Why I use Arch, Wayland/SwayWM and why I don't sometimes

I wrote this post to share my opinions on GNU/Linux distributions, my setup, how I use it, how I got there and what I think is still wrong. I hope somebody may find it interesting or useful.

First of all, a very short distro-hopping history:

  • 2010: Ubuntu
  • 2016: Arch Linux

Very short.

How I started with GNU/Linux

(skip this if you’re interested in my current setup/opinions)

Windows days

I used to use my brother’s old desktop back when I was little. I ran Windows XP, not enough RAM to run Windows Vista though it was already out at the time.

Eventually some family friend gave me a bunch of old desktops the company he worked for had replaced, so I upgraded to Windows 7 as soon as it was released in 2009. I never really used Windows Vista.

I was aware of GNU/Linux: in fact I used to read this magazine on computery stuffs, one of those that came with DVDs with software to try. It was mostly Windows-centric, though sometimes it would talk about Ubuntu and its derivatives.

When it did talk about Ubuntu, it usually also came with an ISO of the Ubuntu derivative in question in the DVD. So I tried Ubuntu 6.06, then some later Kubuntu version, probably 8.04.

I was amazed, I really liked it, especially Ubuntu with GNOME 2. Not really KDE cause it’s bloated AF and it would lag on that thing.

Then… I eventually switched back to Windows. For a stupidly simple reason: Internet connection. We did have 7mbit ADSL, but my room was too far away from the router, in order to connect to the Internet I would have to move the router closer, make ridicolous USB extension cables for the Wi-Fi dongle. I even built a cantenna. Then I’d have to run apt-get update, and hope the link would stay up long enough for it to download the packages.

With Windows it was much easier because I could simply not update it (security 👌💯) and if I needed stuff from the internet, I could just use my brother’s computer or the library’s and use a USB drive to copy it to my computer

Ubuntu

In 2010 though, when I started high school, I got a gift: a laptop. Needless to say it’s much easier to move it close to the router. I initially used it with Windows 7, but after not so long I installed Ubuntu on it, and eventually stopped using Windows completely within a few months.

What made me do the full switch is that I realized that on GNU/Linux I could actually make the computer do whatever I wanted. I started learning shell scripting and Python — self taught.

While I’ve never really done any distro-hopping, I did a lot of desktop hopping.

I started with GNOME 2 on Ubuntu 10.10 Maverick Meerkat. Then Ubuntu switched to Unity. I did like it but it was way too unstable. So I ran away and switched to KDE 4, which was quite stable at the time. When Unity got more stable, I switched to it until I stopped using Ubuntu. I also tried XFCE, i3wm, Enlightenment, LXDE, GNOME Shell, but I every time I eventually switched back to Unity.

I did try Arch Linux, but building packages from the AUR was painful with that cheap laptop, using prebuilt packages from PPAs was much more convenient.

Arch Linux

I switched to Arch in 2016 when I bought my new laptop (ThinkPad X1 Yoga, 1st gen). Building packages with a faster computer doesn’t take too long, so why not? I started with GNOME as it was the environment I was most familiar with, and I kept it until last year.

Why I quit Ubuntu

When I started using Arch, I realized how much Ubuntu was getting in my way. Ubuntu has a lot of tiny patches and customizations which, I must say, are definitely not bad. For example:

  • Apache and Nginx on Ubuntu/Debian have a very nice default config: you just drop in your additions and you’re ready to rock
  • update-alternatives is quite convenient
  • I don’t think snap is bad (I use it on Arch too)

and there are more things I like, I just can’t think of all of them right now.

However:

  • I’m a big boy, I don’t need nano as the default editor, or regular vi replaced with vim. I’m fully capable of typing vi, vim, nvim or nano when I need any of those. Also what’s the thing with vim.tiny and all? Why is there a tiny vim?
  • The venv module is in Python3’s standard library. Can somebody tell me why the hell Ubuntu decided it was a good idea to split it into its own package? Hey thanks for making me save 11KB.
  • They made a whole infrastructure for generating the MOTD. I once had to replace it on a shared computer and I had to reverse-engineer the fucking thing to understand how to remove the freaking Kubernetes ads.
  • Why is it that when I install a package that provides a systemd service it gets enabled automatically? I’m a big boy, I can turn on SSH by myself if I need it.

But most importantly:

WHY IS MAKING A DEBIAN PACKAGE SO HARD? It’s all like hey I heard you like macros, I put macros in your macros so you can script while you script.

It’s a nightmare, there are tons of macros for every existing build system, I’m yet to find a package that actually runs cmake (or whatever is needed) without involving a macro that does the same thing plus who knows what else. There’s something like 20 different build tools that build a package in a slightly different manner. My toilet paper has better instruction than any of those tools, and no page on their wikis can apparently agree on which one is the right one to use (at least last time I checked).

Also good luck finding a MOTU/Debian developer that will maintain your package, they’ll stare at you sitting on top of a pile of paper on which all the macros are printed (therefore very tall), and tell you to read the fucking documentation (well they say “the code is the documentation”, right?). Then each one of them will tell you all the extra requirements you must meet for having them sign your package and upload it into the repos, which hopefully doesn’t involve sucking their dick.

I used to use checkinstall whenever I could but I would find myself running sudo pip/make install way more often than I wanted to.

Also apt/dpkg is slow as hell, for whatever reason 🤷‍♂️

Summary:

  • Unwanted/unneeded “goodies”
  • Gets in your way
  • Overly complicated package management system

Why I use Arch Linux

On Arch, everything is easier. Well not easy as in my grandma could do it, maybe sane is a better way to describe it.

Everyone probably knows the Arch Wiki is the best fucking thing since sliced bread; the Gentoo Wiki is the second best thing.

If you have a little bit of knowledge, you can do whatever you want. If you don’t, the Wiki is there, read every single sentence and the knowledge will permeate your body. Seriously. It’s concise (unless I’m the author of that particular page), not repetitive, clear.

You may say Arch Linux has a reputation of breaking suddenly. Does it break? YES.

How does it break though? Most of the times it’s the user’s fault, and it’s because they have done a partial upgrade. If there’s breaking changes in some library’s API/ABI, you will have to also update all the dependencies (or rebuild the packages that depend on that library, if you built them locally).

However, any experienced user will spot when this happens, and it’s an easy fix. Also, it’s in the Arch Wiki.

Maybe it will be a headache the first few times, then when it happens you’ll know it’s that and you’ll fix it without even thinking about it.

I’ve never ever reinstalled Arch Linux on my laptop. Not even once. I’ve been running and updating the same installation since when I switched to it. I was not very experienced back then. If I could do it you can too.

Once you’re over this, it’s just beautiful. If there’s a bug, you can ask upstream about it, no need to see if the bug was caused by a downstream patch.

You are in charge of deciding what goes into your system, no package is ever pushed down your throat.

Making packages for Arch is often easier than running sudo pip install, sudo make install. The package manager is on your side, not against you.

Summary:

  • Simple, minimalistic in every aspect
  • You are in charge
  • Does’t treat you like a baby
  • Pacman is fast, making packages is easy

Why Wayland

I’ve used X.org on my new computer for a few months, then switched to Wayland (still back when I used GNOME Shell). Yes, there are a few inconveniences, you can’t expect something that’s less than 10 years old replace a well established technology that’s been there from the beginning.

However, using X.org with a HiDPI display is simply a nightmare. It’s just not worth it, especially if you plan to use an external display.

Why Sway (or i3)

Switching to Sway was very painful at first. I made the switch when I had enough of GNOME eating up RAM and crashing for no apparent reason.

I started with a friend’s configs and scripts, printed a keyboard shortcut cheatsheet I could look at whenever I couldn’t remember one, took a few days to customize all the configurations and set up a Git repo to sync them.

It does have many issues: for instance, Xwayland programs are blurred on HiDPI displays to begin with, so I made sure 99% of my programs were running in Wayland-native mode. However:

  • Java programs don’t like Wayland that much (and have issues with the way Sway handles windows even on Xwayland), and I use JetBrains IDEs
  • Up until a few months ago, the only Wayland-native browser I could find was Epiphany (GNOME Web), which is quite crappy. (Now Firefox kinda works, Chromium also sort of does if you build it with some flags enabled)

Other than that, once you get used to it, a tiling window manager is much more convenient than a regular floating one. If you’re used to have tons of terminal tabs open, you can now stop using the tabs and have the window manager do it for you. You can have tabs, or tiles, switch among them, tile them in another orientation, move them between displays fast.

And it works with the mouse too! That’s something that surprised me at first, I don’t know if that’s a thing on i3 but on Sway you can hold your mod key and drag a window around to visually tile it in a different location. Or drag it with the right mouse button to resize it. You can also have floating windows which work pretty much like on other WMs.

I often have five or more terminals open at the same time, and it’s very useful to be able to move them among workspaces, maybe have an eye on htop while on the terminal next to it I’m deploying a service, then move them around as needed or move one to a workspace on its own when more focus is desired.

Summary:

  • Has issues, but they’re manageable (also development is very active)
  • Increased productivity
  • Lightweight

Why not $DISTRIBUTION?

Fedora

Pros:

  • SELinux
  • Making RPM packages is not hard
  • Red Hat is investing a lot on bringing stuff like cast, firmware upgrades to GNU/Linux; big thumbs up for that

Cons:

  • Package manager is slower than fucking APT
  • Narrow selection of third party software
  • Flatpak (I hate it)
  • I can get all the good things on Arch (except for SELinux), without the bad things

CentOS/RHEL

Change my mind

Pros:

  • None, I hate every single time I have to touch a system running one of these two distros.

Cons:

  • Literally no software
  • Not even FUCKING HTOP
  • What about ncdu?
  • Bash? Oh okay at least it does have that.
  • Linux kernel from 5 years ago
  • Systemd from 5 years ago (and Poettering works for Red Hat IIRC)
  • Basically Fedora but you downloaded it from the Wayback Machine
  • It’s used primarily in servers, yet it has a graphical installer. I wouldn’t complain if it actually did work, but it doesn’t. It’s overly complicated, not intuitive and buggy. I’ve seen a coworker try to setup a CentOS VM and it took her 5 days to find out why it would stay stuck in the HTTP proxy selection screen even though her network connection was perfectly fine.
  • No btrfs support (But they have ZFS? Mmh too bad a couple months ago we had a customer who found a corrupted volume in production after a power failure, which is something I would expect a filesystem to be robust against)
  • No literally why the hell are there sooo many people who like it?? You tell me it’s all super tested and stable. Well Ubuntu LTS is just as stable, but the kernel and Firefox are reasonably up to date and htop is available (EPEL and COPR my ass)
  • I mean, I can use it. I just have so many questions. Why? Why!

Manjaro

Cons:

  • You can install it without actually learning how to install Arch.

What I don’t like about Arch Linux

As you may suspect, I am very satisfied with the way Arch Linux works.

However, there is one thing that I hate about Arch, that I think Ubuntu does better:

The kernel is overwritten when you update it 😩

On Ubuntu you have a kernel metapackage, then a package with a different name for every kernel version. When there’s a new kernel in the repos the metapackage is updated to depend on the new kernel.

This way, when you update the kernel, you also get to keep the old one unless you remove it.

This has a few advantages:

  • You can rollback if a kernel update is broken
  • Kernel modules for the running kernel are still there when you update it.

On Arch, there’s a single kernel package that is updated in a rolling fashion. It is updated veeeery often, it’s not too uncommon to get a kernel update every day, sometimes twice a day.

The fact that it overwrites itself means that when you update it you have to reboot, otherwise you won’t be able to load new modules.

Forget that USB drive you plugged in, you gotta reboot now!

In fact, in Arch Linux’s infrastructure servers they themselves work around this by manually upgrading the kernel (source).

On my servers I run pretty much everything in Docker containers, so I don’t really care which distro I’m running, as long as it has htop, WireGuard, btrfs, ncdu. I use Arch on the machines I interact with the most often, Ubuntu on the other ones.
