Stylus buttons do not get recognized with certain HP & Wacom pens

[xkevio]

Describe the bug: The two extra buttons on my stylus do not get recognized correctly within Rnote even though they are configured in the settings to either switch to the eraser or selection tool.

When pressing the primary stylus button, nothing happens. When pressing the secondary stylus button, it moves the canvas or rather stops using the brush.

I tested the input with $ libinput debug-events and that seems to only recognize me pressing the secondary button. $ libinput list-devices also does not recognize the extra eraser device whereas xinput does.

The stylus in question is the HP Pen (1MR94AA) and I use the i3-gaps compositor on Manjaro Linux. libinput and libwaycom are installed. Weirdly, the primary stylus button works in Xournal++.

xinput recognizes my stylus as two pointers, one pen and one eraser:

$ xinput

Furthermore, the settings when looked at with xinput list-props [id] look as follows for both:

$ xinput list-props 19

Hi Exactly same problem here. In addition, I have no pressure sensitivity as well. Buttons and sensitivity are working fine in Xournal++.

As described above xinput has an Stylus Eraser but libinput list-devices has none. With libinput debug-events I was nevertheless able to track eraser logs. (see log below)

Behaviour is identical with the BAMBOO Ink Plus and HP Pen (1MR94AA) on my HP Pavillion.

Exactly the same as @schuhva said. No pressure. Panning works using the middle button of my Bamboo Ink (not plus) digital pen. The first button (eraser) does not work, however.

Output of `libinput list-devices`

I assume this is because my Wacom Bamboo Ink pen only gets listed in libinput as one device (not as three separate ones?)

My suggestion would be to add a setting to toggle between using xinput and libinput. Waiting for libinput to fix this seems like a bad idea.

@xkevio Mind chaning the title to "Stylus buttons and pressure do not get recognized with certain pens (HP&Wacom)"?

[schuhva]

Update to pen support: For other reasons, I have installed Fedora 37 with Gnome 43.2 and Wayland, with pressure sensitivity and eraser working just fine. (on the same laptop) On my earlier comment I tested rnote with Linux Mint using Cinnamon desktop with X11. When switching to gnome X11 Session in Fedora, there is no Pressure sensitivity and eraser. Therefore, it is probably a similar or same problem as issues #194

[Quoteme]

@schuhva I can confirm this. On Wayland all buttons work. The problems only arise on X11.

[hcsch]

Not sure if this is the same issue or a separate one, but with my Dell Active Pen PN579X the primary button also does nothing in Rnote, while the secondary button is recognized as the primary one. I have Button 1 set to "Default" in GNOME 44.0 Wayland. libinput debug-events shows me TABLET_TOOL_PROXIMITY events switching between pen and eraser when the primary button on the pen is pressed, and TABLET_TOOL_BUTTON events (331 (BTN_STYLUS)) for the secondary button. The pen works as-intended in the "Test your Settings" panel in GNOME Settings. libinput list-devices shows a Wacom HID 486A Pen. In case it helps, Xournal++ recognizes the secondary button as "Button 2", "Button 1" is not mapped, and the primary button on the pen is recognized as the eraser. Same behaviour as @schuhva has observed with their pen, as far as I can tell.

[jackyohh]

I have Dell Active Pen PN579X too but working on Win10. Almost same beviour like above (@hcsch ). 2nd Button is recognized as Button 1. But 2nd Button is always configured as <temporary - forms>. Can't change this in rnote settings. Dell Drivers are installed and Buttons are configured in "Dell Active Pen" software. Xournal++ is working fine with my Pen.

BTW Rnote is so AMAZING! Clean userinterface with quick handling!! THX dev Team!!!!

[TheOnlyJoey]

I am using a cheap Lab31 'USTP03' pen that has the same behavior, this is on GNOME 46 on Wayland. (ASUS Chromebook with AMD Ryzen 3 7320C running Debian)

In Rnote it just only scrolls, there is no way to do a simple remap in the settings it seems. Xournal and Gimp work properly.

[Doublonmousse]

@TheOnlyJoey This pen is not an active pen so it actually mimics a finger touching the screen (and thus sends touch events, not pen events).

You have to activate draw with touch input to get it to work. It is to note you won't be able to get the full functionality of an active pen with this (no way to get palm rejection or distinguish a touch event from a pen event)
