[RESOLVED] Wayland session with 2.5 screens? Semifunctional screen via TB4 dock.

[yaccuber]

My laptop seems to try to be that statistical animal, with exactly 2.5 screens, sorry, for the joke.

Odd thing on my Kubuntu 24.04 system:

hardware:
Lenovo T16 G3 U7 155U + Thinkpad Thunderbolt 4 Dock
Plasma wayland session

andreas@dogmatix:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 24.04.2 LTS
Release: 24.04
Codename: noble
andreas@dogmatix:~$ uname -a
Linux dogmatix 6.11.0-17-generic #17~24.04.2-Ubuntu SMP PREEMPT_DYNAMIC Mon Jan 20 22:48:29 UTC 2 x86_64
x86_64 x86_64 GNU/Linux

One external screen attached directly to the HDMI port on the laptop, one attached to the HDMI port of the dock, one attached to the DP of the dock. Laptop lid is closed.

Now in the Settings app, 3 screens show up. See

Now in the Edit Panel/Panels & Desktop view, only TWO screens show up:



The irritating thing is, the middle screen has no right click menu, no background, I cannot create widgets on it. The only thing I can do is drag windows to it.

Funny thing.

Any ideas?

Sigh, guess posting about helps, one reboot, and the persistent problem that bothered me for months is gone,

A kernel upgrade happened this past week, which gains Noble users Oracular's 6.11

aka better Thunderbolt support maybe, but then again, you seem to already have rebooted since you got that.

But glad it works now.
