7 € later (+ 2 € for parking) I plug my brand new HDMI cable into my Raspi and power up. Some seconds later I have the menu to increase my disk space. Done. Reboot. Ready. Uh ... and now? I started the Desktop just to check and it felt a bit like in former times with my C64 when I sat in front of the TV with my C64-Computer-Inside-Keyboard. :-) Ok, enabled sshd. Assigned fix IP in the router. Powered off. Unplugged. Put Raspi next to the router onto the wardrobe. Plugged the networkcable in again. Powered up. Connected with kitty . Now ... what exactly? Mhm, let me think. First bring back my HDMI cable? ;-)
