My Samsung Galaxy Book 10.6" has an issue on Linux based OSes (Ubuntu 17,18,19, Debian and ChromiumOS) where the digitizer (touch screen input) does not match the display - tapping the top right corner will trigger an action on the bottom left, for example.
On regular Linux distros (such as Ubuntu where I did most of the troubleshooting) this is fairly easy to fix as I can use xinput to change the rotation matrix of the digitizer, but I am using ChromiumOS which does not use X (it uses freon instead)
I've tried adding
GRUB_CMDLINE_LINUX="fbcon=rotate:1"
to my startup parameters but that doesn't seem to have any effect on any of the OSes I've tried.
