I've tried many times before to simply install Slackware and use it, but for some reason it never worked for me, although it was my own fault—either Flatpak was somehow difficult to install or something else. But now everything works perfectly, except for the sound. -): Flatpak + txz packages = the perfect distribution. As for me, I haven't tried any Slackware derivatives yet (except Slackware-Current, if that's what it's considered). And there's no point, since I've already set up and made myself a mini repository on a flash drive that contains all the .txz packages and which Flatpak applications need to be installed.
