Description aeon 2025-02-13 18:40:35 UTC

on archlinux when i try to enable via the toggle it creates 2 systemd user services:
~/.config/systemd/user/plasma-krdp_server.service -> /usr/lib/systemd/user/app-org.kde.krdpserver.service
~/.config/systemd/user/plasma-workspace.target.wants/app-org.kde.krdpserver.service -> /usr/lib/systemd/user/app-org.kde.krdpserver.service

automatic KRDP start fails because of the following error:
plasma-workspace.target: Job app-org.kde.krdpserver.service/start deleted to break ordering cycle starting with plasma-workspace.target/start

looking at the service file, the current one is:
***

[Install]

Alias=plasma-krdp_server.service
***

however, in the beta the autostart worked.  there, the service file was:
***

the workaround i found to get krdpserver to autostart properly was as follows:
disable the autostart that the stable release creates making sure the user systemd does not reference krdpserver
copy the service file that was used in the beta to ~/.config/systemd/user
execute: systemctl enable --user plasma-krdp_server.service

Same issue on Fedora Kinoite 41

The workaround using the beta service file doesn't seem to work for me
Restarting the stable service app-org.kde.krdpserver after startup does work so I just created a timer to start with a delay for now

Comment 2 Bernhard 2025-02-16 15:55:09 UTC

Can confirm, also affects KDE Neon (User) with Plasma 6.3 and the exact same errors.

Git commit ad393302a1e17889067fd139c28962b4b3791fc1 by David Edmundson.
Committed on 17/02/2025 at 12:15.

Fix systemd startup

plasma-workspace.target is explicitly marked as being before
graphical-session.target. If krdpserver is set to come up after
graphical-session.target this creates an issue that plasma-workspace
can't be marked as up until this is up, and we can't start
graphical-session yet.

Anything wanted by plasma-workspaec needs to have dependencies set
explicitly.
