Limitations

• This driver identifies tablet mode by accelerometer data which means when is laptop's display almost in the horizontal position it is recognized as tablet mode and does not matter whether is laptop flipped or not

Troubleshooting

LOG=DEBUG sudo -E ./asus_accel_driver.py "default"

Why was this project created? For laptops which do not indicate tablet modes (e.g. Zenbook UN5401QAB or Vivobook TM420 do not send EV_SW.SW_TABLET_MODE or EV_KEY.KEY_PROG2 either) (see the reported issue for Kernel)
