Description Benjamin Tissoires 2017-11-10 09:52:28 UTC
Description of problem:
The Dell Canvas 27 ( has an external tool known as the "Totem".

It is a new type of devices, as it is meant to be used by the system (like the Pads of the tablets), and should pop up some menus placed around the tool itself.

Basically all the input stack needs to be updated (kernel, libinput, wayland-protocol, mutter). Adding tracking bugs so we can include those in Fedora.

Preliminary patch, to be submitted upstream

hid-recorder of a drop of the totem (not perfectly flat) which outputs both spurious events on the touch interface and then correct events on the totem interface.

evemu record of the previous hid recording of the totem input node

evemu-record of the previous hid recording of the touch input node (with the unwanted events)

Doing some pruning, did these get picked up?

Comment 6 Benjamin Tissoires 2018-04-10 15:11:42 UTC
Still waiting on upstream work. There is a heavy lifting required in hid-multitouch/hid-core and I never had the chance to finish the job.

Hi Benjamin, I developed an e-learning platform on top of the Dell Canvas 27. It currently runs on top of Windows 10, but I would like to port it to Linux.
I don't care much for the Totem, but I need at least the digitizer to be working.
Can you please help me to get it working on Linux? I understand that it will require some kernel/userspace patching, but I didn't find any updated instructions about what I need to do.
I'm currently forced to use 4.20-rc1+ because of an amdgpu bug.
