It was not easy to do on Salix like it was on just about every other Linux distro I’ve ever installed. Underneath the friendly “Linux for Lazy Slackers” is Slackware, after all. Second only to Gentoo or Arch “from scratch” in level of difficulty for an ordinary mortal. Much less a technophobe. But I did it. Somehow.
I got the icon set and themes I wanted that were not in the repositories, and the Brave browser (also not in the repositories and without resolution from Slackbuilds using Sourcery, the very cool Salix tool that builds Slackware packages). I actually found it in another Slackware-compatible third-party repository and unpacked it and installed from the command line. Imagine li’l ol’ me using the command line for anything! Much less making and installing software from outside my distro’s own repositories. And no, not like from just adding some high-risk dumbass PPA for Ubuntu either.
And I think that’s the point in using a Slackware-based Linux distribution. You really can’t help but “learn Linux” just from using it as an ordinary casual user. Yet another good reason to use it.
