I am now experiencing an additional problem. When I start up Plasma, the panel appears on the left monitor. When I check the containments window, it believes that the leftmost monitor is the primary monitor. But the system settings window shows that the rightmost monitor is the primary window. Restarting plasmashell doesn't seem to make a difference. To get the configuration back the way I want it, I change the left monitor to primary, hit apply, and then change it back, and hit apply again.

I don't know if this part is actually #461822, or if it's more related to my initial submission.

Either way, I will have to move back to Kubuntu 22.04 and Plasma 5.25 for now, because my particular multi-monitor situation has regressed pretty badly. I will keep Neon and 5.27 around to get you more info when you need it; please let me know.

The xrandr output shows  DP-1-1 disconnected, the kscreen output shows DP-1-1 connected

Are these different program outputs of the same setup?

That's correct.

I can confirm this issue.
When I power off/on both of my monitors KDE loses track of the primary.
The secondary becomes primary which is confirmed by xrandr while KDE still shows the "correct" setting.

*** Bug 469152 has been marked as a duplicate of this bug. ***

5.27.5 fixed the issue.

Likely related to #465396 and fix https://invent.kde.org/plasma/libkscreen/-/commit/49cc50e629d55d258218bbe5e0abb0c6e93951e3

Nice! Make some logical sense.

Trent M, can you confirm this?

I can confirm this, with some caveats.

So, the xrandr command line client is still showing an incorrect configuration. But while I was using Kubuntu 22.04 w/ Plasma 5.25 waiting for fixes on this, I noticed that its xrandr was doing the same thing. It was exhibiting the correct behavior--games start up on the right monitor, the virtual desktops only on primary script worked--but xrandr showed the completely wrong thing.

So yes, I can confirm that the *behavior* is now correct again. Virtual desktops only on primary works again, and games are starting up on the correct monitor. Is the xrandr CLI's incorrect information just a red herring? One thing I can say is that xrandr no longer believes the disabled laptop screen is the primary monitor; it now believes DP-1-2 is the primary. That much did change, and that connector is consistent with what the primary monitor is supposed to be.

I won't mark it as resolved myself because I'll leave it up to you all to decide whether or not xrandr's CLI saying the wrong thing is actually a problem. The behavior being correct is enough for me to use Neon as my daily driver again. 🙂

Hmm, I'm confused. You said:

> xrandr command line client is still showing an incorrect configuration

And then:

> One thing I can say is that xrandr no longer believes the disabled laptop screen is the primary monitor;
> it now believes DP-1-2 is the primary. That much did change, and that connector is consistent with what

And then:

> xrandr's CLI saying the wrong thing

So is the xrandr command line tool showing the wrong primary monitor or not? :)

Sorry, I guess I didn't explain it clearly. xrandr's CLI says that my active monitors are eDP-1, which is my laptop screen, and DP-1-2, which is my rightmost external monitor. But my actual active monitors are DP-1-1 and DP-1-2. My laptop screen is disabled. The lid's shut because it sits in front of my left monitor. This is reflected in the kscreen-console output.

So xrandr incorrectly thinks I'm using eDP-1 and DP-1-2, whereas I'm actually using DP-1-1 and DP-1-2.

There's one part of the issue that's solved, the one that affects usability the most. My primary monitor is correct, it's the rightmost one. And things that depend on that information are working again. What isn't solved is that xrandr thinks my leftmost monitor is the laptop screen, whereas it's actually an external screen, and kscreen has this correct. I don't know if it actually breaks anything significant, though. The resulting screen geometry is still correct. Both the laptop monitor and my left monitor are 1080p, and both xrandr and kscreen-console show they're side-by-side with the correct monitor indicated as primary.

I was curious what would happen if I made the leftmost monitor primary. So I tried that, and xrandr still thinks the laptop monitor's on. And now it doesn't indicate any primary at all! Here's the xrandr output from that case. Note that my rightmost monitor has now moved to DP-1-3 for no discernible reason. kscreen-console shows this too. One of the very things that motivated the big multi-monitor rewrite!

Sorry to double-post; looks like something in the new xrandr output escaped my notice until I posted it here. It *does* actually indicate a primary: DP-1-1, which it thinks is not connected at all. It also doesn't indicate that any particular mode is selected on eDP-1-1; there should be an asterisk by the one in use. So it's not using any mode, but it's connected and assigned to a screen position. 🤔

Ok, thanks!

I still have this problem on Fedora 38 with 5.27.5 (Zawertun copr).
My main monitor in the kde conf is the right (➡️) one but xrandr thinks it's the left (⬅️) one, so the relevant apps open in the wrong monitor. 
Noted this is from a fresh Fedora install so I only had 5.27.4 and 2.27.5 if that's any relevant.
