After choosing the proper monitor configuration (DVI-0 as primary, HDMI-0 as secondary on the left of the DVI-0 monitor) and the proper resolutions, DVI-0 as 1920x1200 and HDMI-0 as 1920x1080 and saving everything the system sometimes "forgets" every setting. Reproducible: Sometimes Steps to Reproduce: 1. Go to system Settings and Display configuration 2. Drag the HDMI-0 display to the right side of the DVI-0 display 3. Click on DVI-0 and set its native resolution (instead of the 720xSomething that is selected), confirm 4. Click on HDMI-0 and set its native resolution (instead of the 720xSomething that is selected, confirm 5. Set the DVI-0 monitor as the primary 6. Click apply, exit system configuration and perform a clean shutdown of the system using the graphical menu Actual Results: You can see that in the transition from SDDM to Plasma Desktop that the resolution changes. Inside plasma you will notice that the monitor is stretching a very poor resolution to fill all available pixels. Inside System Settings -> Display configuration you'll see that both monitors are piled one on top of the other, the resolutions have fallen back to 720xSomething and the primary monitor reverted to HDMI-0. Expected Results: Whenever the system boots again or a new user session is created plasma desktop will keep all the settings that were specified. I have a two monitor setup. My primary monitor is a 1920x1200 flat screen. My second monitor is a regular FullHD TV that sits to the right side of the primary. I use the HDMI screen once in a while. Most of the time it's either turned off or displaying regular TV. It is very difficult for me to plug and unplug the HDMI cable, because it is hidden behind the fixed desk. Starting another user session is almost a sure way to mess up the Display configuration afterwards (after a reboot).
Additional information. I've used the second monitor. This time, the DVI-0 one was correctly configured, but the other was not active. I've configured both. Later on, when I've booted again the system (with the TV turned OFF), the configuration was again missing. The resolution that it is selecting by default is 1280x1024. But only *after* the plasma-desktop shows up. SDDM is correctly using the native resolution.
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, and paste the output of `kscreen-doctor -o` when it's working properly, and then right after you make the bug happen. 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!
