Disable Touch with VU5A

Unread postby dlmutiny » Thu Oct 25, 2018 2:32 am

I would like to disable the touch screen with the VU5A touchscreen running on a C2. I see that there is an option in the boot.ini to disable touch with the VU7. However, when I set setenv disable_vu7 "true". It doesn't work for the VU5A.

Maybe set it to setenv disable_vu5 "true"?

You should be able to blacklist loading the drivers for the touchscreen.

make a file in /etc/modprobe.d

call it
Code: Select all
no-touch-input.conf

and put the following code in it.
Code: Select all
#Do not load the vu5a/vu7a touchscreen input drivers on boot.
blacklist dwav-usb-mt

this should be enough to stop the touchscreen drivers from loading and disable touch input.
