reMarkable Tablet Driver

This userspace driver for Linux is able to simulate the real tablet input from your reMarkable Paper Tablet on your PC, with pressure sensitivity.

Demo

demo.webm

Building

You can build the project using CMake:

mkdir build
cd build
cmake ..
make

This will generate the tabletDriver binary in the build directory. Ensure you have libssh and its development headers installed, as well as pkg-config.

Installation

To install the built binary, run:

sudo make install

This will copy the tabletDriver binary to /usr/local/bin.

If you want to change the install location, you can specify it when running cmake:

cmake -DCMAKE_INSTALL_PREFIX=$HOME/.local/bin ..

Then run make install as usual.

Command Line Arguments

Usage: rmTabletDriver [OPTION...]
reMarkable Tablet Driver -- a driver for using your reMarkable tablet as pen
input

  -a, --address=ADDRESS      Address of reMarkable tablet. Default is
                             10.11.99.1.
  -k, --key=FILE             Private key used for authentication.
  -v, --verbose              Produce verbose output.
  -?, --help                 Give this help list
      --usage                Give a short usage message

Limitations

I only tested this driver in KDE Plasma 6.4 under Wayland. It might work on X11, but it hasn't been tested.

Also, I'm not sure if it works on the reMarkable 2 or the Pro. I only have the rm1 to test. If you have an rm2 or pro, you're welcome to try it and submit an issue if it doesn't work.

It is expected you will use plasma settings' (or an equivalent) drawing tablet configuration to get the orientation and the active region right for you.

How does this differ from LinusCDE's and Evidlo's drivers?

First of all, they're both good drivers. I've used both in the past. However, there are two main problems that this fork solves:

• LinusCDE's driver requires two files to be run. One on the tablet itself, and one on your computer. I didn't like having to run two files every time I wanted to use the tablet.
• Evidlo's driver doesn't work on Wayland and probably never will, since it uses Python's libevdev library. There is another uinput library on Python, but I tried using it and the virtual device ends up being ignored, maybe as a safety feature.

Credits

Thanks to LinusCDE for the base of the driver, which this driver is forked from.

Thanks to Evidlo for inspiration on how this driver should operate, and their well documented and very readable code.
