A little while ago I wrote about my homelab, and one of the things I mentioned in passing was that I run a Linux desktop container there as a remote development environment.
Then the other shoe dropped – the whole thing coincided with news that the Elementary founders were breaking up. Since I rather like Elementary a lot but am wary of getting caught by niche solutions, I now had added motivation to test vanilla GNOME.
Now that a few weeks have gone by, I thought I’d publish my notes for general consumption.
A small caveat: Fedora ships with GNOME 41 (and at the time I had no clue that GNOME 42 was just coming out), but I don’t think it would make much of a difference – although I may revisit this if anything interesting turns up.
Setting Up The Container
To create the Fedora container, I followed pretty much the same steps as outlined in my notes on NEXTSPACE – just fished out the relevant
LXC container image, got a shell going, and installed it once, making notes so I could start over with a reproducible setup.
So this section is the result of my second go at it, and yielded a usable container that I then mapped my
Sync folder into. That folder, as the name implies, is synced across several containers by SyncThing running on the
LXD host itself1.
If you want to follow up at home, this
dnf invocation should yield a working GNOME environment, plus a few apps I typically use and a few packages I knew I’d need:
sudo dnf install @"Fedora Workstation product core" avahi binutils cabextract docker fira-code-fonts gnome-shell-extension-dash-to-dock gnome-tweaks htop keepassxc net-tools nss-mdns openscad setroubleshoot rsms-inter-fonts tmux vim xorgxrdp xrdp zsh # Lighter alternative # sudo dnf install @GNOME avahi binutils cabextract docker dnf-plugin-config-manager fira-code-fonts firefox gnome-shell-extension-dash-to-dock gnome-software-rpm-ostree gnome-tweaks htop keepassxc keychain net-tools nss-mdns openscad setroubleshoot rsms-inter-fonts tmux vim xorg-x11-font-utils xorgxrdp xrdp zsh sudo timedatectl set-timezone Europe/Lisbon
It’s been a long time since I’ve used vanilla GNOME, and the good news if (like me) you prefer a macOS-like experience, is that you can tweak it fairly easily into something that won’t be jarring (although you’ll have to make some allowances):
Besides the custom theme and window widget locations (set via
gnome-tweaks), eagle-eyed viewers will notice the macOS-like dock (
gnome-shell-extension-dash-to-dock) and the use of Inter and Fira Code fonts.
Although this requires more manual setup than Elementary and is likely to be broken by GNOME 42, most of the required packages ship with the system and I still know my way around it, so… OK, it’s almost admissible as a baseline since I didn’t tweak anything else (for instance, I didn’t bother with themes for
Qt apps and other minor eyesores that are typical in a Linux desktop).
Once window decorations stopped being a distraction, I turned to text.
I spent a long time doing print work during college, so I need to have readable text and don’t like the (serviceable, but very distracting) font substitutions that come with surfing the web on Linux.
sudo rpm -i https://downloads.sourceforge.net/project/mscorefonts2/rpms/msttcore-fonts-installer-2.6-1.noarch.rpm
…and later dropped a set of Segoe UI fonts in, for good measure.
But (and this is the good news, I suppose) I felt zero need to tweak font rendering, as was wont of Linux desktops of ages past.
Everything was excellently rendered regardless of whether I used
RDP (with or without retina resolutions) on my desktop or laptop displays, including a crummy
1366x768 panel. And you get fractional font scaling (via
gnome-tweaks), so a lot of my usual gripes with Linux desktops seem to be gone.
One of the things I like to have is audio via
RDP, if only for desktop alerts and the occasional click-through to a video.
pipewire as its audio system, and even though it ships a shim called
pipewire-pulseaudio, I couldn’t get it to work with the
pulseaudio modules, so I simply removed
pipewire and installed
pulseaudio in my container.
Once most of the above was sorted out, I used the container for nearly two weeks as an anti-procrastination mechanism: I shoved Slack, Twitter, HN and all my doom-scrolling into Firefox.
As expected, this pretty much ensured I’d have a session to it running for hours every day.
I connected to it from my Mac, my Windows machines, my iPad and my Linux desktop, and except when running up against minor graphics performance or audio issues from
RDP I pretty much forgot about where thing were running and just used them, which is great.
More to the point, neither GNOME nor Fedora really got in the way (but keep in mind I’m not a UX zealot–I just appreciate consistency and polish).
I’ve found the baseline GNOME apps to be OK in a pinch, but nothing to write home about. I did try a couple of things I’m likely to use if I ever need to spend a significant amount of time in Linux, and most of my impressions were positive:
- Geary, the e-mail client I’ve been playing with on and off every time I try a Linux desktop, now seems to have less rough edges (but I haven’t really used it, just verified it can now read some of my e-mail).
- The default text editor is very serviceable (I typed a good deal of this draft in it before tidying up in VS Code).
- The built-in
ConnectionsRDP client is… OK in a pinch, but somewhat buggy.
- GNOME Maps, for some unfathomable reason, does not zoom with a mouse wheel on one of my machines, and Night Mode doesn’t work on any of them.
- The “native” app ecosystem seems to be active enough. For instance, I found a cute, simple KeePass-compatible password manager.
So far, GNOME has been… OK… but… sometimes I just ask myself why it’s so obtuse.
For instance, I don’t really get why hitting the
Super) key to invoke the application launcher causes the entire screen to animate and show me active workspaces, windows, and everything else before I even type a single letter to, say, launch a terminal.
After the initial shock it sort of works for me, but I find it completely non-intuitive and a trifle sluggish over
RDP on large displays (especially when I have it blown up to 5K).
To be honest, I’d have preferred a plain and simple Spotlight-like overlay for a launcher, or even (gasp) an application menu by default (there’s an extension that will give you one, but I punted).
But since I don’t rely on a lot of desktop environment functionality and (other than window decorations and icons) I haven’t tweaked anything of substance, the only thing that really annoyed me for the whole two weeks is a relatively minor corner case:
Timezones are Hard
It turns out that if you subscribe to an ICS calendar with timezone info, the Calendar app completely messes up your appointments and alerts – but, ironically, the overview panel you get when you click on the clock seems fine, lulling you into a false sense of security.
This drove me completely nuts since I have a pretty hectic schedule and need to overlay personal, work and project calendars, and it would have been nice to have consistent alerts when I’m immersed in a remote desktop.
Also, my rather peculiar environment posed a few challenges, some of which are Fedora-related and due to their packaging choices.
For instance, to get the GNOME Software Updater to work inside
LXD, I had to trick
fwupd to work inside a container, because for some reason
gnome-software simply refuses to work even when you don’t have
fwupd installed (there is a bug somewhere filed for it).
The fix is pretty simple, though – just let it run even if it’s not doing anything:
sudo vi /usr/lib/systemd/system/fwupd.service # comment this line ConditionVirtualization=!container
Going Bare Metal
Nearly two weeks in, things were working well enough that I felt encouraged to give Fedora another spin, but on actual hardware–in fact, the very same Acer C720 that I installed Elementary on six years ago, and that I mostly use as a thin client these days.
So I flashed it to a USB drive, slotted it in and went through the installer using the defaults (which I really shouldn’t have, as we’ll see when it comes to swap space…).
One of the first issues I tackled was encrypting my home directory–even though most Linux installers can set up full-disk encryption out of the box, I very seldom use it because the user experience is awful (especially if you need to share the machine with someone) and most of my Linux laptops (at least until my Lenovo) were essentially low-resource throwaways where full-disk encryption does make the system appreciably slower.
So I spent a few hours poring over exactly why the tried and true setup I’ve been using with every single Ubuntu and Debian variant failed to work on Fedora–and as it turns out,
SELinux was to blame–or, rather, the Fedora
ecryptfs packages do not do the kind of extra housekeeping Ubuntu ones do.
To set it up properly, I set up a secondary administrative account and resorted to
# this will log suggested policies sudo dnf install setroubleshoot # try to login, then check the logs and see what needs to be applied sudo journalctl -b0
…and after a few iterations, things started working.
Fedora has made the rather amusing decision of using
zram for swap, apparently on the grounds that it’s been working out fine for Fedora embedded and is much faster than actual I/O.
However, it is a spectacularly bad idea to try to use it on a desktop system with 2GB of RAM like this Acer C720, and things would just blow up when I loaded Firefox, VS Code and anything else–often taking out the entire shell.
Some standalone apps just wouldn’t run at all. For instance, I regularly loaded up Bitwig on this machine running Elementary (just for twiddling, not for any serious music editing), and under this setup it would just crash (both
flatpak and re-packaged RPM versions).
Since the default partitioning scheme ate up all my disk with a single
btrfs volume (see, that’s why you should never trust Linux installer defaults…), easy LVM resizing wasn’t on the cards. I ended up adding a standard
sudo btrfs subvolume create /var/swap sudo chattr +C /var/swap sudo fallocate -l 4G /var/swap/swapfile sudo chmod 0600 /var/swap/swapfile sudo mkswap /var/swap/swapfile # brief vi session to add it to /etc/fstab cat /etc/fstab | grep swap /var/swap/swapfile swap swap defaults,sw,nofail 0 0 sudo dnf remove zram-generator-defaults
This “works” in the sense that I can now run more than one app in those 2GB, but I still get some stutters and “stuck keys” while editing code (which I didn’t under Elementary).
My containerized workspace doesn’t need to run SyncThing, but I had to install it on the Acer. Fortunately, there is a nice GNOME shell extension to manage it, with the caveat that the extension doesn’t autostart it itself.
After a few weeks of using Fedora and GNOME this way–reading news and Slack inside Firefox, making notes on xMind and working on various personal projects with VS Code and OpenSCAD, I think it’s likely that I’ll stick to GNOME as my “default” Linux desktop environment from now on, even if I did have to customize it a bit more than I would otherwise do with Elementary.
As an aside, I cannot abide Ubuntu‘s Unity and was never able to get the Elementary/Pantheon desktop running inside an RDP server to my satisfaction, so having GNOME work perfectly via RDP was just icing on the cake.
The only downsides for me are the UX and packaging quirks from both GNOME and Fedora, but as a learning experience, this was OK. A lot of the skills I acquired tussling with Red Hat systems in the deep past came in handy, but fixing some of these things was a good reminder of why I’ve stuck to Ubuntu all these years.
I will likely be rebuilding both my desktop container and going back to Ubuntu 22.04 eventually, but maybe not just yet… If only because it will be safer to wait for 22.04.1, as usual, and I might actually rebuild my
KVM host in the meantime.
