I’ll start with mine. yes part of this was to brag about my somewhat but not too unusual setup. But I also wanna learn from your setups!
Anyways: I primarily use Gentoo Linux.
I have two headless servers: a Raspberry Pi 4B and a Oracle cloud VM (free tier). Both running OpenRC, and both were running mainline kernel with custom config (I recently switched the Pi to PiFoundation kernel due to some issues). The raspberry pi boots from SSD and has no sd card inserted.
Both servers were running musl libc instead of glibc for a while. This gave me a couple of random issues, but eventually I got tired and switched back to glibc.
I have a desktop running gentoo and a laptop running arch, but hoping to switch the laptop to gentoo soon.
Both are daily driving wayland (the desktop had nvidia card and used for gaming). The desktop is running a kernel with a minimal config that compiles in 2-3 minutes.
What’s your unusual setup like?

I’ve long wanted to attend Ultra Music Festival. It’s somewhat reassuring to hear that I’m not missing out (this year). Sorry that wasn’t better.

Very cool! Thanks for sharing. I’ll pass this on to my friend who’s been at sea with his family for over 1 year.

Gentoo gaming and music production rig working through mostly tty with dwm as a graphical display. I typically stay on tty until I want to play a game, use modern web, or record a song. Otherwise tty with Links browser.
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.
Linux can’t enumerate more than 16 USB ports if the root is configured as USB3
What? Really?
I’m not sure it’s a kernel limitation or a hardware limitation. But it does throw an error in syslog when you connect the 17th device. Not as USB2 though.
This is caused by your root controller’s limited bandwidth and it’s inability to handle that many 3.0 devices at the same time. Some of the newer motherboards with USB C PD have controllers in them that can do a lot more.
It’s basically a hack on part of the company that made the root controller IC. They know they only have enough internal bandwidth to support 16 USB 3.0 devices so they intentionally bork things when you plug in more than that since their Transaction Translator (TT) can’t handle more and they were too lazy to bother implementing the ability to share 2.0 and 3.0 properly.
I’m guessing the decision went something like this…
“We have enough bandwidth for 16 3.0 devices… What do we do if someone plugs in more than that?” “Only a few people will ever have that many! We don’t have the budget to handle every tiny little use case! Just ship it.”
So it’s not Linux fault in this case. Or at least, if it is (a problem with the driver) it’s because of some proprietary bullshit that the driver requires to function properly 🤷
Yeah I figured it might be something like that. But I wasn’t sure it wasn’t a kernel limit - or even a limit in the USB3 specification - because I actually only have one USB3-capable device connected (my cellphone). All the other devices are low-bandwidth USB2 FTDI USB serial converters. I thought it couldn’t be a bandwidth issue when all but one device can only use a fraction of what’s available.
Uh, you’re outputing 52 DMX universes straight from USB? I have questions!
- What software are you using, and is qlcplus really able to do that?
- Have you ever heard the words ArtNet? SACN?
I had no idea what you’re talking about so I had to look it up 🙂
I think you’re making assumptions on what I need many serial ports for and it’s nothing like what you think.
I work for a company that makes measuring instruments that talk serial (RS232, RS422 and UART), we have many variants of our products and I’m tired of plugging and unplugging devices to the same serial ports to test code. Also, I can’t do that remotely when I work from home. So I have many serial ports and all the different devices I need to test my code on regularly are all plugged in and powered at the same time.
No lighting here 🙂
Oh, here I thought you was running a fancy dancefloor or something! TIL the creator of that chip was a prick.
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.
I have 100% done this. I have a picture somewhere of my old ass p3 laptop with an rgb keyboard. So not showa era crt, it’s heisei era LCD (more appropriate considering it’s a Sony vaio f series)

Kept reading it as fridge users and was really flummoxed for a few seconds
Well, you aren’t that far off after all!
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
Damn I need to find out if that works on my machine.
These adapters only exist for pcie 3.0 and m.2 slots for ssds have 4 lanes at best, so you should expect performance to be between thunderbolt 4 and a full x16 slot in a desktop, but it’s been working very reliably for me and is absolutely faster than the iGPU in my laptop. You do typically need a desktop power supply connected to the adapter though, but since it only needs to power the card, it’s fine to go with a lower power one.
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.
Just wondering what’s the power consumption and how long have you had it? I just got my electricity bill after running an R720 for a year and… let’s just say it wasn’t worth the low price after all
Good question. I honestly haven’t got a clue.

I sometimes use a snap
Gross
🤷♀️ the snap works absolutely fine with no issues, the flatpak doesn’t exist and the apt is two years out of date.
I’m not on the outrage boat myself tho
I used Ubuntu for years and never had a single issue with snap. I didn’t even know about the hate back then, nor had I heard of Flatpak. I eventually started to really like it and prefer to get my apps as snaps when available. Eventually I had to give up that laptop because it belonged to my work, and I left for another job. When I installed linux on my personal laptop, I decided to move away from Ubuntu for reasons completely unrelated to snap or proprietary software.
Security.
Check out guix or nixpkgs too, very good alts if flatpak or distro pkg manager doesn’t have it. Snap’s store is proprietary.
Both are terrible for security. Apt is actually safe
Lol, no, it isn’t. Anyone can set up an apt repository and ask you to use it. Many providers do… You might mean the walled garden of an official singular apt repository is safe.
I mean seeing how often malware and other bad stuff has gotten on their. It is bad for the linux eco system in general. Worse then finding random installers on windows

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.
Nice I have a MacBook pro 2016(?) that runs a flavor of Ubuntu over at a local makerspace. It was hard as heck to find and customize the driver’s to get it working, but it does!
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)
Probably the weirdest I’ve dont was play doom on a sansa mp3 player with rockbox installed
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 can only imagine what that much RAM and a system that could hold it cost 10 years ago. Yikes.
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.
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.
