XP-Pen Deco 01 V2 Support

[sinsixin]

I have an XP-PEN Deco 01 V2 https://www.xp-pen.com/product/461.html on a desktop with Arch Linux kernel 5.4.8

Currently, it has an odd rotation on different boots. Drawing up makes the cursor go right. Drawing right makes the cursor go down. Down->Left. Left->Up. Unplugging then replugging the tablet makes sure the problem occurs, even if it was rotated correctly on boot.

The lower pen button does a middle click.
The upper pen button does nothing. Shows up in evtest, nothing when tapping the box in xev.

Pressure sensitivity and tilt work out of the box.

I would like report an issue too: I am using Kernel 5.3.18_1 on Void GNU/Linux, for me too, the upper stylus button is not assignable under xf86-input-wacom.
I am using the newest (V9 I think) digimend kernel drivers, installed via dkms on one system and via a Debian package on Ubuntu.
The rotation is correct, and I can even set the Scaling/Proportions via the kcm-wacomtablet settings module.
What doesn't work however, are the frame buttons.
I can see them, and they register, when using the xf86-input-evdev driver, but under xf86-input-wacom they just won't show up.

EDIT: I am of course having this issue with the exact same model of tablet, the XP-Pen Deco 01 V2.
I have not yet tested the tilt detection, as I was occupied with the frame buttons.

Should I open a new issue for this?
As far as I understand xf86-input-wacom is the way to go, and I would rather use this than evdev, since it also integrates better into the general settings.

I guess this is redundant with sinxsin's files in a way, but here it is already ready to be integrated into the digimend.github.io remote repository, so I guess it's an improvement.
Here are the information files, pictures and diagnostics of the XP-Pen_Deco_01_v2_revb which has another vid:pid than the already existing model of the same name.
XP-Pen_Deco_01_v2_revb.tar.gz

I included a few comments in the files, I hope it doesn't disrupt anything, but as far as I could tell, when I got it running once in a local repo, it all displayed correctly.

thinking of purchasing this tablet, on linux im mainly just going to jot down math equations(maybe learn to draw later), but is this working on sway(i3 on wayland)? should i purchase something else? do the drivers on their site work?

[jestarray]

alright so it works if you run and configure the official driver application: https://www.xp-pen.com/download-440.html
sadly it doesn't run on wayland(sway), only x11

Just playing with one of these whilst in lockdown. Adding the device arrays into rdesc.c and mine's also working nicely with tilt even.
Although at the moment also not having luck getting the top button to work.
I'll clean up my changes and submit it (I couldn't see an existing fork/pull request?)

Simple in the end, just needed a mapping in /etc/udev/hwdb.d/10-xppen.hwdb
evdev:input:b0003v28BDp0905*
KEYBOARD_KEY_d0045=332

Not sure about frame buttons, with evdev mappings them to 0x100->0x107 they map to mouse buttons, shift<-, shift->, etc but don't seem re-mappable through the xwacom gui.

[ihewitt]

Ok buttons and tips working ok with the combination of
10-xppen.hwdb.txt
in /etc/udev/hwdb.d and
xp-pen-dec01.tablet.txt
in /usr/share/libwacom
(minus the .txt obv)

[jestarray]

@ihewitt will your patch work make the tablet work on wayland?!

[ihewitt]

If it simply requires a working kernel module rather than some sort of X hook interface then I'd assume so, but I have no experience of wayland personally.

Hi @ihewitt - great work with this!
Sorry to pick your brains, the pen works , but my frame buttons do not.

I have placed your 10-xppen.hwdbin /etc/udev/hwdb.dand xp-pen-dec01.tabletin /usr/share/libwacombut I am still at a loss.

I believe I have enabled the Wacom driver by editing
/etc/X11/xorg.conf.d/50-tablet.conf

Section "InputClass"
    Identifier "Tablet"
    Driver "wacom"
    MatchDevicePath "/dev/input/event*"
    MatchUSBID "28bd:0905"
EndSection

xsetwacom list is successful, so I think that has worked

[mrm@mrmp50 ~]$ xsetwacom list
UGTABLET 10 inch PenTablet Mouse touch  id: 9   type: TOUCH     
UGTABLET 10 inch PenTablet Mouse pad    id: 10  type: PAD       
UGTABLET 10 inch PenTablet Keyboard pad id: 11  type: PAD       
UGTABLET 10 inch PenTablet stylus       id: 17  type: STYLUS   

Any pointers would be greatly appreciated - thanks!

Hi, sorry a bit busy at the moment - just wanted to check, you're also running with either the version from https://github.com/ihewitt/digimend-kernel-drivers or with the changes from #375 applied?

[MalcJPM]

@ihewitt - No problem!

You're right to ask that - I was tinkering yesterday, and realised my error there - so I uninstalled everything and installed your repo.

Just so I'm clear - do I need to have the /etc/X11/xorg.conf.d/50-tablet.conffile as I listed?

I've no replaced that, and the keys are working now in evtest... and the Wacom Tablet Finder now registers the button presses. However, the Wacom Graphic Tablet GUI no longer shows me the tab to alter their actions.

I see that you mention not being able to set through the gui - but I was unsure if this was fixed through your later edits?

I'm going to have a play with xsetwacom now - fingers crossed!

[MalcJPM]

Right ho - I think I've got this, cheers for your work!
Not sure if this was a superfluous step, but I used the tablet finder GUI to map through the buttons?

I can set the frame buttons now through xsetwacom- not the GUI.

xsetwacom listshows:

[mrm@mrmp50 ~]$ xsetwacom list
UGTABLET 10 inch PenTablet Keyboard pad id: 9   type: PAD       
UGTABLET 10 inch PenTablet Pen stylus   id: 10  type: STYLUS    
[mrm@mrmp50 ~]$ 

For example I would use:
xsetwacom set "UGTABLET 10 inch PenTablet Keyboard pad" button 1 key ctrl z
to set button 1 as ctrl-z

I'm just reading up on making these binds persistent through xorg.conf.

As I say, thank you for working on this. This arrangement is far more preferable to the XP-Pen linux driver.

[ihewitt]

superb, yeah I'm not 100% sure if the button mappings should be different to work without the hwdb stuff, need an expert to chime in. :)
On my setup I'm just using the kde tablet config app, which just does that xsetwacom mapping under the hood on startup.
