SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Start computer
2. Log into Plasma
3. 

OBSERVED RESULT
Running on Debian Bookworm.
I have three screens. The left and the right are portrait oriented and the
middle one is landscape oriented and the default screen. After an apt upgrade the system
forgets that the middle screen is the default one. The list of screen priorities
is correct, but the system still decides to make my very left screen default (the one with
panels on). This happens every time I log in. Note that the positions are fine. It is just the issue that it forgets which one is the main screen.

To fix it I have to change the screen priorities list, save, change back, save.

EXPECTED RESULT
I expect that the system will look at the screen priorities and make the
screen with the highest priority the default screen.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.26.90

ADDITIONAL INFORMATION
I have also logged a bug with Debian's maintainer on https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1030552
Comment 1 David Edmundson 2023-02-07 23:33:53 UTC 
Can you include output of kscreen-doctor -o

and say if the priority looks right there or not
Comment 2 Marco Martin 2023-02-08 09:15:26 UTC 
X11 or wayland?
Comment 3 Marco Martin 2023-02-08 11:47:27 UTC 
can you also paste the output of the command kscreen-console ?

I'm curious if all the edids are found correctly, as is a known problem of erratic behavior when there are screens with invalid or duplicated edid (especially on displayport)
Comment 4 Jonas Arndt 2023-02-08 13:22:36 UTC 
Here is the output of kscreen-doctor -o

Comment 7 Jonas Arndt 2023-02-08 13:26:10 UTC 
All the commands were run when the wrong screen (the left one) was primary.  Currently I have an xrandr script I use to set them right:

xrandr --output eDP-1 --off --output DP-1 --mode 1920x1080 --pos 0x0 --rotate right --output DP-2 --off --output DP-3 --off --output DP-3-1 --off --output DP-3-2 --primary --mode 1920x1080 --pos 1080x420 --rotate normal --output DP-3-3 --mode 1920x1080 --pos 3000x0 --rotate left

Currently as in, you're using this as a workaround for the Kscreen bug, or you always used to have an xrandr on startup?

No I just use xrandr as a work-around for this problem. I suspect my upgrade systemsettings:amd64 (4:5.26.5-1, 4:5.26.90-1) on February 2nd caused this issue
Comment 10 Tomas 2023-02-11 08:51:56 UTC 
The same bug affects me. X11. I have 3 monitors and one of them is portrait monitor.

Comment 11 Matt Jolly 2023-02-15 04:05:59 UTC 
I am seeing a similar (or the same) issue on Plasma 5.27 (Wayland).

When I switch back across to this workstation with my KVM the screen priorities are disregarded and my leftmost screen is always selected as the highest priority.
Comment 12 Matt Jolly 2023-02-15 05:30:24 UTC 
Notes: No EDID emulation on the KVM

Configuration as manually corrected below, when I switch the KVM back to KDE *most* of the time (but not always) DP-1 and DP-2 switch priorities.

I did not notice this with earlier Plasma versions; however without EDID emulation rotation settings and orientation were a bit flaky. That seems to have been resolved by the latest update - orientation and layout has remained consistent.

Created attachment 156420 [details]
Screen layout in settings
Comment 14 Félim Whiteley 2023-02-18 10:28:37 UTC 
Ah damn adding attachment wiped my message... ok so same for me, Steam is the major issue. All games load on the leftmost screen in portrait, mangles the resolution, moving the game with shift+win+right_arrow moves it over but the game usually goes garbled or uses half one screen with the pointer out of sync with where it is in the picture.

It certainly is for me on a fully updated Neon. As an example my layout is left screen portrait centre and right landscape, playing in a steam game it will often start on far left, on the games that allow you to set the screen, say "Isonzo", it starts on the right screen but only half of the screen is clickable. Like the mouse pointer clicks the top half of the portrait screen and the left half of the centre screen. Very odd. So it will display right but I can only get to half the stuff. Ironically it's totally playable as most settings are thankfully to the left. But clearly not ideal! :-)

Happy to demo for you if that helps, Rust Desk or the like...
Comment 17 Harald Sitter 2023-04-18 17:37:33 UTC 
Can you grab debug output while a game is running incorrectly? And maybe also add the output of xrandr. If I'm reading your earlier output correctly then the center screen is correctly marked primary there.

xrandr: always try to update primary

When screen0 gets disconnected the atom essentially says it is priority
1 but we ignore it on account of being disconnected/disabled (this
happens inside priority()). This caused setPriority to exit early and
not do anything. Upon plugging screen0 back in the atom comes into play
again and it is still saying the screen is priority 1, but really
another screen was/is priority 1. What happens then is that since the
atom says the screen is priority1 == newpriority == noop.

tldr:

- screen0 disconnect: priority=0 == newPrirority=0 -> noop
- screen1: priority=2 != newPriority=1 -> set_primary
- screen0 reconnect: priority=1 == newPriority=1 -> noop
- screen1 is now primary but the entire kscreen system thinks it should
be screen0

to solve this problem simply update the primary regardless of the
property change, at worst this is noop on the xcb side of things, at
best we ensure the primary is in sync

Comment 21 Félim Whiteley 2023-04-21 16:41:22 UTC 
Not sure why but Steam just won't generate a debug log for the game, I've tried the

PROTON_LOG=1 %command%

In the Isonzo options but it's of no use... I have made this poorly handheld and shoddy handheld recording of the inability to click past a certain point, like the clicks include the first 1080 pixels of the vertical leftmost monitor and the remain left 840pixels of the centre. I'll include xrandr at the end and will try get a debug log from Steam. Sorry for the delay, one of those weeks.

No worries I will test as soon as Neon updates. An interesting thing I discovered not quite understanding Steams options. So it turns out Isonzo is Native and in Native mode the weird pointer issue occurs. I was able to run it in Proton 8 forced mode and the GFX are fractionally less performant but the whole screen is clickable and runs as expected! Strange one, what I will do is test in both modes as soon as the update is out. Thanks for all of your work!

I haven't tested much anything since back when I reported the bug. I am on Debian Bookworm and plasma 5.27.2-1 now. For some reason it all works now. I don't anymore need to have a login script with xrandr. It works on Xorg and Wayland. The middle landscape oriented screen is the default screen now.

Yeah, because we fixed it! :D In all seriousness, thanks for testing! I'm happy to hear that things are working properly without the need for manual workaround scripts.
