SDDM uses kwin_wayland. Plasma store the setting for that in $(HOME)/.config/kcminputrc I believe that is used by a different part that is not used by SDDM. Best suggestion is to submit a feature request. Having proper input support would go along with power management as a needed feature for SDDM on wayland.
I should have clarified, as I don't have plasma installed, I don't think sddm can use kwin.
In fact, the docs say it normally uses "weston --kiosk" by default
Either way you'd have to look at the compositor as that is what handles input. I haven't used Weston, so I don't know where to start.
Try this, may be an AI hallucination
mkdir /etc/sddm.conf.d
cat > /etc/sddm.conf.d/custom.conf <<EOF
[Input]
EnableTap=true
EOF
In general avoid overwriting default files, as this .conf.d seems to be pretty standard. Your distro will handle the default .conf but may stop when you changed it manually.
What AI service did you use to get this? It doesn't work, but ChatGPT (3.5) just told me to edit the xorg config to add tap-to-click (which I did but it didn't do anything, probably because X11 is not installed)
Yes GPT 3, it gave me nothing with X11 at least. If SDDM had some abstraction configs for the compositors, that would work.
Did you restart SDDM / the system? And did you try adding that directly to the main file?
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
