Linux

Core2Duo with 2 GPUs running 6 monitors. Works like a charm for the last 5 years, it's my everyday desktop and development station.

Downvote away because Manjaro and Wayland.

Gentoo + OpenRC + TDE (therefore X) on both a first-gen Threadripper desktop with 96GB RAM and a laptop from 2008 with an Athlon64x2 processor and 2GB RAM. Updating gcc on the laptop can take a while, but it still serves well enough. Plus a couple of headless Pis that are also running Gentoo. Not overly unusual, but I may well have the only Threadripper of that gen running that specific distro and DE combination anywhere in the world, since each individual item is kind of low probability.

Not sure how unusual it is but I run openwrt x86 on a fanless Asus mini PC as my main router at home.

Now, not so unusual, I have pretty dull and standard "gaming" type PC running stock Debian, but about 20 years ago as a broke mofo I was running a phpBB forum off a wheezing Pentium MMX laptop with no screen (got ripped off a year prior) on Mandrake Linux. The whole thing was just loosely sitting under my bed. Managed to get a userbase of just under a hundred people before I lost interest. I was using Webmin to manage it from another PC.

I had to connect up an external monitor every time I needed to do something I couldn't do remotely. I learned so much from that laptop. "./configure, make, make install" became muscle memory.

My casual-browsing-only netbook is currently running on a RAID0 setup between the internal eMMC and the microSD card because I think it's funnier that way. Nothing useful's stored on there and it's one nixos-rebuild away from being reinstalled so I don't mind the inevitable breakage.

Just started running Arch + KDE on a Kingston Traveller to experiment with setup. Installed from live usb iso and then ran archinstall to the same device.

Runs nicely on my dell xps laptop and my desktop with 3 monitors connected to an Nvidia 1070Ti.

I have NixOS running on my main desktop with some unusual changes:

• / is mounted as tmpfs, with /etc, /nix and /var being mounted from the actual system partition (this actually isn't too uncommon on NixOS)
• For swap, zswap and dynamically allocated swapfiles using swapspace daemon (this is imo the best swap setup if you don't need hibernation)
• Akonadi (KDE's PIM server) using PostgreSQL instead of MySQL
• ISO8601 date format, for this I have glibc's en_DK locale which does this copied to en_SE because Qt has en_SE as the locale with ISO date
• A couple changes to make the layout more like macOS because I can:
  • Partitions are either mounted or auto-symlinked (if they can't be mounted there, such as for the system partition) under /Volumes
  • I patched udisks to also mount devices under /Volumes
  • User home directories are under /Users and root's home is /var/root
  • Keyboard layout changed as far as I can to be mostly like Mac's so I don't have to rethink layouts as much when switching between this and my MacBook
• Can't technically list this anymore since I've had to tear it down for unrelated reasons but NFS using Kerberos authentication for my NAS
• This is apparently very unusual since a lot of games completely break with it but two monitors with the main monitor on the right

I guess my macbookpro from 2009 with Legacy NVIDIA grafics running Arch with GNOME on Wayland is pretty uncommon, lol (Of course using nouveau derivers)

Not mine, but while I was an intern for a lab I enjoyed using a very normal-looking desktop with a casual 4TB of DDR4 and no SSD or HD, dual Xeon configuration. Rather, it did network boot and pivot root into an in-memory filesystem. It had a UPS and typically ran for months entirely from volatile storage and was used to run experimental photo and video processing. This was about ten years ago.

I'm not too sure how unusual it is, but I have a satellite tracker on a pi 3 b+ based on satnogs. It helps other scientists get data out of cutsats and other satellites. It's pretty easy to set up once you know what to set up.

I once had a butler program on a pi 1 with WiFi chip back around 10+ years ago. No ai, just a bunch of batch scripts + espeak. It was a cool project that would tell us the weather, time, any to-do items, and internet usage ( att had a hard limit of 100gb and I used a script tu tell how much we used per month). Ran for a couple of years and then disassembled it. Still have the GitHub repo. This was many years before Alexa, Google, and the other such projects. It wasn't better at all (espeak sounds so robotic, even when tweaked).

I ran a Bitcoin miner on a pi and made -$4.50ish a month back a decade ago. It was my most popular wiki pages back when I self hosted one. People were really interested, but it never made any money. It was more of a proof of concept . It's pretty easy to compile, but hard to track down all the dependencies. That was waaaay before the asci miners came into play.

Probably the weirdest I've done was play doom on a sansa mp3 player with rockbox installed

Debian testing on a MacBook Air 6,2 (2013). I guess that's kinda weird. Works fine as a netbook: Firefox, Thunderbird, TigerVNC (handles the low resolution well) and SSH. That's all I ask of the thing and it works fine. The only hardware that doesn't work is the webcam, everything else is 100%

It was a free hand-me-down and I put a $45 battery in it so I can use it on the couch. I think what will kill it is when the proprietary charger dies, they cost more used on ebay than the battery did.

I have Void Linux running on a GPD Win 4 (6800u). It performs well enough to emulate Demon's Souls through rpcs3 at 720p 40-60 fps. It has a button on the side which toggles the built in controller between a "kb+m" mode and a normal controller mode, so I wrote a udev rule which opens Steam in big picture mode if its not running already when I switch to the controller mode.

I also sandbox a bunch of applications installed from the repos (including Steam and Firefox) using bubblewrap instead of using something like Flatpak.

I have a custom (half-working) version of slurp which allows starting selection immediately, which in turn allows me to immediately get the position of the cursor, which I use to launch tofi under the cursor (I don't know of any other way to do this on river or even Wayland in general).

I use secureboot with custom keys (using sbctl), and I build a unified kernel image from which I boot with dracut, into a fairly standard LVM-on-LUKS setup, all flicker-free (by manually turning off Plymouth at the right time). UKIs allow me to boot from an efi shell very easily if thing go very wrong.

I run dnsmasq for caching, together with stubby for DoT. I highly recommend at least dnsmasq if you use Steam (fixes weird issues with their downloads).

I toggle running Qt apps' dark/light mode by modifying the qt5/6ct config file with a perl script which darkman runs. I switch the wallpaper in a similar way.

I don't use a status bar, I put most of what should go there into the Emacs tab bar (with custom dynamic icons and everything). It has volume, battery, temperature, wifi, system load, incoming mail, playing music and time display. Everything but temperature display works on both Linux and OpenBSD (and some on Android too).

Honestly there's a bunch more weird stuff but this is getting pretty long.

I have a laptop with an easily accessible m.2 slot, which I use with an m.2 to pcie x16 adapter to connect an external desktop grapics card to game and run ai. apart from that, a diy nas running opensuse and a couple vms for dns, remote nas access, etc

I sometimes use a snap

I use a very very minimal OpenSuse Tumbleweed KDE but I start the DE manually; startplasma-wayland or startx

My work machine isn't too unusual, apart that it has 52 USB devices connected. And here's something you may not know: Linux can't enumerate more than 16 USB ports if the root is configured as USB3, so I had to force all the ports to run in USB2 mode - which is fine in this case, since most of them are serial ports.

Knowing some fringe users, your setup is probably ~3 points or so ahead of the middle of the bell curve. You never know. There's probably a guy running kernel 4.12 on a 1990s CPU with his showa era CRT monitor to play freedoom.

Not THAT unusual, but... I have a Dell R520 server that was leftover/retired from work. I mostly use it for storage due to the amount of disk trays it has. I have all of these disks in a ZFS pool, leaving no actual drives for the OS. However, this was an old VM server, so it has an internal USB 2 port and a ridiculous amount of RAM, so the OS is booted from USB, and I don't use swap.

Boot performance is abysmal (on the rare occasion where I actually need to reboot), but once booted I notice no real downside to having the OS itself on really slow storage. Sure, it's somewhat slow to do os-related stuff such as apt-get, but it's not like I'm in a hurry when doing it. Plus other than updating stuff, the OS storage doesn't see a whole lot of changes/writes.

Now I just need to figure out how to economically attach these 40 additional SAS drives I have. It doesn't have to look good (i.e. fit in the same chassis. Or any chassis at all, for that matter), it just have to work. These additional drives are only 4TB each, but they were free.
