iptsd does not run on SLS

[gerassimosbarlas]

I have followed the installation instructions and even compiled the kernel after applying the patches, to no avail. This is what I get after booting up: $ service iptsd status × iptsd.service - Intel Precise Touch & Stylus Daemon Loaded: loaded (/lib/systemd/system/iptsd.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Fri 2022-09-30 11:47:26 +04; 35min ago Docs: https://github.com/linux-surface/iptsd Process: 3861 ExecStart=/usr/bin/iptsd (code=exited, status=237/KEYRING) Main PID: 3861 (code=exited, status=237/KEYRING) CPU: 2ms

Modules ithc and ipts are loaded and the /dev/ipts directory exists.

I have tried setting intremap=nosid as a kernel parameter. Still does not work. Any help will be appreciated.

You need to build iptsd from source. The iptsd you are running is the build from the package repository, which does not support ITHC based devices.

Solved: after I installed the linux-surface kernel I installed he iptsd module. It is now working. Thank you all for your efforts.

Hey, sorry to bother. I'm currently using and learning NixOS and came across this problem. I'm struggling to find a solution, can you tell me what you did to solve this? Thank you!
