4 years ago Pointing you to this is the best I can do right now: https://docs.microsoft.com/en-gb/previous-versions/windows/apps/dn440593(v=win.10)
The matrix is a "3x3 matrix" which the accelerometer readings are multiplied by so for example: accel reading: x = 0, y = -256, z = 0 matrix: 1, 0, 0; 0, 0, 1; 0, 1, 0 corrected reading: x = 0, y = 0, -256
I couldn't find better example on how to do this right now, sorry.

4 years ago Some notes for myself:
KaTex syntax for rotation matrix:
\left[ {\begin{array}{ccc}
x & y & z\\
\end{array} } \right]
*
\left[ {\begin{array}{ccc}
x & y & z\\
x & y & z\\
x & y & z\\
\end{array} } \right]Gitlab KaTeX support: https://gitlab.com/gitlab-org/gitlab/blob/master/doc/user/markdown.md#math

Which 0 or 1 does what?
sensor:modalias:acpi:SMO8500:dmi::svnASUSTeK:pnTP500LNG: ACCEL_MOUNT_MATRIX=0, 1, 0; 1, 0, 0; 0, 0, 1
Like what does the first 1 do? the second? normal, left, inverted, right?
I cannot find anything online to tell me which "switch" does what?
The reason for asking is my screen is rotated 90 degrees to the right when i log into Arch Linux (Plasma) and i want to correct this and then make sure all other rotates function as they should.
When i have it set as above the screen rotation on login if normal but not all rotations work.
Ok i got all correct rotations working with this: sensor:modalias:acpi:SMO8500:dmi::svnASUSTeK:pnTP500LNG: ACCEL_MOUNT_MATRIX=0, 1, 0; 1, 0, 0; 0, 0, 1
but my touchscreen and touchpad are inverted so they are pretty mush unusable. Do any of the ACCEL_MOUNT_MATRIX=0, 1, 0; 1, 0, 0; 0, 0, 1 control these items?
