This blog-post is a follow-up post of "How a kernel update broke my stylus... Need help!" published 10 days ago. Please read it if you want to know more about the problem I had with the stylus.

This solution is still W.I.P. and I still have some homework to send more data about my tablets after this blog post, but in overall I'm already using a newer kernel (Linux workstation 6.5.10-200.fc38.x86_64) and I don't have the problem with the eraser mode on the top button of my XPPen Artist 24 Pro and XPPen Artist 16 Pro Gen2 styluses. The buttons are also now perfectly customisable via xsetwacom CLI tool. Yay! That's why I wanted to share this blog-post as soon as possible.

On the mailing list Benjamin wrote me a detailed answer about the whole story. It's very interesting and I decided to copy and paste it here. Thanks again Benjamin! 👍

And that's exactly what happened in your case David. Which is why I'm so happy (also because I fixed the tools from an author I like and already had the books at home :-P):

Really detailed and cool response from the kernel developer. I also found the use of the recent BPF feature to provide a workaround until a proper kernel fix lands really interesting.

That BPF workaround was so cool. I didn't even realise you could write BPF filters in rust now. Thanks for sharing.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
