eGalax touchscreen is identified as tablet. Doesn't work

[Daniel Swanson]

EGalax touch screen "Pen" is identified (apparently by udev) as a tablet. libinput then ignores the "Pen" and the touchscreen does not work.

*** Part of output from journalctl ***
May 18 13:56:09 BL2-2K /usr/lib/gdm3/gdm-x-session[1082]: (II) event5 - eGalax Inc. USB TouchController Pen: is tagged by udev as: Tablet
May 18 13:56:09 BL2-2K /usr/lib/gdm3/gdm-x-session[1082]: (EE) event5 - eGalax Inc. USB TouchController Pen: libinput bug: missing tablet capabilities: resolution.Ignoring this device.

*** Creating the following udev rules file, fixes the touchscreen for me ***
/etc/udev/rules.d/91-libinput-egalax-local.rules
ACTION=="add|change", KERNEL=="event[0-9]*", ENV{ID_VENDOR_ID}=="0eef", \
ENV{ID_MODEL_ID}=="0001", ENV{ID_INPUT_TABLET}="", ENV{ID_INPUT_TOUCHSCREEN}="1"

*** Note ***
I don't yet know enough about the interaction between libinput, udev and other packages to be sure what the proper long term fix is.

Please help us to progress this issue by reporting it to the libinput developers here:

https://bugs.freedesktop.org/enter_bug.cgi?product=wayland&component=libinput

and then let us know the ID of the new bug.

[Daniel Swanson (dswanson2609)]

It looks like this bug has been previously reported on the libinput database as bug 102632 and they marked it WONTFIX. This touchscreen worked fine with Ubuntu 16.04 (which used evdev), so I am trying to figure out how that worked.

[mike (kc7noa)]

i have the same problem and did work with 16.04

Just came accross this problem with Shuttle X50V6

Adding oem-priority project because it blocks a POS project with Ubuntu for one of our clients.

Sticking with 16.04 raise maintening costs.

[Daniel van Vugt (vanvugt)]

Sounds like we'll just need to carry a workaround patch for it.

One solution is mentioned at the top of this page.

Another solution is mentioned at the bottom of:
https://bugs.freedesktop.org/show_bug.cgi?id=102632

[Michel-Ekimia (michel.ekimia)]

Hi daniel , do you feel this kind of patch ( the one above) can goes in 18.04 ?

[Michel-Ekimia (michel.ekimia)]

I confirm 91-libinput-egalax-local.rules workaround Works.

But touch is not really precise

[Michel-Ekimia (michel.ekimia)]

Also Driver from touch screen Manufacturer works perfectly :

[Daniel van Vugt (vanvugt)]

I don't have any authority to say what can go into 18.04. But anyone can try to get things into 18.04...
