Add tablet definition for Huion Kamvas 13 (GS1331)

[blzq]

sysinfo: linuxwacom/wacom-hid-descriptors#247 (comment)

Similar issues to #361 in that the USB identifier is shared with the Huion H950P, so I had to edit that tablet definition locally to not match in order for this one to take priority.

merged, thanks!

Chiming in here -- I manually installed this (and removed the H950P file), and it wasn't working. Looking at libinput record it looks like the tablet was identifying itself as "Tablet Monitor Pad" and "Pen", not the names given in this PR's files.

Not too sure if this is something I've done somehow, but in case anyone else with a Kamvas 13 runs into it, I had to take this PR's file and edit the DeviceMatch line to be as follows:

DeviceMatch=usb:256c:006d:Tablet Monitor Pad;usb:256c:006d:Tablet Monitor Pen

With that change I'm able to see the device in GNOME Control Center, though I do get the following output from libwacom-list-local-devices:

# libwacom-list-local-devices
/dev/input/event21 is a tablet but not supported by libwacom
/dev/input/event20 is a tablet but not supported by libwacom
devices:
- name: 'Huion Kamvas 13'

  bus: 'usb'
  vid: '0x256c'
  pid: '0x006d'
  nodes: 
  - /dev/input/event18

Here's what I see from libinput record for reference there:

/dev/input/event18:	Tablet Monitor Pen
/dev/input/event19:	Tablet Monitor Pad
/dev/input/event20:	Tablet Monitor Stylus
/dev/input/event21:	Tablet Monitor

Hi,
Excuse my ignorance, but could you tell me which file do I have to edit in order for the tablet settings to show up on gnome-control-center? Gnome is updating to v45 on Arch and now, after every login, movement is set to absolute and I have to change it back to the Kamvas 13 screen with the "xinput map-to-output 20 HDMI-A-0" command.
Also "dconf list /org/gnome/desktop/peripherals/tablets/" returns 2 entries, not sure if that's correct, and they are:
056a:033b/
256c:006d/

Thanks!

The file on Arch Linux is located at /usr/share/libwacom/huion-kamvas-13.tablet, I would recommend just editing the DeviceMatch line to DeviceMatch=usb:256c:006d unless you have another tablet with the same ID connected at the same time.

Not sure if it will solve your particular issue though.

Well, it did solve my issue! Thank you very much, kind Internet person <3
Tablet shows up again on gnome-control-center and I can finally map it to the tablet monitor, no more running commands after log in to stop absolute positioning across 3 monitors.
Easy steps

• Comment out the original line
• Add yours
• Reboot
• Profit!

Here is how it looks like now, the USB ID's are the same:

#DeviceMatch=usb:256c:006d:HUION Huion Tablet_GS1331 Pad;usb:256c:006d:HUION Huion Tablet_GS1331 Pen
DeviceMatch=usb:256c:006d:Tablet Monitor Pad;usb:256c:006d:Tablet Monitor Pen

Also libwacom-list-local-devices command successfully detects the tablet, before editing the file, it returned that nothing was supported yet it still worked the mapped buttons, the pen movement and pressure on krita:

/dev/input/event15 is a tablet but not supported by libwacom
/dev/input/event3 is a tablet but not supported by libwacom
/dev/input/event2 is a tablet but not supported by libwacom
devices:
- name: 'Huion Kamvas 13'
  bus: 'usb'
  vid: '0x256c'
  pid: '0x006d'
  nodes: 
  - /dev/input/event14: 'Tablet Monitor Pad'
- name: 'Huion Kamvas 13'
  bus: 'usb'
  vid: '0x256c'
  pid: '0x006d'
  nodes: 
  - /dev/input/event13: 'Tablet Monitor Pen'

Thanks again!
