Hi,

to see whether KDE Wayland works better when started via gdm3 instead of
sddm (spoiler: No, same way of broken as with sddm), I exchanged sddm
with gdm3. After going back to KDE X11 Session, I found my log being
spammed with the following pattern, repeated endlessly:

Going back to sddm as display manager moves the spam to ~/.xsession-errors (50 GByte at the moment):

How do I get rid of that loop?

Most annoying is that I am not using any of the akonadi stuff and just don't get rid of it.

Greetings
Marc

About the loop: I never seen that before - It normally just fails and than not
try again to start up again. It maybe related with systemd integration of
Plasma. Or do you have any special autostart scripts? And with the newer
versions the wayland support got better, so maybe the issue is solved in
meanwhile?

if you don't use any Akonadi feature and don't want to remove meta-packages. I
would suggest to use akonadi-backend-sqlite and remove the mysql one.
Unfortunatelly you really need to modify your akonadiserverrc config. That at
least should make it start more easily. See the blog entry:
