I have a morphius Lenovo C13 Yoga with coreboot UEFI and Pop os 22.04. I ran WeirdTreeThing’s script but I have no speaker audio, although the headphone jack works. Also the screen orientation is flipped 180 degrees. Has anyone else come across these problems or have any suggestions on what to try to fix? Is there another distro that might work better? Thanks
I switched to Ultramarine/Gnome which has solved all of these problems. The only problem I have found in Ultramarine is the stylus not working correctly in alternate orientations per the post install Chultrabook docs. These files resolve the stylus orientation problem for this tablet.
