This is an old revision of the document!
Possibly the greatest of all Laptops, it holds a special place in my heart, which is why I have 2, and why two of my children also have one each, and why I have 2 x220 motherboards destined to become either home media streaming machines or home servers (maybe even a proxmox host)
Some hardware details can be found on the x220 Thinkpad page
I have used Linux since somewhere between 2003 and 2004, here is a page that shows my Linux Journey, I am currently running Debian Bullseye with KDE-Plasma
BSD is that 'Other' opensource operating system that is not Linux, My second x220 laptop runs FreeBSD , its a fantastic Operating System and runs the KDE-Plasma desktop well
for more details about BSD (and some thinkpad specific details) just follow this link
KDE-Plasma, I used to run those Minimal Tiling managers, I did it for years, I even created my own LiveCD a few years ago highlighting many of these lighter environments. Then I rediscovered KDE Plasma which is stupidly configurable and surprisingly light
Linux and FreeBSD CLI. Just because I run a full desktop environment does not mean I don't use the command line. In Linux I use Konsole with the Bash shell, In FreeBSD I use Konsole with tcsh. I will be creating pages that explore my favourite CLI apps and how I use them
Many other things to follow, I hope you as a reader will follow this new journey with me
