Touchscreen detected, enabled, but no events

youarefunny · 2016-10-29 20:20:00

Hello everyone, I had a touchscreen that used to work on Arch (last known working is a couple of months ago though) and now it isn't.

I have tried using both evdev and libinput drivers, and both detect the device and configure a bunch of properties but it doesn't work on either. Touching the screen does nothing (including in xev and libinput-debug-events) and I've event tried watching /dev/input/event11 and I get nothing no matter what I do to the touchscreen (as a contrast the device for my touchpad dumps a bunch of stuff when I touch it). I've also tried under both Wayland and X11.

I wonder if anyone has have ideas or suggestions on why this might not be working or other things to try.

I did some more digging and found that even cat /dev/input/event1 doesn't create any output when I touch the screen which seems suspicious.

Hi,

I face the very same behavior.
I guess I miss some kernel package or have a miss config very deep in the Arch OS Core. My trouble with the Touch Pad started when I switched to LTS-Kernel.
I tryed to install snyaptics 'xf86-input-synaptics' and xf86-input-wacom' packages, the configs looked good but still no events recognizable (so I removed them).

The system is up to date everything else work's fine.

I'm afraid that I will run out of ideas soon, I would be happy, about any helpful recommendations how to at least debug the problem.

Thanks for your time in advance.

Here are my settings and findings ...
