deckctl — Steam Deck / Bazzite System Manager

Manage Steam Deck hardware and Bazzite OS through OpenClaw. Covers gaming performance, system health, Flatpak management, GPU monitoring, and Gamescope session control.

When to Use

• User asks about Steam Deck system status, performance, or configuration
• Flatpak app installation, updates, or management
• Gamescope session or game mode troubleshooting
• GPU/memory/disk monitoring on Steam Deck hardware
• Proton, Lutris, or containerized gaming setup
• Sunshine/moonlight streaming configuration
• MangoHud, vkBasalt, or OBS VkCapture toggles

Prerequisites

• Steam Deck (LCD/OLED) or Bazzite desktop
• gamescope-session-plus@steam systemd service
• Flatpak, podman, rpm-ostree available

Common Tasks

Install a game from Flathub

flatpak search "game name"
flatpak install flathub <app-id>

Check why a game is slow

1. Check GPU frequency: cat /sys/class/drm/card0/device/pp_dpm_sclk
2. Check thermal throttling: cat /sys/class/thermal/thermal_zone*/temp
3. Check if MangoHud is running: pgrep -a mangohud
4. Check Proton version: ls ~/.steam/root/compatibilitytools.d/
5. Check VRAM usage: cat /sys/class/drm/card*/device/mem_info_vram_used 2>/dev/null

Enable/disable performance overlay

# MangoHud via environment
export MANGOHUD=1  # enable
export MANGOHUD=0  # disable

# Persistent for Steam games
echo "MANGOHUD=1" >> ~/.steam/root/steam.sh.d/mangohud.conf 2>/dev/null

Factory reset a Flatpak

flatpak uninstall --delete-data <app-id>

Troubleshooting

Notes

• Steam Deck uses AMD VanGogh APU (RDNA 2, 8 CUs)
• OLED model has same APU, better screen
• Bazzite is Fedora-based with immutable root (rpm-ostree)
• Flatpak is the primary package manager for GUI apps
• Gamescope provides the gaming compositor layer
• Always check thermal zones before diagnosing performance issues
