I quickly found out about #distrosiactuallyuse so i'm gonna jump in too!
1. #limuxmint on my HP laptop as daily driver PC
2. #lubuntu 18.04 on an old Acer Aspire One #netbook as a secondary PC
3. #postmarketos on a Huawei P9 Lite, i'm making a port and so far i also got WiFi working!
Jumping on the #distrosIActuallyUse train started by @MNandor here.
1. #fedora - daily driver on @frameworkcomputer and Dell backup laptop
2. #nobara - fedora spin by Eggy that I run on the desktop and a handheld PC
3. #postmarketos - awesome alpine distro running on my PinePhone and soon my Memo Pad 7
4. #chimeraos - distro giving a #steamos like interface for my living room build
5. #popos - a user-friendly distro I used to be support for, what I install for friends and family
Instead of "top X favorite distros", how about a list of distros that are actually useful to you?
1. #archlinux - daily driver
2. #lineageos (let me shoehorn this in, Android has a Linux kernel) - daily driver phone. With #termux.
3. #postmarketos - I found a surprising usecase for it not as a phone, but as a low-power home server.
4. #linuxmint - what I install for friends.
5. #fedora - previous home server
