I have been running Endeavour (Gnome flavour) for two weeks now, on a desktop PC and on a laptop.
Back in 1999-2000 I started experimenting with RedHat 5.2, dualbooting with Win95.
A short while later I have been running SUSE linux for a few years, followed by staying on Ubuntu until 2020. By that time I had been free of Windows on all of my machines.
In the mean time I had a little experiment with Gentoo, but broke too many installs trying to upgrade. Before arriving at Endeavour I have been running Manjaro as my desktop for two years.
Loving it so-far and getting familiar with the nice articles on the Wiki.
Welcome onboard! I also started my Linux career with Red Hat at my current workplace around the same time as you. Then came Suse, then Debian for a long time, where I learned to use Linux commands. Then Linux Mint followed, and then the Arch line with Manjaro, Antergos, and I’ve been using EndeavorOS with satisfaction for three years now.
