Support for the XpPen Artist Pro 19 (Gen2) styluses
A visual overview of the product.
Hi, this is a request to support the XpPen Artist Pro 19 (Gen2) styluses, in the same fashion than the already made support for the XpPen Artist Pro 16 (Gen2) stylus. It's a display tablet with two stylus and a remote pad for the buttons. This thread will not be about the pad, as a thread already exists for the ACK05 Remote : #32 .
What works/doesn't work
The tablet works almost fully out of the box on Debian KDE 12 X11, after setting a X11 rule and a xsetwacom script as I describe on my blog-post for the 16. I'll perform in a later post a set of tests on Wayland Plasma and Wayland Gnome, Fedora 40, because now setup a laptop dedicated to that on my test station.
- Mapping
- Stylus tip and Pressure sensitivity
- "button 2" on both styluses can be customised
- Tilt
- Thick stylus:
- Scroll wheel: can't configure shortcuts associated with it.
- Button 3 is an eraser mode by default (should be a right-click).
- Thin stylus:
- Button 3 is an eraser mode by default (should be a right-click).
Styluses: what works (green) and what doesn't (red).
Observations
Compatibility with the 16:
I can use the two styluses of the Artist Pro 19 (gen2) on my Artist Pro 16 (gen2) connected to my main workstation, and the udev-hid-bpf https://gitlab.freedesktop.org/libevdev/udev-hid-bpf/-/blob/main/src/bpf/stable/0010-XPPen__ArtistPro16Gen2.bpf.c?ref_type=heads fixes the problem "Button 3 is an eraser mode" (but has no effect on the scroll-wheel). If I install udev-hid-bpf (last release) and run the Artist Pro 19 (gen2), it doesn't fix the styluses.
Eraser mode:
Another observation, the two styluses for this model don't have any eraser tips. In this context, it might sounds like keeping the "eraser mode" for Button 3 a good idea; but I would be opposed to that: to operate the system and digital painting software, a "right-click" is more important. Also, digital painting software like Krita can have a shortcut key to switch to eraser mode, and getting the button 3 customisable allows the end user to decide what to put on it.
Scroll-wheel:
I have no idea how this feature can be useful while painting. My first experience was to feel this gadget a bit on my way while holding the stylus. Maybe users will use it to map i and o to manage opacity like a airbrush in Krita? or [ and ] to manage the brush size? or numpad4 and numpad6 to manage canvas rotation? or k and l to change the foreground color value from dark to bright? For sure, it triggers new ideas, and I have to test what could be useful. A good default would probably be a simple mouse-scrolling, imo.
Hid-recorder
The Xppen appears three times in the list, here is a report of all item on the list:
xppen_artist_pro_19__gen2___hidrecord_all_devices_headers.txt
The second item on this list reported activities when I used the styluses. So I recorded it, but because it is a lot of data, I recorded a video as well:
xppen_artist_pro_19__gen2__video_hidrecord
Video while performing the hid-record.
And here is the hid-recorder output recorded during this video:
