I created in ~/.config/plasma-workspace/env/ causing my login to hang for an infinite time. So check that as well.

You could try creating a new user profile, and see whether the same happens in that. It’s a quick way to know if it’s profile-related, or not. Cheers.

i did that but same black screen with addition to manjaro hello appearing.

yup did rm -rf ~/.cache/* and rm ~/.config/plasma-org.kde.plasma.desktop-appletsrc rebooted but no change.

Well, here’s where you leave some information about your system and recent logs. This will likely help someone identify the problem. Please provide the output of:

inxi --admin --verbosity=7 --filter --no-host --width
journalctl --boot=-1 --priority=3 --catalog --no-pager

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!

I have already tried chroot before posting and upgraded all packages again. But problems persist.

In that case your and our best bet would be:

I notice you have/had both LightDM and SDDM installed. KDE usually requires SDDM. I imagine you opted for LightDm because it feels a bit lighter. This may be contributing.

output is too long to be pasted here as limit is exceeding.

You could instead use one of the Pastebin type websites, and post the relevant link when done. I don’t use them, myself, so I have none to specifically recommend.

This ought to help:

And probably this:

Here You Go.

lightDM was installed assuming sddm was causing the problem. but as we can see that didn’t work out.

OK. Can you provide the output of:

journalctl --unit=udisks2.service --no-pager

This will be comparatively smaller in length; you should be able to paste it here.

Limit exceeding again so here is the link.

What seems to have happened is that udisks crashed either during or after the update. The last time I saw this (or, a similar) issue, there was nothing conclusive. This is the thread if interested in comparison.

The fastest resolution might be to to start afresh. Before you do that, however, please wait for others to look at those logs in case someone knows of another solution.

Link to udisks2 project, if anyone needs it. These are likely related upstream issues #1198, #727, #969; possibly more.
