Hello!

I am having problems with a touchpad on my new Thinkpad E14 Gen4 (Intel Core7, Nvidia MX550). Fedora 36, Gnome 42.4, Wayland. Touchpad works differently on boot. Sometimes after upgrades it doesn’t work at all (after disabling and enabling it in BIOS it works again). Sometimes touchpad boots in another mode (like right now) and working as mouse. Fedora also suggested to install Carbon X1 firmware update.
