Omarchy OS Kernel Manager – Safely Switch Between Arch & Cachy Kernels

OKM – Omarchy Kernel Manager, a standalone tool that lets you safely install, switch, test, and remove kernels on Omarchy OS.

This tool is the natural evolution of the kernel-switching feature you once built into your gaming script — now rebuilt as a clean, dedicated application that makes experimenting with different kernels simple and safe.

The video walks through what OKM can do, how it works, and how to remove kernels and return to stock whenever you want.

🔹 Why This Tool Exists

You discovered during earlier gaming comparisons that CachyOS kernels can offer real performance and latency benefits, depending on the game.
A lot of people also try to mash Omarchy together with CachyOS.
Instead of hacking the two together, OKM lets Omarchy users simply swap kernels freely and cleanly.

Your old method worked, but this new version is much more robust, safer, and easier to use.

🔹 What OKM Can Do

The script allows you to:

✔ Install multiple kernels
• Standard Arch kernel
• Arch LTS
• Arch Hardened
• Arch Zen
• CachyOS kernels (bore, base, deckify, zen, etc.)

✔ View your current kernel
• Shows which kernel is running
• Shows protected/base kernels

✔ Switch kernels safely
• Adds each kernel to the boot menu
• Lets you test one at a time for latency or performance benefits

✔ Remove kernels
• “Revert to Stock and Clean Up” option
• Select any or all installed kernels for removal
• After reboot, only the base kernel remains

✔ Fully reversible
• Install → test → remove → reboot
• Zero permanent changes to your system setup

🔹 How OKM Is Installed

The transcript shows:
• You download the script from your link
• Make it executable with chmod +x
• Run it once to install
• Launch it via the keybind Super + Shift + K

You mention that Git drives you crazy, so the script is provided via direct link instead.

🔹 Live Demo (as shown in the video)

The following actions are demonstrated:

• Install Linux Zen kernel
• Kernel downloads
• Added to boot menu
• System rebooted into Zen successfully

• Install CachyOS kernels
• Bore kernel installed
• Deckify kernel installed
• Reboot shows all kernels listed
• Booting into each one works correctly

• Remove kernels
• Using the “Revert to Stock & Clean Up” option
• Select kernels via simple keyboard UI
• After reboot, system returns to stock Arch kernel only

• Update behaviour

When running a system update with a “foreign” kernel installed, Omarchy displays a warning — you show exactly what this looks like.

🔹 What’s Coming Next

You reveal that OKM is Phase 1.

Your next project:
A performance mode inside the WOPR Games Launcher
This will apply CachyOS-style system optimisations BEFORE launching GameScope.

You explain this will need to detect:
• Ryzen P-states
• Intel P-states
• Swappiness
• Other low-level power/performance settings

This will become “Version 5” of your gaming script.

⸻

🔹 Final Thoughts

You love Omarchy for its speed, its workflow, and its keyboard-driven design — and you’re not interested in switching to KDE, GNOME, or XFCE.

OKM is part of making Omarchy as fast and polished as possible while keeping the aesthetics and usability intact.

You remind viewers that these scripts are experimental — excellent for test machines, but not for production systems.
