Fn-Taste

So tauschen Sie die Tastaturtasten Fn (Funktion) und Strg (Steuerung) im BIOS

Starte den Computer neu.
Rufen Sie das System- BIOS.
Gehen Sie zu Config -> Tastatur / Maus -> Fn und Ctrl Key Swap.

Verwendung der Funktionstasten ohne Drücken von Fn

Drücken Sie Fn + Esc , um die Fn-Sperre zu aktivieren und die Hotkey-Funktion zu deaktivieren.

Greifen Sie auf das BIOS.
Wählen Sie im BIOS Menü die Registerkarte Konfiguration.
Wählen Sie den Hotkey-Modus und setzen Sie ihn auf Deaktiviert.
Speichern und beenden Sie das BIOS Menü (drücken Sie F10 und dann die Eingabetaste).

Your system has UEFI Secure Boot enabled.
UEFI Secure Boot requires additional configuration to work with third-party drivers.
The system will assist you in configuring UEFI Secure Boot. To permit the use of third-party drivers, a new Machine-Owner Key (MOK) has been generated. This key now needs to be enrolled in your system’s firmware.
To ensure that this change is being made by you as an authorized user, and not by an attacker, you must choose a password now and then confirm the change after reboot using the same password, in both the “Enroll MOK” and “Change
Secure Boot state” menus that will be presented to you when this system reboots.
If you proceed but do not confirm the password upon reboot, Ubuntu will still be able to boot on your system but any hardware that requires third-party drivers to work correctly may not be usable.
