This is from 5.10. Warty 4.10 was the first Linux distro I actually installed, after only using a Knoppix live CD previously. I miss those days. A lot has improved for Linux but it seemed like Ubuntu was onto something. Then in 2010s they lost their way.
I had an 8.04 CD that started me on my journey. I remember the boot sound to this day and miss my GTK 2+Compiz+Emerald setup. You can sort of still get there today, but with little to no modern themes being made, it’s hard to justify.
That was peak Ubuntu for me. I actually do mostly like where Gnome ended up but it just felt so new and fresh at the time. Until 2002, I had only ever used Windows and old Macs. When I saw what FOSS could be and Ubuntu then made it really easy, my mind was blown.
