Linux

Probably like half a year on Mint. Don't know for certain.
I'm currently on Tumbleweed which is pretty good, though I do have some minor issues which make me want to just switch to Debian. I do work on this machine, so even minor issues are pretty damn annoying for me.

I've only really used Gentoo, Debian and Ubuntu (in that order!), each for years at a time over the past two decades. I suppose it shows how progessively fewer fucks I give about the inner workings of the system.

I also tried to install a copy of... TurboLinux 6, I think? that I got from a Ham Radio swap meet as a kid sometime in the '90s, but I never got it to work.

Archlinux. Many years ago, not sure exactly when, but more than 10years. Last distro I really used before Arch was ZenWalk, slackware based. Arch was the only one that after many tries and over the years remains the most consistent, simple and reliable that I can manage without much effort.

After using on my personal computers Arch I still tried and used on the work machines Ubuntu lts releases. It gave so much problems that I just now use Arch everywhere and anytime I get a new work machine it's what gets installed too.

I have to say that I was a serious heavy distro hoper back in the days and tried basically everything that existed. Just not gentoo. But fedoras, mandrakes, mandrivas, knopix, slackware, bsd, suse, etc, I regularly spent time with them all and was changing a lot and tried many new releases. The longest I've been with a distro was ZenWalk, more than a year or 2 and then Arch appeared on my radar and once I jumped ship, never got the need for anything else.

Edit: Checked some math I think I use arch more than 15years now.

I've been using Linux Mint (Cinnamon) as my only operating system since 2016. No dual booting.

I used Manjaro for 3 years 2018-2021 on my laptop. I think that's the longest yet. Been using EndeavourOS since, almost 2 years now.

Been on Artix Linux for about 3 years. Occasionally there’s a package that breaks, but nothing serious. Been very happy with a minimal environment using Bspwm/sxhkd and the st terminal mainly.

Lets see. Debian since 1997... so 26 years. Back then you had to order 12 CDs through the post.

I don't do distro hopping, because I don't believe there is any significant difference between the capabilities provided by individual distro. So, I switched only when changed jobs (2000-2006 Debian, 2006-2018 various RedHat/Fedora distros, 2018- various SUSE distros (Tumbleweed, now Greybeard).

I was on the same distro for ~10 years, roughly 2010-2020, before I got pulled into the "Apple ecosystem". (Still use Linux on all my servers, though!)

I use(d) Arch, btw 😛

I originally started with Knoppix in 1998 used that unitl i9 switched to ubuntu warty warthog and following versions until unity came out in then I switched to mint as unity constantly crashed my machine. stayed with mint for like 5 years, then moved to fedora for a year, switched to tumbleweed because I got tired of the SELinux in fedora causing issues.

Been on endeavourOS for a year now, and if i do decide to migrate a gain I will be going full vanilla arch.
