Unity games on Steam failing with a black screen but audio playing on Linux Mint often stem from corrupted Proton prefixes, NVIDIA driver mismatches after recent updates, or hybrid graphics not properly utilizing the discrete GPU. Recent system changes around a few weeks ago likely triggered this, especially with proprietary NVIDIA drivers. GOG games working on Heroic points to a Steam/Proton-specific issue.
Generate Proton Logs
Enable logging to diagnose the exact failure. Right-click a game in Steam > Properties > Launch Options, add PROTON_LOG=1 %command%, then launch the game. Logs save to ~/steam-[appid].log (find appid in Properties); check the latest one for errors like DXVK/Vulkan issues or NVIDIA failures.[1][2]
Reset Proton Prefix
Corrupted Wine/Proton prefixes cause black screens in Unity games. For each game: Properties > Installed Files > Browse > up two levels to compatdata > delete the numbered folder (e.g., for Olija appid 1129200, delete 1129200). Relaunch to rebuild.[3]
Force NVIDIA GPU
Linux Mint may default to integrated graphics despite proprietary drivers. Right-click Steam/games in menu > Launch using Discrete Graphics. Or add to game launch options: __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia %command% (OpenGL) or __NV_PRIME_RENDER_OFFLOAD=1 %command% (Vulkan/Proton).[4][5]
Additional Fixes
- Disable Steam Overlay and try Proton-GE via ProtonUp-Qt (install from Flathub).[3]
- Run
steam --resetin terminal, then verify game files.[3] - Update NVIDIA via Driver Manager; reboot and test Proton Experimental.[4] Share Proton logs from affected games (e.g., Olija appid 1129200) for more targeted help. Heroic success suggests bypassing Steam’s prefix resolves it temporarily. [3][1]

Bird Mother has a very nice cover! That also underlines the great theme of the game. I think the game is absolutely fantastic. Completely without space, platforming, or any of the other stuff that seems to be in every other game. A mother bird building a nest for her chicks and feeding them. I often let my 8-year-old daughter play this. Thank you for the pics.
