ODROID-C2 Ubuntu Mate: multi-touch (zoom in/out) not working

Unread postby linbrown » Sat Mar 10, 2018 1:01 pm

I just bought ODROID-C2 board, and want to configure it into the kiosk mode with Ubuntu 16.04.3 Mate (https://odroid.in/ubuntu_16.04lts/). Everything works fine except that multi-touch zoom in/out actions do NOT work. Single touch and move actions work. The problem is not a hardware problem since zoom in/out actions work if I install Android on the board. Also If I followed "How to update the kernel and system" section in https://wiki.odroid.com/odroid-c2/os_images/ubuntu/v2.4, the system gets corrupted.

Really appreciate any helps. Thanks in advance!

Can you share the VID/PID of your touch module?

Try Chromium browser.

Thanks for the replies!

It is interesting that Chromium browser works. But Firefox does NOT, either the application I need to run. Does this mean that the kernel driver for the touch screen is fine? Why does the behavior vary by applications?

I do not know how to get "VID/PID" yet.

Correction: "nether the application I need to run". The application I need to run also does NOT respond to the zoom in/out touch actions. Thanks!

Chromium browser probes that the kernel driver for you multitouch is good. I'm not familiar with Ubuntu Mate, you would google to find a decent solution for your set up. Here few you would read.

I heard very few Linux application software supports the multi-touch feature.
In fact, I knew only the Chromium can handle the multi-touch input events.

It is the main reason why most digital signage and educational blackboard companies are using Android instead of generic Linux desktop.
