COSMIC Desktop 1.4 Arrives: Sound Theme, GPU Frequency Stats, and Fractional Scaling Fixes

by Geth Author

What's New in 1.4

System76 released COSMIC Epoch 1.4.0 on July 22, delivering a focused quality-and-polish update to the Rust-native desktop. No headline-grabbing rewrites — just targeted fixes for the friction points that COSMIC users have been filing tickets about since 1.0.

A Default Sound Theme, Finally

For the first time, COSMIC ships with its own default sound theme, delivered through a new cosmic-sound-theme package. Fresh installs of Pop!_OS with COSMIC now have audio feedback out of the box — login sounds, notification chimes, error tones — without requiring users to hunt down a third-party theme. The package is distributed separately so other COSMIC-capable distributions (NixOS, Arch, Fedora) can adopt it at their own pace.

Fractional Scaling Precision Fix

A persistent pain point on hi-DPI displays has been pointer accuracy at screen edges when fractional scaling (125%, 150%, etc.) is active. 1.4 ships an explicit fix for this: the compositor now correctly maps edge-of-screen pointer positions under fractional scaling. If you've ever tried to snap a window to a corner and missed by a pixel or two, this one's for you.

COSMIC Monitor Gains GPU Frequency and Force-Quit

The system monitor application gets two meaningful additions. First, a force-quit button for stuck processes — no more opening a terminal to kill -9. Second, switchable graph types in the GPU panel: you can now display GPU frequency data alongside existing utilization graphs. This brings COSMIC Monitor's GPU visibility closer to what KDE's KSysGuard and GNOME's Resources already offer.

Portal and Network Stability

xdg-desktop-portal-cosmic is now a system service rather than a session-started daemon. The practical effect: file-picker dialogs and screenshot portals now activate reliably even when applications launch quickly after login. NetworkManager integration in the networking applet also received additional stability fixes that should reduce connection-state desync on resume from suspend.

Where COSMIC Stands in Mid-2026

COSMIC remains the only major Linux desktop environment written primarily in Rust. System76 has maintained a roughly monthly release cadence since the 1.0 debut in 2024, and the cadence shows: each release is small, targeted, and ships without regressions. For users on Pop!_OS, 1.4 arrives via the standard package manager. Community ports for other distributions typically follow within a week or two.

The project still has ground to cover — Wayland protocol coverage has gaps, and some applets feel early — but 1.4 is a sign that System76 is disciplined about shipping steady incremental improvement rather than chasing features.
