Lightdm-slick-greeter no keyboard input when remoting in via RustDeskt

Greetings all,

About two weeks ago I started running into an issue with machines running Arch Linux with lightdm-slick-greeter where when trying to remote in using Rustdesk to a machine that has not logged in yet, there is no keyboard input available. Mouse works, right click and paste even works.

I have been using my ISO, DeLinuxCo with Rustdesk for the last two years and have never had an issue until now.

The workaround is to switch to lightdm-gtk-greeter and everything works fine.

I just wanted to let someone know that there is an issue and if there is anything I can do to help, please let me know.

lightdm-slick-gretter - 2.2.2
lightdm -1:1.32.0

**Cinnamon** 
System:
  Kernel: 6.17.0-rc4-1-MANJARO arch: x86_64 bits: 64 compiler: gcc v: 15.2.1 clocksource: tsc
  Desktop: Cinnamon v: 6.4.10 tk: GTK v: 3.24.50 wm: Muffin v: 6.4.1 vt: 7 dm: LightDM v: 1.32.0
    Distro: Manjaro base: Arch Linux

Start by reproducing the missing keyboard input over RustDesk on an Arch Linux system using lightdm-slick-greeter 2.2.2 and LightDM 1.32.0, then compare the same setup with lightdm-gtk-greeter. Done means keyboard input works at the pre-login greeter while the slick greeter remains enabled, with the relevant environment and reproduction results documented.
