KDE Connect: How do I use the "Use as drawing tablet" feature?

Help

Hello!

I just started using KDE Connect and am blown away by the virtual input and ease of use!

However, I could not figure out how the “Use as drawing tablet” plugin is supposed to work. When i activate it on my phone, I can drag my finger across the screen but I receive no feedback on my desktop. I tried opening the Plasma Tablet Tester or Krita, but nothing happens. I also could not find any documentation online.

If someone knows how it works I’d be happy to know, it sounds like a useful feature! :slight_smile:

Thanks!

I am also looking for same info, any progress?

KdeConnect on the PC → setting and enable ‘use as drawing tablet’; do the same on the phone/tablet. The you should get a tile saying ‘use as drawing table’ in kdeconnect phone side. If you use you finger, you contact drawing surface and then with your other hand hold the ‘pointer hand’ on screen and you can draw. Tested using gimp – nothing else was needed.

I debugged this with ADB/logcat and the desktop KDE Connect logs. The Android app was receiving S Pen input fine, including coordinates and pressure:
DigitizerPlugin: ToolEvent(... tool=Pen, x=..., y=..., pressure=...)

But KDE Connect Android then logged:
Tried to send an unsupported packet type kdeconnect.digitizer to: <desktop>

So the tablet/drawing input was not the problem. The desktop KDE Connect version did not advertise support for `kdeconnect.digitizer`.

On my Debian 13 system, KDE Connect 25.04.2 only had the older desktop plugins like `kdeconnect_mousepad.so` / “Virtual input” and `kdeconnect_remotecontrol.so`, but no `kdeconnect_digitizer.so`. Remote Input worked, Drawing Tablet did not.

It looks like the required desktop digitizer receiver only lands in KDE Connect 26.04+. So if Drawing Tablet does nothing but Remote Input works. Check whether your desktop KDE Connect package includes the digitizer plugin and supports `kdeconnect.digitizer`.
