Description Tony 2016-08-13 22:34:46 UTC
My setup:
I have it setup as fallows, my "primary display" is connected to the 2nd dvi port (DVI-I-2) of my video card. The one that's off is connected to DVI-I-1, i never have set this one as my "primary display".

The issue:
I shutdown my pc, turn off the 2nd monitor (DVI-I-1) but left it plugged into the video card. When i boot again and log in i get the desktop that belongs to my 2nd screen, the one that is off  as my "primary display".
On System Settings > Display and monitor i see that both monitors are detected, even though one of them is off and that my "primary display" (DVI-I-2)  haven't changed.

I have to restart plasma (kstart plasma-desktop) in order to get thinks right.

Reproducible: Didn't try

Steps to Reproduce:
1.Set (DVI-I-2) as primary display.
2.Turn off your PC, turn off the monitor on (DVI-I-1) and leave it plugged.
3.Reboot and log in.

Still a problem on 5.15.4. Related to display settings not saving.

Same issue here.

SUMMARY
I have two monitors. My graphic card is Nvidia. My main (default, HDMI) monitor is at right side, the secondary (DVI) one is at left and rotated 90 degrees clockwise. The same config is shared thru "Screen" Plasma dialog and in Nvidia configuration (as it should be).
Each time I reboot and Plasma begin to load, all widgets and panels of second monitor appears in the first one and viceversa. After some seconds (finishing loading desktop), all widget and panels are showed correctly in first monitor, but second is black. I can move mouse over it, but no click reaction or dialogs (for example, clicking on it and press <Alt><F2>). I need go to "Screen" Plasma dialog, make any change (for example, rotate 90 anticlockwise), apply changes (then second monitor shows content) and then again configure to 90 clockwise and accept (to let it as it should be).

STEPS TO REPRODUCE
1. Configure second monitor rotated 90ΒΊ and apply
2. Reboot system

OBSERVED RESULT
Second monitor doesn't show nothing, but mouse pointer.

EXPECTED RESULT
To recover last configuration on each reboot.

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Plasma 5.25 or 5.26?

If it is, please change the status to CONFIRMED when replying. If not, or if you can't because you no longer use this setup, you can change the status to RESOLVED WORKSFORME. Thanks a lot!
