I was using Gentoo at the time, which meant recompiling the world (in the first case) or everything GUI (in the second case). With a strict order of operations to not brick your system. Back then, before Arch existed (or at least before it was well known), the Gentoo wiki was known to be a really good resource. At some point it languished and the Arch wiki became the goto.

(I haven't used Gentoo in well over a decade at this point, but the Arch wiki is useful regardless of when I'm using Arch at home or when I'm using other distros at work.)
