Beskrivelse

Indstil Chrome/Chromium til at åbne eller ikke at åbne i maksimeret tilstand, fuld skærm eller kiosk tilstand som standard. Der skal logges ud eller genstartes før det tager effekt.

Forudsætter at “Chrome - Installer” eller “Chromium - Installer” tidligere er blevet kørt.

Parametre

Scriptet tager kun ét parameter. Der vælges mellem none, maximized, fullscreen eller kiosk.

none svarer til standardindstillingen, hvor hverken maksimeret, fuld skærm eller kiosk er aktiveret.

Teknisk note: Disse sættes pt. i .desktop-filerne fremfor via browser-politikker, da det desværre ikke pt. er muligt at styre disse via sidstnævnte fra Googles side.

Dette script er blevet testet og virker på Ubuntu 22.04.
