Comment 2 Eric Armbruster 2023-05-09 09:35:08 UTC

Correction: its enough to simply turn on/off the TV screen. After that my screen order is scrambled.

Comment 3 Nate Graham 2023-05-15 23:14:11 UTC

When you ran `kscreen-doctor -o` up there, was that before or after the problem happened?

What's helpful is to get the output of that command both before and after the issue happens, so we can see what specifically has changed.

Comment 4 Eric Armbruster 2023-05-16 06:36:54 UTC

Ok, got the following results after performing these steps:
1. Boot-up, turn TV screen on, change screen order with Meta+P to be correct.
2. kscreen-doctor -o
3. Turn tv on/off
4. kscreen-doctor -o

Comment 5 Eric Armbruster 2023-05-16 06:37:57 UTC

After 3 the screen order was scrambled again.

Comment 6 Nate Graham 2023-05-16 15:52:38 UTC

Looks like the screens' geometry values are reversing. Before, eDP-1 had a geometry value of 0,0 and for HDMI-A-1, it was 1920,0. After, they're reversed.

Is the "KScreen 2" service listed as running in System Settings > Startup and Shutdown > Background Services?

Comment 7 Eric Armbruster 2023-05-16 17:30:04 UTC

Yes

Comment 8 Nate Graham 2023-05-17 14:52:55 UTC

Thanks.

Comment 9 Eric Armbruster 2023-05-19 07:28:18 UTC

Hmm, cant reproduce anymore. Closing for now.
