Ubuntu 22.04.4 LTS x86_64, 80VV Lenovo MIIX 720-12IKB, My tablet cannot touch anymore #424

I have installed input-wacom version 1.2.0 because the stock kernal would make the touchscreen buggy (example : touch sometimes will not register, will have 'ghost' input). When I reboot the device, the touchscreen seems to not working anymore. When I check the version of the kernal driver: grep "" /sys/module/wacom*/version the output is : v2.00-input-wacom which is weird

Also, when I try to troubleshoot the problem: sudo rmmod wacom sudo rmmod wacom_w8001 sudo modprobe wacom sudo modprobe wacom_w8001 The output is: rmmod: ERROR: Module wacom_w8001 is not currently loaded

By the way, the name of the touchscreen is Wacom ISDv4 5099

I built and installed 1.2.0. And I got v2.00-input-wacom too. We need to look into that version number issue. But, your driver was built properly. Please try:

sudo rmmod wacom sudo modprobe wacom (or sudo insmod 4.5/wacom.ko)

to see what happens. You do not need wacom_w8001.

Since you are using a Lenovo laptop, I feel it is most likely not a driver issue.

Sorry for late report. But I have found the solution for the problem, which is dirty screen. Unfortunately the screen is prone to ghost touch and/or unresponsiveness if the screen is dirty.
