Wanting to use an XP-Pen Tablet in KDE under wayland


I just got Garuda linux (KDE Dragonized Gaming Edition) installed, and my drawing tablet I'm attempting to see if I can get working under wayland is the XP-Pen Innovator 16. I Installed the xp-pen-tablet package from the AUR via the paru package manager, and if information about the specs of my computer is needed it's located in the screenshot below. One last thing that the screenshot won't inform you however is that I'm also running a dual monitor setup.

Basically my issue is that my stylus is incorrectly proportioned to my tablet screen causing it to be offset and severely misaligned from the actual pointer's location whenever I try to draw on the screen. This problem doesn't exist on X11 (though there are other crippling problems X11 currently gets me), and it also seems to go away if I use solely my xp pen tablet as the only monitor/screen and don't connect my second monitor? But on wayland at least, if I run it with both monitors, that causes the incorrect proportion/offset problem with my stylus and the pointer on the screen.

(I'm willing to record this problem and post as gif if you feel that'll help as well)

Is anyone else running an xp-pen tablet on arch with a setup similar like mine on wayland (plasma)? Or even happen to use the exact same tablet I'm using with this setup, and experiencing any problems similar to this yourself? Or is there something I'm missing that I should do to attempt to fix this? I've tried playing around with the xp-pen menu and setting the screen/pen area there but to no avail.

It's a small miracle you can boot to a Wayland session at all with an Nvidia driver. There has been some progress recently, but my understanding is Wayland is still badly supported/broken on Nvidia hardware.

Unless someone chimes in with some advice for lifting the curse from your Nvidia/Wayland combo, addressing these crippling problems might be a better area of focus.

So, when you use a single monitor the tablet is mapped correctly to the single monitor, and when you use two monitors then it is mapping the tablet to the full extent of the two displays?

If so, this should be something configured via the tablet software, where you can choose how it deals with multiple displays.

Of course, if the tablet software doesn't know what Wayland is then the main options are 1) contact the developers and ask for Wayland support and 2) go back to using Xorg.


Wow, so first off I want to say, thanks so much for the really quick response guys! :grinning:

Secondly, at least on this front what I've found is that whenever the xp-pen application I installed from aur is active in the system tray while on wayland, then that's where my pen-being-offset problem in my op starts. Once I exit out of that however, everything is somehow fine with my tablet, the offset is gone and I can write normally (albeit I do notice a bit more of a gap between my pen and the cursor compared to windows, but this is probably more of a calibration issue than anything, and is potentially it's own discussion).

So in short, although I'm going to try and confirm this with xp-pen's support as per SGS's and jonathon's suggestion, my thoughts are that perhaps the official driver from xp-pen is at the moment only intended for xorg and not quite for wayland yet? Although I can't quite answer why it works out-of-the-box when I exit out of the xp-pen application in the system tray?

It's a small miracle you can boot to a Wayland session at all with an Nvidia driver. There has been some progress recently, but my understanding is Wayland is still badly supported/broken on Nvidia hardware.

Absolutely, it's good to keep this perspective in mind, and I appreciate the reminder! I can always fallback to windows if I need something done (which is why I'm super thankful I found an extra nvme ssd lying around in the house going unused on that note!), so this little wayland adventure with nvidia hardware I'm doing I feel I should treat as more of an experiment than anything, and whatever I can do (regardless of how small) to help get better support for people with this similar setup, since I imagine the people working on getting better support need some people to use it and report back.
