Tablet palm rejection (programming.dev)
submitted 3 weeks ago by [email protected] to c/[email protected]

I own a ThinkPad X1 Tablet (Gen 2) - but the only thing that matters is that it is just a tablet with a touchscreen and Wacom pen.

When doing handwriting on it (using Rnote) I become very annoyed, because as soon as the stylus loses the hover signal (only about 1.5 cm) the rest of my hand starts moving the canvas. As I tend to pull the pen far from the paper often this is really an issue.

When using Windows for the first time (with Windows Ink) I remember palm rejection working exceptionally well, even without using the pen - it just magically knows that this is part of my hand and not a finger. Also from what I remember any touch that started while the pen was hovering will not be registered even when the pen gets pulled away (you have to stop touching the screen and then touch it again)

Is there any way to improve the palm rejection on Linux (I'm using Gnome with Wayland btw) By the way, is there a way to scroll with the stylus like on Windows? And are there any good handwriting utilities for Wayland (I've only heard of CellWriter but it doesn't work well at all)?

I reported basically this issue a few months back with another Lenovo device. Sadly there was no other activity towards resolving this.

Maybe you can bring in some new information if you can confirm, that you have the same issue.

In essence the hover recognition distance greatly reduces when touch input is present causing these jumps to happen with the palm because when writing any lifting off the pen will reactivate touch.

This sounds like it needs a bounty. If there is nobody paying developers to make Linux work for their artsy stuff, this doesnt work.

Most devs simply dont use tablets as they dont make sense for development. So the normal flow is artsy people pay money, developers do the code.

This is a huge reason why we have nice code editors nut no Photoshop alternative for example. At least I think so.

Mostly speculation:

I think that's just a time and money issue. Blender was behind Autodesk for a long time, but nowadays it's a real alternative that offers extra features.

Gimp, Krita, and other Adobe alternatives are still in that earlier phase where they're not yet good enough to get funding from studios and companies using it.

Yeah possibly. I think the enshittification of Adobe stuff will help here. But calling that software "early phase" is brave, as it had all the time to get established

I mean it's definitely not new software, but I meant it in the context of commercial adoption. Let's hope conversions and money starts rolling in when the gimp redesign comes out.

It's pretty hard to get established if your competition drops millions while you have pennies. Same as Linux Vs win and mac on desktop.

You can already try GIMP beta, only as appimage poorly (or ubuntu ppa, works through distrobox) and report bugs.

It is pretty good, needs better defaults and it is crazy how GTK3 was the one where stuff started to get HUGE.

So you see buttons etc are bigger, not fitting the menus anymore. But it works, and it finally has color profiles and nondestructive filters, which are a base requirement for graphics design.

Nice, but I'll wait on it. I use gimp in the same way I would paint, so it makes no difference to me. I'll definitely start once again annoying graphic designer friends to try it out when it's released.

Perhaps you could try Xournalpp. It has internal palm rejection, which you can configure to keep rejecting for x seconds after you lift the pen from the screen.

Well, I think Rnote has more features and an overall better design. I tried using Xournal++ before and it was missing some features I know from all of the infinite canvas whiteboard style note taking apps

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.
