how long ago have you used linux actually? And what distro you used, it had no webcam drivers? CollibriOS? The only time i had to install a driver, it was a graphic tablet one. You know, what did it take to do it?
"yay -S opentabletdriver" to install it
"systemctl --user enable opentabletdriver.service --now" to immediately enable it, and make it run at startup.
It took more to install a proprietary one on windows.
