In retrospect it was probably a good thing to learn on because Slackware was so simple but did so little for you. I remember having to read a long HOWTO from the Linux Documentation Project about how to get XFree86 working. Hand crafting /etc/X11/XF86Config, including experimenting to find modelines that worked for my CRT monitor. Learning how to get Apache setup, which was kind of pointless but fun since I was on dialup.
And setting up auto dial up with a PPP session whenever I used anything that needed to get online. That seemed like magic!
Learned a lot there before trying out RedHat (4.x, before Enterprise was a thing) and Debian 1.3 (Bo) and then staying a Debian user for a long time until mostly moving to Ubuntu for server things.
