 ## Megjegyzések
 
 - A container egy `wineuser` felhasználóval fut (nem root)
 - A Wine prefix előre konfigurálva van 64-bit módban
-- A .NET SDK csendben telepítve van
+- A .NET SDK csendben telepítve van virtual display segítségével
 - A projektek a `/home/wineuser/projects` könyvtárban tárolhatók
+- A `run-dotnet.sh` script automatikusan kezeli a virtual display-t
