I had the same symptoms. Try the changes to the code I made in pull request 95. It uses a newer Linux API to register the device, and libinput seems happy with it now, so it works in gimp and inkscape.
So I am a complete noob and I am trying to figure out the installation, I installed the app on my device but I don’t understand what I am supposed to download on my PC/how to download it on my PC. Any help would be greatly appreciated
do you have linux?
I am having same problem and no I do my have Linux I’m running windows 8 x86 I’m guessing it’s not compatible with windows
Yes, as stated in the requirements section in the Readme, you need Linux to use gfxtablet. (Would be a good reason to give Fedora or Ubuntu a try )
