When using any application that accepts pen input via a bamboo ink stylus if the cursor is on one side of the screen and I bring the pen down to touch the screen, the cursor will behave as though I dragged a mouse from where the pointer was to where I placed the stylus down. As shown in this picture: screenshot

I have tested this behavior and it happens in all of the following applications I have tested:

  • GIMP
  • Krita
  • Xournal

It also exhibits behavior similar to the above (dragging mouse across the screen) in the following applications not intended for pen use:

  • Unity Desktop
  • Google Chrome
  • Entire LibreOffice Suite

I have not found or installed Linux drivers for the bamboo ink stylus. It is connected via bluetooth and on the bluetooth menu it is listed as a generic input device. My Xorg configurations are the default for Ubuntu 17.04. Here are my system specifications:

GPU Model: Intel HD Graphics 620 (Kabylake G2)

OS Type: 64-bit

Disk Size: 251.0 GB

Non-default application installs:

  • Krita
  • Gimp
  • Pitivi
  • Google Chrome
  • Oracle JVM 8
  • GCC and Binutils
  • All requirements for the above

This is a bug in the wacom kernel module which has already been fixed in the upstream repository of the wacom-input project.

Commit message for the bugfix

Unfortunately the fix hasn't even made it into Ubuntu 18.04. But fortunately it is straight forward to update the kernel module yourself:

  1. Download and extract the last release of the input-wacom kernel driver from the github page:

    wget https://github.com/linuxwacom/input-wacom/releases/download/input-wacom-0.39.0/input-wacom-0.39.0.tar.bz2
tar xf input-wacom-0.39.0.tar.bz2

  2. Build and install the module:

    cd input-wacom-0.39.0
./configure && make && sudo make install

  3. Reload wacom modules:

    sudo rmmod wacom
sudo rmmod wacom_w8001
sudo modprobe wacom
sudo modprobe wacom_w8001

(Installation instructions taken from https://github.com/linuxwacom/input-wacom/wiki/Installing-input-wacom-from-source)

I did not find the solution myself, but this guy did: https://johnbintz.com/blog/2017-12-31-ubuntu-linux-wacom-pen-prox-click/
