Garuda Linux Temeraire switches to CachyOS-based kernel, replaces SDDM with Plasma Login Manager

Garuda Linux’s Temeraire release marks a departure from its long-standing linux-zen kernel in favor of a CachyOS-based alternative. This change targets performance or hardware compatibility improvements, though the practical impact will depend on workload and hardware. Existing users upgrading via `garuda-update` will automatically receive the new kernel, but manual intervention may be needed for those relying on custom kernel modules or configurations. The shift also means users must evaluate whether the new kernel’s scheduler or tuning aligns with their use case, particularly for latency-sensitive applications.

The replacement of SDDM with Plasma Login Manager affects both live environments and installed systems. While this unifies the login experience across Plasma editions, it may disrupt custom SDDM themes or scripts. The Hyprland edition’s rewrite in Lua introduces a new configuration paradigm, replacing G-Hyprland presets with Lua-based profiles. Users upgrading will find their settings migrated, but those maintaining custom setups must adapt to the new structure. The switch to hyprlock, Kitty, and awww for core functionality further standardizes the environment but could break existing workflows.

Garuda Toolbox consolidates system administration into a single interface, replacing fragmented tools for kernel management, services, and networking. This simplifies maintenance but may limit flexibility for advanced users accustomed to direct configuration. The installer’s new behavior, selecting the largest supported sector size and aligning LUKS2 encryption, improves compatibility with modern drives but could introduce edge cases for mixed-drive setups. NVIDIA support in Sway is now enabled by default, addressing a long-standing pain point for users of that edition.

The release also includes under-the-hood improvements like Cloudflare R2 mirroring for Arch packages and updates to the Chaotic-AUR infrastructure. These changes aim to improve reliability and transparency but are unlikely to affect day-to-day usage. FireDragon’s updates, including built-in workspaces and notes, reflect a push toward self-contained tooling. While these additions reduce dependency on external solutions, they may not justify switching for users already satisfied with other browsers. The focus on fresh installs suggests existing users will see most changes incrementally.
