Experience the cutting-edge performance of Arch Linux without the configuration barrier. Featuring dual Wayland environments (KDE Plasma 6 + GNOME), pro-grade gaming tuning, universal hypervisor drivers, and an intuitive native graphical installer.
Caelaris eliminates the manual configuration overhead of Arch Linux while preserving total user control and bleeding-edge software access.
Choose between KDE Plasma 6 and GNOME 4x on the fly. Switch within 2 seconds during live preview, and select your preferred desktop at every SDDM login.
Tuned sysctl parameters with vm.max_map_count=2147483642, Feral GameMode, MangoHud overlay, Steam Proton, and CAKE queue discipline to eliminate multiplayer bufferbloat.
PyQt6 multithreaded installation wizard (`caelaris-installer-gui`) supporting guided Btrfs subvolumes (`@`, `@home`, `@cache`), Ext4, automatic driver provisioning, and USB protection.
First-boot acceleration for VMware Workstation (`open-vm-tools`), VirtualBox (`vboxservice`), and UTM/QEMU (`spice-vdagentd`) with automated dynamic resolution matching.
Single bootloader title displaying strictly Caelaris Linux, booting silently directly into SDDM with zero console clutter or flickering kernel messages.
Temporary live user accounts and sysusers definitions are completely purged during installation. Only your personal setup profile exists on the installed system.
Unified low-latency PipeWire sound server with WirePlumber session management, featuring seamless ALSA, PulseAudio, and professional JACK audio routing.
Pre-installed `yay` AUR helper alongside official Arch Linux Core, Extra, and Multilib repositories, plus Flathub sandbox integration for endless software freedom.
See why Caelaris Linux delivers a cleaner, faster, and more versatile computing experience than conventional distributions.
