Dual link DSI pannel display issue Huawei Matebook E 2022
Hello, I have a problem with kernels newer than v6.1.4. For some reason, my screen splits in half (when I rotate the screen, the split and orientation does not change).
I got the kernels directly from here: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/refs/tags
This problem occurs with every Linux distribution I have tested.
Arch, Manjaro, Debian, Ubuntu, Fedora. Even without a display server, the error occurs in the console. Therefore, I think it must have something to do with the framebuffer.
I made Video from by now:
For example, whenever the cursor flashes, the image on the left side of the monitor moves up and comes out at the bottom. Sometimes the right site does it as well, but not as often.
It is difficult to describe... A good example would be a toothed belt that you hold tight, and a motor tries to turn anyway. It's exactly the same kind of jerking with the picture.
It is interesting because it only occurs to a certain degree and does not go around like a conveyor belt. Sometimes one of the sites turns black first during poweroff or startup.
For testing, I use Fedora.
My hardware is a Huawei Matebook E See:inxi_output.txt
Unfortunately, for some reason I can't dump my VBios as I get an error that it is an invalid argument. https://www.intel.com/content/www/us/en/docs/graphics-for-linux/developer-reference/1-0/dump-video-bios.html
I also built a kernel as described here, using the default kernel from fedora 38. The kernel is v6.2.9-300. fc38. x86_64. This shows the same error. https://www.intel.com/content/www/us/en/docs/graphics-for-linux/developer-reference/1-0/build-guide.html Picture of the Screen v6.5.0-rc3+:
I'm sorry for the quality, but I can't get it better

For sake of completeness, here is the bug report I had made before it was suggested that I should report it here. https://bugzilla.kernel.org/show_bug.cgi?id=217666
I'm still learning how all that works, so please send some links to or manuals where I can get some more Background knowledge.
