alt Hacker NewsArch was young in those days but I think fairly well known? we were quite vocal, opinionated and interjecting our views everywhere by the time of the Xfree86/Xorg switch. Perhaps it is just my view from being a part of it but I remember encountering the Arch reputation everywhere I went. Or maybe it is just the nostalgia influencing me.
Could be. I don't remember Arch being on my radar at that point though. But it wasn't long after I switched from Gentoo to Arch (and then Debian for a decade due to lack of stability before going back to Arch 7 years ago or so).
A few years before the Xorg thing there was also the 2.4 to 2.6 kernel switchover. I think I maybe was using Slackware at that point, and I remember building my own kernel to try out the new shiny thing. You also had to update some userspace packages if I remember correctly: things like modprobe/insmod at the very least.
