Simply Zenwalk (Also in widescreen format)
Ironically, I do not use Zenwalk at the time of writing, which has reached version 6.4 during my hiatus. Instead I use Linux Mint and Ubuntu. I have a pretty fast laptop at the moment, with an NVidia GPU, so I wanted something with all the whiz-bang shiny features. That said, Zenwalk is great if you do not want all the extra packages offered in the main Slackware line of distros, but something that’s fast, efficient and responsive — even on old hardware.
