Automatic screen rotation

[hansen]

I finally did an OS update today. After the last update rotation quit working for me. After this update, it was still broken.

(Unrelated: with the current update, I can shutdown the device with wifi on! Still seems to hang when it tries to sleep with wifi on, though.)

I went through the motions of the original fix:

1. sudo pacman -S iio-sensor-proxy #[was already installed]
2. create /etc/udev/hwdb.d/60-sensor.hwdb

sensor:modalias:*
  ACCEL_MOUNT_MATRIX=0, 1, 0; 1, 0, 0; 0, 0, 1

3. Setting -> Display Configuration: Orientation = Automatic; Uncheck "Only when in tablet mode"

After a reboot, rotation seems to be mostly working.

"Mostly" because I can have it in a horizontal orientation, but if I lay the screen back too far (e.g., resting it against a pillow on the couch), it will change back to vertical orientation. I don't know if more tweaking of the matrix would help with this. But I can deal with it for now.

This is interesting, it changed nothing at my side. The display is always rotated 90 degrees clockwise (but rotation itself works).
