Arch Linux enables as many compile time options as possible resulting in packages that depends on many libraries. For example, gnome-control-center depends on cheese because there is an option to make a photo and use it as gnome avatar. However, this is what is also what makes me like Arch much more than any other distro. You can always find any feature or documentation included in the same package unlike Debian derivatives.
Drew only brought up rebuild times in relationship to vulnerabilities. However, since the Arch ships as many features as possible the amount of rebuilds would be immense. You may be willing only rebuild in case of CVE but fresh and up to date software is another reason I love Arch. For disto maintainers build times are critical factor. This is why the Haskell on Arch ships as dynamic libraries. (answer from AMA)
Hello there,
To rule out physical damage to the Webcam hardware, can you boot up a Linux LiveCD/USB such as Ubuntu 16.04 and test the webcam with the in-built camera app (They call it Cheese on Gnome desktop, see the wiki https://wiki.gnome.org/Apps/Cheese).
At the moment, there's no reference to the Camera driver on Asus' driver support page for that model, only system utilities such as the keyboard Filter device driver.
