Surface Pen support missing when present ootb in Bluefin.

[valerie-tar-gz]

Describe the bug

My Surface pen does not register properly with Bazzite after being connected. Nothing shows in settings about the tablet and no input is recognised as either mouse or pen.

What did you expect to happen?

In Bluefin (39 & 40, gts & latest) the pen works after being connected via bluetooth for the first time as you'd expect. Wacom tablet settings show and allow you to change settings. It lets you use the pen as a mouse on the desktop. Pressure sensitivity works in Krita, using the other end of the pen works as an eraser, the button on the pen works and is bindable, the whole nine yards.

Output of rpm-ostree status

No response

Hardware

Surface Book 2 w/ Surface Pen.

Extra information or context

Brand new install of Bazzite, not updated but I believe it shouldn't really matter.

I additionally tried layering opentablet driver but this did not work, nor did I use it on Bluefin.

@castrojo any idea what you might be shipping to make this work?

[valerie-tar-gz]

I ran rpm -qa on my bazzite desktop and the surface and there seems to be a few surface related packages. However my surface is on bluefin-dx-surface. I'm going to rebase to the non-surface version and see if the pen stops working. If so, might just be something that you could recommend layering, or ship in the image assuming it doesn't conflict with anything else.

[castrojo]

It'd be in here somewhere, but the packages we just added are for libcamera support. Maybe something in the config files?

Upon rebasing to the non-surface image the pen no longer worked

Running rpm -qa | grep "surface" on the bluefin surface image yields: kernel-surface-default-watchdog-6.9.9-1.surface.fc40.x86_64 kernel-surface-modules-core-6.9.9-1.surface.fc40.x86_64 kernel-surface-core-6.9.9-1.surface.fc40.x86_64 kernel-surface-modules-6.9.9-1.surface.fc40.x86_64 kernel-surface-6.9.9-1.surface.fc40.x86_64 kernel-surface-modules-extra-6.9.9-1.surface.fc40.x86_64 libwacom-surface-2.12.2-1.fc40.x86_64 kmod-wl-6.9.9-1.surface.fc40.x86_64-6.30.223.271-51.fc40.x86_64 kmod-v4l2loopback-6.9.9-1.surface.fc40.x86_64-0.13.1-1.fc40.x86_64 kmod-xone-6.9.9-1.surface.fc40.x86_64-0.0.git.115.fdbb71f1-1.fc40.x86_64 kmod-openrazer-6.9.9-1.surface.fc40.x86_64-100.0.0.git.530.886f986d-1.fc40.x86_64 kmod-xpadneo-6.9.9-1.surface.fc40.x86_64-0.9.6-2.20240423git73be2eb.fc40.x86_64 kmod-evdi-6.9.9-1.surface.fc40.x86_64-1.14.5-1.fc40.x86_64 kmod-kvmfr-6.9.9-1.surface.fc40.x86_64-0.0.git.22.68286efd-1.fc40.x86_64

I'm assuming the libwacom stuff is the key.

[valerie-tar-gz]

Apparently libwacom-surface is a library for libwacom which IS included with Bazzite, and the two shouldn't conflict. Gonna reinstall Bazzite and see if this fixes my issue. If it does, might be possible to include with the base image.

I'm not sure that it could be related, but there is also this issue with ublue images related to tablets: https://github.com/ublue-os/main/issues/622

Surface Pen 2 doesn't work for me until I install iptsd. Maybe that package is being pulled?

Hi, @valerie-tar-gz. I'm Dosu, and I'm helping the bazzite team manage their backlog. I'm marking this issue as stale.

Issue Summary:

• The Surface Pen does not work with Bazzite, unlike with Bluefin.
• Attempts to resolve the issue by layering the opentablet driver were unsuccessful.
• You discovered the pen stops working when rebasing to a non-surface image.
• Identified several surface-related packages, including libwacom-surface, as potentially key.
• @Potajito and @Saroufim suggested related issues and potential solutions, such as installing iptsd.

Next Steps:

• Please let us know if this issue is still relevant to the latest version of the bazzite repository by commenting here.
