Release Highlights
The CachyOS team shipped the April 2026 ISO, swapping Octopi for Shelly as the package manager and adding a fingerprint-based sudo prompt via chwd. The snapshot also enables DNS-over-HTTPS, introduces a vRAM-management toggle built on Valve’s graphics-memory work, and changes the default NVMe I/O scheduler to Kyber. Additional defaults include os-prober for multi-boot detection, Intel-CPU power-saving tweaks, and kernel updates from Linux 7.0 and 7.1, improved system responsiveness.
Background & Context
CachyOS is an Arch-Linux-derived distribution aimed at gamers. In early 2026 it surpassed Arch Linux as the most reported distro on ProtonDB, signaling strong community adoption for Linux gaming. The April release builds on that momentum by delivering usability upgrades and performance-oriented defaults that address common bottlenecks on gaming laptops, desktops, and workstations as well.
Timeline
- Early 2026: CachyOS overtakes Arch Linux as the top-reported distro on ProtonDB.
- April 2026: The team publishes the new ISO featuring Shelly, fingerprint sudo and performance tweaks and privacy enhancements.
Why It Matters for Gaming Linux
The fingerprint-based sudo adds a hardware-level barrier to privilege escalation, appealing to security-conscious gamers who frequently install new titles. Kyber I/O scheduling and the vRAM toggle aim to reduce latency and improve frame rates on systems with limited video memory. DNS-over-HTTPS and the unified Shelly manager simplify network privacy and software installation, lowering the technical entry barrier for new Linux gamers.
Official Statements & Responses
The CachyOS developers said the April snapshot “introduces Shelly as the GUI package manager, enables DNS-over-HTTPS for privacy, and changes the NVMe I/O scheduler to Kyber for responsiveness.” They noted “the improved vRAM management toggle leverages Valve’s work on Linux graphics optimization” and “chwd automatically configures fingerprint readers for sudo prompts, detects Intel CPUs for power saving, and handles laptop edge cases.”
