Yoga C13 screen orientation and audio in Pop OS

Support Linux Support

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.

/etc/libwacom/google-morphius.tablet

I ran into an error trying to do this on Arch, something like:

ValueError: not enough values to unpack (expected at least 3, got 1)

If anyone else like me is having this problem, newer versions of libwacom have changed the DeviceMatch format to use | symbol instead of :.

So in the file /etc/libwacom/google-morphius.tablet, replace the DeviceMatch line with this:

DeviceMatch=i2c|27c6|0ed0
