I know there are multiple questions like this but there was none that helped me till now.
I have a Dell XPS 15 (the 2021 one)
I had the problem on Ubuntu 21.04 then I thought I'd update to 21.10 to fix everything but the problem is still there.
My touchpad isn't recognizing my touches, presses, moves, scrolls, etc. ... But if I input an external mouse, this mouse is working(but the touchpad obviously not).
But it is showing up in /proc/bus/input/devices which you can see here Although it does not look similar to all the Debugging tutorials I read. e.g. this one from ubuntu in this one it also writes at point 2. that I shall uninstall xserver-xorg-input-synaptics but this isn't even installed, I also am not able to get into the VT (?! never used) by pressing Ctrl + Alt + F2 but I'm able to get to a terminal without DE by pressing Ctrl + Alt + F7
as well as in xinput --list

If you want to know more information on my system to help me I'd be happy to share them.
