Vultures rake our claws over COSMIC as Pop OS 24.04 LTS with ‘Epoch 1’ emerges
Summary
System76 has shipped Pop!_OS 24.04 LTS alongside COSMIC “Epoch 1”, the project’s first ground-up desktop environment written in Rust. The Register tested the release on older and modern kit: an ageing ThinkPad W520 where support was patchy, and a Dell XPS 13 which ran the new desktop smoothly. COSMIC is fast, demonstrates strong Wayland behaviour, and offers flexible panels/docks without GNOME extensions, but it still shows 1.0 rough edges.
Installation can be fiddly for dual-boot systems because Pop!_OS uses systemd-boot and places kernels in the EFI System Partition (ESP). Small ESPs (e.g. Dell’s 100 MB default) break installation; GParted’s underlying tooling still struggles with very small FAT32 volumes. Pop!_OS also defaults to a two-tier swap setup (ZRAM then an encrypted swap file/partition) — the reviewer explains simple steps to switch to Zswap and a conventional swap partition for better performance and lower SSD wear.
Key Points
- Pop!_OS 24.04 LTS ships with COSMIC Epoch 1, a Rust-based desktop environment built for Wayland.
- COSMIC is noticeably fast and handles multiple displays, scaling and dynamic desktop changes well.
- Dual-boot installers can fail on systems with tiny EFI partitions; GParted/parted tooling still has limitations.
- Default memory handling uses ZRAM plus an encrypted swap file; the reviewer prefers Zswap with a swap partition and explains how to change it.
- On modern hardware (Dell XPS 13) COSMIC is stable and responsive even under heavier app loads.
- Version 1.0 still has usability rough spots: some settings lag, panel overcrowding, and a few UI inconsistencies.
- COSMIC is already appearing in other distros and is expected in Arch and rolling releases by early 2026.
Author style
Punchy: this is a proper milestone for the Linux desktop. COSMIC shows what a modern Wayland-first environment can do, and System76 has produced a distro+desktop combo that will turn heads. If you care about desktop Linux momentum, read the detail — it matters.
Why should I read this?
Short and honest: if you run Linux on a laptop or fiddle with desktops, this is worth ten minutes. COSMIC is fast, Wayland finally feels useful, and the install/swap quirks are the kind of practical faff you’ll want to know about before you risk your dual-boot setup. We’ve done the poking so you don’t have to.
Context and Relevance
Why it matters: a ground-up Rust desktop shipping as 1.0 is notable — it signals maturity in Wayland tooling and a real challenger to GNOME/KDE for users who want speed and flexible workflows. The installer/ESP problem also highlights an ongoing ecosystem gap: tooling and OEM defaults (tiny ESPs) still frustrate Linux installers. For distro maintainers, desktop developers and power users, COSMIC’s approach to tiling, dynamic desktops and Wayland behaviours is a trend to watch into 2026.
