Issue
I am running cachy OS with KDE Plasma Version 6.7.2
I have a three monitor setup that is causing alot of issues.
- If I run each monitor individually it they each work fine. This setup also works in windows.
- If I run the AOC and Samsung together they are fine, but when I plug in the MSI it locks up my entire OS. Sometimes flashes, sometimes KDE completely crashes.
I am not sure what logs to look at or what to try any help would be greatly appreciated.
I did try this from another post:
journalctl -b | grep -i "nvidia-modeset\|EDID\|failed
(I do realize I do not have an nvidia gpu but thought it might tell me something)
The first line of the log says this:
cachyos kernel: amdgpu 0000:2f:00.0: amdgpu: [drm] Failed to setup vendor infoframe on connector HDMI-A-1: -22
The native resolution for the Odyssey Neo G9 is 7680x2160. When I plug in the third monitor it freaks out at this resolution. I think because it puts the default arrangement with the screen to the right? (I have seen on some of the troubleshooting I have done that it tries to put the position of the third screen at the lowest integer number possible which might cause the graphics driver to crash?)
If I down the resolution to 5120x1440 the screen pops up and then I am able to arrange the screens and things work correctly. Now that I have them arranged correctly if I try to put the Samsung back at the native resolution (7680x2160) the default kde panel on the MSI monitor and Samsung disappear (they are offscreen where I cannot see it anymore).
Both the AOC and MSI run at 2560x1440
For an example the screens are layed out like this.
Screen 1(AOC)-----Screen 2 (MSI) [Top]
-------Screen 3 (Samsung)------- [Bottom]
Is there anything I can do to get all monitors running at their native resolutions?
