With respins, there are probably at least a few ways to install Slackware with a gui rather than its blue tui. ~ Heck, even a variety of ways to install Slackware itself (~ do they have a gui method too? ~ It’s been a few years since I explored Slackware.)
Slackware has a gui, but it’s not a simple “click here to install” type. It has you creating your own partition table, with all the options.
