Bug#1110357: Additional info for bug #1110357 — KDE Plasma 6 Wayland fails without $WAYLAND_DISPLAY



Hi,
This is a follow-up to my submitted bug report (#1110357).

Here is more context:

I am using Debian 13 RC2, fresh install with KDE.

Logging into the Plasma Wayland session fails to initialize $WAYLAND_DISPLAY. That variable is completely missing (echo $WAYLAND_DISPLAY outputs nothing), while XDG_SESSION_TYPE=wayland is set.

As a result, critical KDE daemon services like kded6 crash in a loop. Qt-based applications and KDE components log the error:

Failed to create wl_display (No such file or directory)
qt.qpa.plugin: Could not load the Qt platform plugin "wayland"

kglobalaccel never starts → global keyboard shortcuts (e.g. Fn key) are broken.

The KDE session appears half-loaded, with icons and panel, but no core functionality.

Workaround:

Logging in via Plasma X11 works properly — all daemons and shortcuts OK.

Attached log is from:

journalctl -b | grep -Ei '(wl_display)'

Let me know if you'd like me to attach that file or preview its contents.

Arthur
