| CacheyOSには互換性のあるカーネルがデフォルトで同梱されるようになり以前のガイドで説明されていた複雑なカスタムISOビルド手順は不要になりました。 標準ISOをダウンロードして通常どおりインストールしてください。 |
| # {Linux sudo dd if=cachyos.iso of=/dev/sdX status=progress conv=sync && sync # Replace /dev/sdX with your USB drive (check with lsblk) # Or use Ventoy, balenaEtcher, Rufus, etc.} |
| # After installation completes uname -r # Should show compatible version (6.18.x LTS recommended, or 6.17.11+) |
| ⚠:インストールISOが起動しない場合 |
|---|
| 標準ISOイメージで問題（ブラックスクリーンなど）が発生した場合はインストーラーが破損したカーネルバージョンに戻ってしまった可能性があります。 下記の「従来のインストール方法」を参照するか、Arch移行方法をお試しください。 |
| wget https://mirror.cachyos.org/cachyos-repo.tar.xz tar xvf cachyos-repo.tar.xz cd cachyos-repo sudo ./cachyos-repo.sh {# Select x86-64-v3 optimization (best compatibility for Zen 2) # Or x86-64-v4 for maximum performance (verify CPU support) |
| # For LTS stability sudo pacman -S linux-cachyos-lts linux-cachyos-lts-headers # Or for latest features (verify version is compatible) sudo pacman -S linux-cachyos linux-cachyos-headers # Update GRUB sudo grub-mkconfig -o /boot/grub/grub.cfg sudo reboot |
| # Install cyan-skillfish-governor-smu (bypasses kernel patches entirely) yay -S cyan-skillfish-governor-smu # Enable and tart sudo systemctl enable --now cyan-skillfish-governor-smu.service # Verify systemctl status cyan-skillfish-governor-smu |
| # Install cyan-skillfish-governor-smu (bypasses kernel patches entirely) yay -S cyan-skillfish-governor-tt {# Enable and tart sudo systemctl enable --now cyan-skillfish-governor-tt.service # Verify systemctl status cyan-skillfish-governor-tt |

| ⚠:標準ISOでインストールが失敗した時 |
|---|
| この方法は標準のCacheyOS ISOイメージが起動しない（画面が真っ暗になるなど）場合にのみ必要です。 ほとんどのユーザーは上記の「標準インストール方法」を使用してください。 |
| sudo pacman -S linux-cachyos-lts linux-cachyos-lts-headers sudo grub-mkconfig -o /boot/grub/grub.cfg |
| sudo pacman -S archiso git git clone https://github.com/CachyOS/CachyOS-Live-ISO cd CachyOS-Live-ISO # Replace standard kernel with LTS grep -rl 'linux-cachyos' ./ ｜ xargs sed -i 's/linux\-cachyos/linux\-cachyos\-lts/g' # Build ISO (follow repo instructions, takes 20-40 min) |
| # Use CachyOS Kernel Manager GUI cachyos-kernel-manager # Download and apply BC-250 GPU frequency patch # Rebuild kernel with patch (8-45 minutes depending on method) |
| # Install CoolerControl yay -S coolercontrol # Enable service sudo systemctl enable --now coolercontrold # Launch GUI to set custom fan curves coolercontrol |
| # 1. Check kernel uname -r # Expected: 6.18.x-lts (recommended) or 6.17.11+ # 2. Check Mesa glxinfo ｜ grep "OpenGL version" # Expected: Mesa 25.1.x+ # 3. Check GPU vulkaninfo ｜ grep deviceName # Expected: AMD Radeon Graphics (RADV GFX1013) # 4. Check governor (use whichever you installed) systemctl status cyan-skillfish-governor-smu # Expected: active (running) # 5. Check GPU frequency cat /sys/class/drm/card1/device/pp_dpm_sclk # Expected: Multiple frequencies # 6. Check sensors sensors # Expected: nct6686-isa-0a20, GPU temp, fan speeds |
