Hello to you all,
after a recent update I have the problem, that I cannot change the display resolution of the internal display (4k) of my laptop anymore.
In my set-up I am using the built-in display (4k) and two external displays (full-HD).
I’m on Cinnamon and the system is up-to-date.
Until recently I could change the resolution of the built-in display to 1920x1080 (same as the external displays) to have the same “experience” on each displays. I had no issues with it so far.
After a recent update I encountered very unusual issues with the scaling of several programs and reduced performance overall (everythings seems laggy, and the screen resolution is bad).
I checked the display settings and, as mentioned above, I cannot change the screen resoltion of the build-in display anymore (it’s greyed-out, I still can change the resolution of the external displays).
When I (de-)activate the built-in display I encounter some weird behavior of the screen resolution as shown below.
I hope that you can help me with my issue.
Let me know, if you need anymore information from me.
First some infos from inxi:
$ inxi -G
Graphics: Device-1: AMD Cezanne [Radeon Vega Series / Radeon Mobile Series] driver: amdgpu v: kernel Device-2: Chicony Integrated Camera driver: uvcvideo type: USB Display: x11 server: X.Org v: 21.1.8 with: Xwayland v: 23.1.2 driver: X: loaded: amdgpu unloaded: modesetting dri: radeonsi gpu: amdgpu resolution: 1: 1920x1080~60Hz 2: 1920x1080~60Hz 3: N/A API: OpenGL v: 4.6 Mesa 23.1.3 renderer: AMD Radeon Graphics (renoir LLVM 15.0.7 DRM 3.52 6.3.9-arch1-1)
The resolution according to neofetch with deactivated built-in display (two external 1920x1080 displays):
Resolution: 1920x1080, 1920x1080
→ Here everything works just fine
The resolution when I activate the built-in display:
Resolution: 3840x2160, 3840x2160, 3840x2160
(still 4k built-in and two full-HD external)
