Pen not working on surface pro 7
Hello, I have recently installed Linux (Fedora 36) on my Surface Pro 7 (model 1866) but unfortunately I can't get multitouch and pen working.
I already opened an issue on the linux-surface/linux-surface repo but I was advised to also open one here. Basically I compiled from source both iptsd (from this repo) and linux-surface/intel-precise-touch from their respective master branches as of today (august 25) and the pen seems to work for after a reboot the first time I try it. As soon as I stop hovering and the pen leaves the screen it never works again (evtest also does not detect anything)
I leave here my dmesg and some stuff that might help debugging. Also I do have a fairly bad screen protector but it never gave issues on Windows.
I don't know if I did something wrong but it was not much I did after all, maybe someone else with surface pro 7 can test it out as well?

as guess it is not aboue screen protector any more >80%.
fairly bad screen protector
why you think it is bad?
Hi, I have the same problem, always on SP 7 and Fedora 36. Everything works except pen, and multitouch. I also tested IPTS Touch and IPTS Stylus with evtest, but the latter doesn't return any values.

does you use the compiled version from github repo of linux-surface/iptsd (not one from system repo)
and If I not remember wrong, you haave to do the same for ipts driver in linux-surface/intel-precise-touch
just like author have done (he/she said in 1st comment)

Yes, I have installed iptsd from linux-surface/iptsd/actions.

Regarding intel-precise-touch, I haven’t done that yet, because I'm not sure what to do with the patches. Thank you for help.

You absolutely need that. Skip the patch part if you already use the surface kernel, it just add pen IDs to recognize the hardware they are already included.

Ok now it is much clearer, but I have already installed surface kernel.
[mattiamelodia@surface-pro-7 ~]$ uname -r 5.19.4-1.surface.fc36.x86_64
That should be my version.
Probably something wrong, but if the kernel and iptsd are installed, and touchscreen works, what could be the problem ? How can I use patches to fix the problem ? Thank you for help.
