Description Arcadiy Ivanov 2023-06-29 19:23:15 UTC 
This just happened recently. When selecting "Save displays' properties: for only this specific display arrangement" during applying display configuration the display configuration fails while screens reset and initialize. Moving to "for any display arrangement" is a workaround to make things work.

This involves 2 x 4k displays via USB-C dock  plus primary laptop screen.

STEPS TO REPRODUCE
1.  Start with "built-in screen". Select "for only this specific display arrangement" option in screen configuration.
2.  Tile the dock's displays around your built-in screen. Click Apply.
3.  Observe the flickers of initialization and "New output detected" appearing several times. Observe that flickers stop and only built-in screen is configured with dock's displays gone.
4. Repeated the same procedure (1 - 3) with "for any display arrangement". Observe same flickering etc but all screens configuring normally with all specified displays.

OBSERVED RESULT
Only built-in screen configured

EXPECTED RESULT
All 3 screens are configured

ADDITIONAL INFORMATION

I'm going to correct myself. This happens in either mode now, but in "for any display arrangement" it's more likely to succeed.

Comment 4 Nate Graham 2023-09-14 19:13:56 UTC 
I'm afraid "for only this specific display arrangement" has already been removed in Plasma 6 as it caused an endless stream of bugs, so probably you should stick with your workaround. We won't be able to fix the problem with the now-removed setting, sorry.
