SUMMARY
***
when I try to activate the keyboard backlight with my clevo notebook, the
drivers for the touchpad are going lost.
In standard installation the touchpad works fine.
But when I activate the workaround to activate the backlights, the touchpad
hangs.
The touchpad isn't moving smooth anymore, it hangs. And the gestures (2 finger
to scroll) are not working anymore, two-finger-gestures seems to be deleted
(always until the next reboot)
This occurs especially, when the system goes into susped mode.
After coming up again, the touchpad reacts horrible laggy without gestures.
When I reboot the system, the touchpad works fine, but after suspend mode, the
same behaviour.

***
This is the "modification" I did, after this, the touchpad does not work
properly, everytime I suspend/reactivate it:
SO strange, because without going into suspend, it works, but with suspend it
fails.
These are the commands:

sudo apt install -y git dkms build-essential linux-headers-$(uname -r)
git clone https://github.com/tuxedocomputers/tuxedo-keyboard
cd tuxedo-keyboard/
make clean
sudo su
make dkmsinstall
echo tuxedo_keyboard >> /etc/modules
modprobe tuxedo_keyboard

echo "options tuxedo_keyboard mode=0 brightness=25 color_left=0xFFFFFF
color_center=0xFFFFFF color_right=0xFFFFFF" >
/etc/modprobe.d/tuxedo_keyboard.conf

exit
