[kwin] [Bug 403438] External monitor connected through displayport <-> HDMI is not detected in Plasma Wayland
https://bugs.kde.org/show_bug.cgi?id=403438 --- Comment #5 from Dan G --- I discovered that the two USB-C ports I was using to plug in the monitor might have problems. They are both part of the same board, and I suspect that the board is damaged in some way. When I plugged in the monitor to the ports on the other side of the laptop, it worked as expected in the Wayland session. I don't know why KDE on X was able to use the external monitor, but I have a theory. I discovered that the USB-C ports that I was using originally might have a problem because I was unable to output sound over HDMI. However, when I tried the ports on the other side of the laptop, the sound output worked fine. My theory is the the wayland session is depending on something to do with sound output, and when that fails it then won't output the video. But on KDE on X, it will happily output video regardless of sound. This is very much just a theory based on what I have observed. But my feeling is that this really isn't a bug but a hardware problem with my machine. I thought I would include the additional information in case it was of interest in some way. Please feel free to close this issue. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=403438 --- Comment #3 from Martin Flöser --- According to the log you have both an Intel and amd gpu. Do you know which one is connected to your USB port? I assume it's the amd one. -- You are receiving this mail because: You are watching all bug changes.
