Not working for TM420IA-EC216T

[vmario89]

Hi,
thanks for providing that repo. I installed it properly but on my device it does not work with recent Kubuntu 40 LTS. I tried different things for hours and have no clue what to do. There seems to be no solution on the web, but a lot of threads of people who tried to solve.

Installation of this repo ok:

git clone https://github.com/asus-linux-drivers/asus-accel-tablet-mode-driver
cd asus-accel-tablet-mode-driver
./install.sh

Debugging says it does not find a sensor:

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

2024-07-05 10:22:00,694 ERROR    Can't find accel sensor (code: 0)

Messing around with kernel parameters in grub did not change the behaviour:

is there any idea how to get that running?

[Talung]

I am getting same issue with Asus Vivobook Flip TN3402Y (Ryzen 7 7730U) chip. Tried all the tests you have with same results. I am running linux and an NVME card off the USB C port, until I get it working the way I want, so am switching between, windows and ubuntu 24.04.

But still no solution that I can find.

EDIT:
Ok, some interesting thing.. I booted up on windows removed the "fast start" option, rebooted twice, then into linux and now monitor-sensor is actually giving me the orientation of the accelerometer!

EDIT AGAIN!:
I spoke too soon... installed the accel-tablet mode driver, rebooted and its gone.
