Common Tasks

Set up a new game via Flatpak

flatpak search "game name"
flatpak install flathub <app-id>
flatpak override --user --device=dri --socket=wayland <app-id>

Fix game performance issues

1. Enable MangoHud: MANGOHUD=1 %command%
2. Check GPU freq: cat /sys/class/drm/card0/device/pp_dpm_sclk
3. Check thermal: cat /sys/class/thermal/thermal_zone*/temp
4. Try Proton Experimental: set in Steam > Compatibility
5. Check VRAM: games with 4GB+ VRAM may struggle on Steam Deck

Stream a game to another device

1. Install Sunshine (Flatpak)
2. Configure in Web UI (localhost:47990)
3. On client: install Moonlight
4. Connect using Tailscale IP or local IP

Troubleshooting

Problem	Fix
Game won't launch	Check Proton version, try different runner
Black screen	Gamescope res, HDR toggle, Wayland vs X11
Stuttering	VRAM, thermal, MangoHud to diagnose
Audio issues	systemctl --user restart wireplumber pipewire
Sunshine no video	Check GPU access, Sunshine permissions
Flatpak crash	flatpak repair, check permissions
Wine missing DLL	protontricks <appid> <dll_name>
Controller not working	Steam Input, evtest, kernel modules
