Describe the bug Installing solaar via dnf (Fedora) or zypper (Opensuse), won't install the udev rule automatically. In Fedora it's not even found in /usr/shara/solaar. The problem, however, is not that. The problem is that the udev rule installed in OpenSuse, is the one that appears here: https://github.com/pwr-Solaar/Solaar/blob/master/rules.d/42-logitech-unify-permissions.rules

This rule doesn't work. It doesn't change /dev/uinput write permission (restart, plug-unplug, you name it, it doesn't do anything).

Then there is this other rule, here: https://github.com/pwr-Solaar/Solaar/blob/master/rules.d-uinput/42-logitech-unify-permissions.rules

The difference between the two is the (first uncommented line): 

KERNEL=="uinput", SUBSYSTEM=="misc", TAG+="uaccess", OPTIONS+="static_node=uinput"

This is missing from the first, but is present in the second rule. Both rules have the same name, and it's the first rule installed by default (at least in OpenSuse).

Adding that line to the rule makes it work.

Is this an omission, is it done on purpose, a bug? I don't know. But maybe it needs to be looked at. Thank you for all your work. Much appreciated.

To Reproduce Steps to reproduce the behavior:

  1. Install solaar
  2. Move rule to udev/rules.d
  3. Reboot
  4. Solaar rules don't work
  5. Add the missing line to the rule
  6. Reboot
  7. Solaar works

Screenshots If applicable, add screenshots to help explain your problem.

Additional context Add any other context about the problem here.

pfps commented 9 months ago

Distributions, even those using Wayland, generally do not install the Wayland version of Solaar's udev rule. The reason is that this version allows any program run by the user to write to /dev/uinput, which is a security hole. The ability to write to /dev/uinput is only needed to simulate keyboard and mouse input - the rest of Solaar does not need this ability.

spxak1 commented 9 months ago

Thanks. So for Wayland, the second udev rule is the one needed. Can we please add this to the guide somehow? It took me a day trying to fix it. Thank you for your response.

spxak1 commented 9 months ago

Thank you. I only now noticed the "detail" in the link https://raw.githubusercontent.com/pwr-Solaar/Solaar/master/rules.d-uinput/42-logitech-unify-permissions.rules : rules.d-uinput.

I missed the uinput part. Maybe if the name of the rule was different for the two?

Thank you and sorry for wasting your time.
