I post this information both as a set of notes to my future self but also in an effort to assist others who may be struggling with the same problems. There are hundreds of posts across the internet about setting these up but much of the information is fragmented or outdated. Anyone who has worked with these can tell you they can be a struggle to get up and running. These touch display controllers have been used for over a decade by a variety of manufacturers. In the X environment I couldn't see any event (no way to move the cursor) because input events are handled by libinput, that fails to recognize my touch events because they are not compliant with some criteria it is expecting.I spent the last few days rebuilding a car pc using an eGalax touch screen and Ubuntu 21.04. S: Sysfs=/devices/platform/soc/b/usb1/1-1/1-1.3/1-1.3:1.0/0003:0EEF:0001.0001/input/input2Īnd with the help of evtest I can see that only event1 is producing understandable events. Then I launched the installation script provided with the driver, and I can see that a virtual device appeared. I downloaded the lastest kernel sources available (4.14), configured as required by the instructions, recompiled and installed the kernel.

I downloaded the driver and the installation instruction from the vendor: Conversely event3, that should be the finger (multi)touch recognition, doesn’t trigger any event whatsoever. Using the program evtest I can see that event2 (that is the pen or stylus touch recognition) works properly (but X Window server doesn’t take any input). Code: Select all I: Bus=0003 Vendor=0eef Product=0001 Version=0210
