What happened?

I noticed a couple of bugs while trying out this very promising program on my linux device.
I noticed that my surface pen is not working when trying to draw, but erasing and selection etc works fine.
When doing the pointer test in the settings it recognizes my pens tip as Input 1, but does not recognize any pressure (pressure is constantly 0). I believe this might be the reason for why drawing does not work with the pen.
Moreover I noticed that the pointer test doesn't recognize the eraser at the back of the pen (Input number is 1) and that the functional button on the pen is recognized as 4 when hovering over the device and as 5 when touching the device with the pen. This makes it impossible to map them, because in the settings its only possible to map 1 and 2.

Other programs (rnote) recognize the eraser correctly.
Im using a surface device with the linux-surface kernel installed. Maybe this problem only appears on linux-surface devices.

Sadly, the first issue looks like a known bug, see #238.
The mapping of button 4 and 5 looks just like a small enhancement which i could add.
(kTertiaryButton is 4).
5 is when both 4 + 1 (kTeritaryButton + primary button) was clicked...

Btw: Which type does it say on the pointer test when touching with the stylus?

For me, the pen also works like before (i.e. everything except writing with the pen tool) when enabling pen only input.
The pointer test also says pen correctly, when I use the pen.
The fact that the pen input only doesn't work for the drawing tool feels like its maybe unrelated to the issue you mentioned.

Quick question: does the button value ever be 0 when having the pen on it?
Otherwise i would just remap the settings a bit that pen input = 1, first button = 2 and second button = 4

fixed in 2.2.1-rc.1,
I use now bit masks instead of == (it's okay if you don't understand this :)), this should improve multi button handling and i'm now priorizing the secondary button over the primary button.

Thank you very much for the quick fix. It will be implemented in the nightly build soon, right? Ill test it out then.

Quick question: does the button value ever be 0 when having the pen on it? Otherwise i would just remap the settings a bit that pen input = 1, first button = 2 and second button = 4

No, the input is only 0 when the pen doesnt touch the device.

Yes it will be available in the next nightly Version next Monday with many other fixes.

That's good, then you don't need to change any settings and it will work out of the box in the next nightly.

Hello
I ran into the same problem with the pressure of the pen.
In the test it gets recognized but the pressure is 0.
Laser and other stuff however work.
I am on Version 2.2.1 stable

@CodeDoctorDE

yeah it's already known here #238

Isn't there any solution yet?

@CodeDoctorDE

Sadly not. Its an issue by the library Im using to capture the input

@Postboote1

oh okay
thought i could use it instead of Rnote

Would it be possible to include an option like "disable pen pressure recognition" which would always set the pen pressure to 1, i.e. overriding the detected pressure (which is always 0)?
Is that a possible workaround? I think this would make it possible to still use butterfly, even if the pressure isn't recognized.

@CodeDoctorDE

It should already be possible, then it just "simulate" the pressure. If you have issues, feel free to report it

Yeah, i tried version 2.2.3, but the pressure of my stylus isnt simulated to 1, so the pen doesnt draw.
I use kubuntu 24.04.

@CodeDoctorDE

Hmm, is it a specific value? Can you try the pointer test and write me the values?

WarreTh commented Jan 8, 2025

On the desktop app:

But the mouse also show 0 pressure on the desktop app, but it still draws

On the webapp:

@CodeDoctorDE

Hmm but it looks good...
The pressure should be between 0 and 1...
Im currently not sure how to test it... i currently dont have a linux stylus laptop.
Can you send me a video how it looks like if you draw something?

WarreTh commented Jan 8, 2025

I forgot to say that i use a normal linux hp device, with an xppen tablet connected. I have the official xppen drivers installed.

@CodeDoctorDE

Yeah, it looks like it should work. I use the same values as in the pointer test. If the values there is correct, it should work.

  • Using the select tool works

  • Using the draw tool doesnt

What should i try, can i export logs or something ?

@CodeDoctorDE

It would be nice if you could try to record the screen so I can look what happened.
Logs aren't available.
It would also be useful if you could upload the .bfly file so i can see if the data is correct

When i try to save the bfly file, the application just freezes

Here is when i try to draw:

Hmm, can you try visiting ~/Documents/Linwood/Butterfly/Documents and try to find the file there?

I have no such directory

Is there no linwood directory inside your documents folder?

Nope

Hmm, can you try to close the note, and export the file from the home screen?

The application also freezes when i click the home button after drawing with my pen

How did you install Butterfly?
Did it save? Then you could just go to home without drawing

@WarreTh
Copy link

WarreTh commented Jan 8, 2025

I installed it using flatpak.
I think it didnt save, because i dont find that file.

@CodeDoctorDE
Copy link
Member

hmm, now it's really tricky for me to reproduce it...
Can you try installing the app without flatpak and try to run it?

I installed it using the deb file, and i get the same bug.

Then i tried running the appimage and i got this error:

@CodeDoctorDE

I have no more ideas right now, can you also try the portable version (or the alternative portable version?).
It looks like it has something to do with glibc, can you see which version do you use?

it looks like the problem isn't really related to flutter: SeaDve/Kooha#283

WarreTh commented Jan 17, 2025

I tried the alternative version and get this error when trying to draw with my stylus

Same thing here ! Working fine in other apps,
The stylus is in and on itself working because I can select stuff, just not draw (and erase ?) with it.
