Login screen loop after update - RPI5, KDE

ARM Plasma
1

I have been running EndeavourOS KDE on an RPI5, 8GB as my daily driver for several months. I am very pleased with the performance.

However, after the latest update, I found that I could not get beyond the login screen. That is, it accepted the password, but returned to the login screen.

I tried X11 instead of Wayland with the same result. I went to the command line and tried configuring autologin, with the same result. Also I installed and enabled lightdm, also with the same result and a lot less pretty login screen. So it appears the the problem is not with sddm.

I entered

dbus-run-session startplasma-wayland

and got an “error while loading libPlasma.so.6…..No such file or directory”.

Also the same error when trying to start x11.

Where is libPlasma.so.6? What else can I try?

Welcome to the EndeavourOS forum. :handshake: I hope you enjoy your time here.
Thank you for your interest in Raspberry Pi 5.

I just updated my Raspberry Pi 5 and the main thing was it updated KDE Plasma from 6.6.0 to 6.6.1

This update went OK with no problems.

As per the Archlinux WiKi, libplasma should be libplasma- 6.6.1-1

When you boot up to the sddm window, press Ctrl-Alt-F3 and bring up a Console window.

pacman -Q | grep libplasma
libplasma 6.6.1-1

If libplasma is not 6.6.1-1 update it
sudo pacman -Syu libplasma

If libplasma is 6.6.1-1 then do a

sudo pacman -Syu

just to insure your last update went well.

I had the exact same problem today, after the updates. I actually had that new libPlasma.so.6.6.1 file in my /usr/lib so the update was probably OK however, just like the original poster mentioned, the system was looking for libPlasma.so.6 (which wasn’t there). I tried to symlink it to the 6.6.1 file and i got past the login screen but the desktop still did not come up. I only saw my mouse cursor. So i just reverted the updates.

EDIT: Resolved. You can update.

Thank you Pudge. Doing another update brought in some more changes, and after that the login worked. Maybe the updates were uploaded over a period of several hours and the first update I did left my system in an inconsistent state. It looks like the same thing happened to RPI5-User.

To be sure, I redid the update on a cloned backup from a few days ago, and this time it worked as expected. So I can confirm that the issue seems to have been resolved.

why ? worst case just go diff tty login then type startplasma-wayland .. that get you in GUI (in this case) go from there ..

or use that . no need for sddm or any login manager .. sadly i have KDE still on Usd for test with no pointless login manager

Exactly.

TIP for KDE:
To get your installation even a bit faster, try this.
If you haven’t already, launch “System Settings” and on the “Quick Settings” window, change “Animation Speed” to “Instant”.
If you don’t need file indexing (most users don’t) In a terminal window disable Baloo

balooctl6 suspend
balooctl6 disable
balooctl6 purge
balooctl6 status

Out of curiosity, what are you using for a MSD (Mass Storage Device) such as micro SD, or USB 3 SSD enclosure, etc?
should show baloo is disabled.

Thanks for the tip. It definitely makes a difference.

I’m using a 500GB NVMe SSD, in a Raspberry Pi M.2 HAT.
