After recent updates, kscreen no longer sets the correct resolution for a couple of Dell monitors I'm using. It also doesn't show the dropdown box to enable resolution changes. Using arandr, correct resolution choices are available and changing resolution works. Deleting .local/share/kscreen does not resolve the issue. Reproducible: Always Steps to Reproduce: 1. Open system-settings->Display and Monitor->Display configuration 2. Both (identical) Dell monitors are set at 1280x1024, instead of 1600x1200, with no ability to change 3. Starting arandr and selecting 1600x1200 for both monitors works kscreen did allow resolution changes until recent updates, so there has been a regression. System Settings shows version 5.4.1, built against QT 5.4.2 I'm using a Dell laptop with the lid closed. Intel graphics. The config file generated in .local/share/kscreen is dumped below: [ { "enabled": false, "id": "cc43fc659b4d57e88e2b0b678cf58347", "metadata": { "fullname": "xrandr-unknown", "name": "eDP1" }, "pos": { "x": 0, "y": 0 }, "primary": false, "rotation": 1 }, { "enabled": true, "id": "f44a83ae7db4319212ddfb24045199bf", "metadata": { "fullname": "xrandr-DELL 2001FP-C08815BF0P0L", "name": "DP1-1" }, "mode": { "refresh": 75.024673461914062, "size": { "height": 1024, "width": 1280 } }, "pos": { "x": 0, "y": 0 }, "primary": true, "rotation": 1 }, { "enabled": true, "id": "e3b4a3bbaf4df6f291809d6d5d2bce62", "metadata": { "fullname": "xrandr-DELL 2001FP-C08815B706AL", "name": "DP1-2" }, "mode": { "refresh": 75.024673461914062, "size": { "height": 1024, "width": 1280 } }, "pos": { "x": 1280, "y": 0 }, "primary": false, "rotation": 1 } ]
After a few reboots, the behaviour has become a bit clearer. Every boot, the monitors come up as 1280x1024. Every 2nd boot, kscreen appears to show a slider for the resolution. Maybe a setting is ping-ponging in a config file somewhere?
A number of weeks have passed without any comment, so I'll add my own :) I use a laptop with the lid closed. It has a 1080p 14" screen, so higher resolution than the old Dell monitors I use. I have 2 setups, but always runs with the laptop lid closed 1) Twin Dell 1600x1200 monitors 2) Single Dell 1920x1200 monitor In both setups, the monitor(s) come up in a lower resolution than native. It feels like there is some scaling code than is compensating for a mixed resolution setup that isnt: 1) Realising that the laptop is closed so doesn't need to adjust scaling 2) Scales in the wrong direction - the higher resolution display should be scaled, not the lower. In the meantime I fix every boot using ARandr as Kubuntu repo has removed xrandr
Edit - changed version to 5.4.3, although 5.4.1 and 5.4.2 also showed this behaviour
In >Startup and Shutdown>Background Serivces> untick "KScreen2" and reboot.
(In reply to e8hffff from comment #4) > In >Startup and Shutdown>Background Serivces> untick "KScreen2" and reboot. Hmm, that makes it worse. As plasma crashes every login, it leaves me with a mostly useless desktop. Thankfully krunner still works so I could easily revert by launching "System Settings" again
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 add a comment with the output of `kscreen-doctor -o` and change the status to CONFIRMED. 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!
