Something I’ve been wondering: KDE has this touchpad setting in System Settings:
and presumably most DEs have their equivalent on offer as well. Does anyone know
- what the system’s “underlying” is for this setting (eg a syscall? some /proc/whatever or /opt/whatever or /usr/whatever or /var/whatever or /sys/whatever read/write? a config file to modify? an X11-owned / wayland-owned API?)
- and whether it could feasibly be called/modified temporarily by application code — say a game or a renderer, turning that off on-window-activate and restoring to original setting on-window-deactivate…
Tinkering with simple graphics programming on a simple laptop, I really want the setting unticked while my program runs and ticked back on as soon as returning to the editor and typing code — but before figuring out up some long-winded involved auto-hotkey configuration jumble, I realized it would actually be neat if games/renderers could just (offer to or default to) auto-adjust that, or at least signal to the input system / OS / WM a “preference notification” regarding that.
