Enter Gaming Mode Once installed and after re-logging in if requested: 1. Press SUPER+SHIFT+S. 2. A themed TUI will appear. 1. Previous settings prompt If you have launched gaming mode before, you’ll see: • “Previous settings found. Use previous settings?” • Yes – reuse saved resolution and MangoHud options • No – go through the wizards again 2. Resolution selector You’ll be shown your current display (e.g. 3840×2160 @ 60Hz) and: • Native resolution (best quality) • 1440p upscaled from 1080p (more FPS) • Native 1440p • 1440p → 4K upscaled (balanced) • Native 4K/UHD These correspond to different Gamescope render/output combinations. 3. MangoHud overlay Choose one of: • Off – no overlay • Minimal – FPS only, recommended • Full Stats – detailed CPU/GPU metrics, frametime graph, temps, etc. 4. Launch screen A final “Launching Gaming Mode” screen summarises: • Chosen render resolution • Output resolution • Refresh rate • MangoHud preset The script then: • Exports the correct MANGOHUD_CONFIG (if enabled) • Runs gamemoderun gamescope ... -- steam • Stores the Gamescope PID under ~/.cache/gaming-session/session.pid By default Steam is launched in Big Picture/tenfoot mode. Exit Gaming Mode When you’re done: • Press SUPER+SHIFT+R. This runs leave-gamesmode, which: • Finds and cleanly kills the running Gamescope session created by W.O.P.R. • Restores: • CPU governors • GPU performance / power settings (where possible) • Any idle/lock tweaks created for the session • Removes the session lock files in ~/.cache/gaming-session/. If Gamescope failed to start or exits early, the cleanup routines still run to return your system to its previous state.
