Ubuntu Large Lobster
Towards the end of the halcyon era of the LXFDVD, we started to get concerned. And not just because of the growing threat of global annihilation (which, in hindsight, was much tamer in 2020 than it is now). No, rather by the growing sizes of the Desktop Ubuntu ISO images. In days of yore, we’d never hesitate to include a new Ubuntu release on the DVD, but where not so long ago they were around 2GB (less than half of the space on our optical media), the last LTS release weighed in at a hefty 3.4GB.
It’s not fair to dismiss all this as bloat. As the kernel supports ever more hardware, it grows out of necessity. Additional firmware is required, too. In general, it would be silly to expect individual package sizes to do anything but increase over time. And naturally to pull in more and more dependencies as they evolve. Love ’em or hate ’em, the inclusion of Snaps (Canonical’s preferred package format) have increased Ubuntu’s footprint quite markedly as well. It will come as no surprise, then, that the latest ISO is larger still – around 4.5GiB (or 4.8GB). Making it too bulky for a regular LXFDVD, if that were still at thing.
The selection of GUI applications included in a default install is already pretty minimal. And if you really don’t want LibreOffice and media players (placing you firmly in a minority camp), the Minimal Install option has been available since 18.04. This shaves around half a gigabyte off the standard install size (which we carefully measured to be 11GB in the latest Ubuntu 23.04). New in Lunar Lobster is an official mini ISO, which is only 140MB. This includes not much besides a network installer, which gives you a menu enabling you to select the latest interim or LTS release in either Desktop or Server form. So, it’s a convenience (you don’t have to make lots of different install media) rather than a way of minifying your install. What’s interesting is that it downloads those ISOs into memory and chainloads them, circumventing the time taken to write the full ISOs to USB.
Two years of Wayland
Wayland has been the default display server in the flagship Ubuntu flavour since 21.04. These days, the Gnome/Wayland combination is considered fine (even on Nvidia hardware). Wayland is included in Kubuntu (although it’s not the default) and is not supported by Xfce (and hence Xubuntu) or Xfwm (and hence Lubuntu). Wayland is touted as being lighter and leaner than creaky old X.Org. Any Wayland desktop includes its own X compositor in the form of XWayland, so one might argue that the lighter setup (until XWayland is really no longer required) is to stick with X.Org (or have no GUI at all). New in this release is the use of PipeWire by default. All the flavours have adopted this change and it’s hoped that it’ll solve long-standing problems with PulseAudio and Bluetooth headsets.
