 +On the host computer one might configure the network connection, too. Open the system network setup and for the "raspi network" change:
 +   in IPv4: "method" to "Link Local only"

 +==== VNC ====
 +
 +For a VNC connection install the Real VNC on your host computer, then enable VNC on the Raspberry Pi Zero in the raspi-config
 +   $ sudo raspi-config
 +and log in from the host computer with raspberrypi.local\\

 +----
 +==== Set the Desktop Resolution ====
 +
 +For a HDMI size desktop one can uncomment in:
 +    $ sudo nano /boot/config.txt
 +that line:
 +    hdmi_force_hotplug=1
 +Then force the Raspberry for example into that mode:
 +    hdmi_group=2
 +    hdmi_mode=85
 +Group 2 is for the DMT mode that is intended for computer monitors.\\
 +The hdmi mode defines the resolution, for example:\\
 +hdmi_mode=16   1024x768   60 Hz\\
 +hdmi_mode=23   1280x768   60 Hz\\
 +hdmi_mode=85   720p       60 Hz\\
 +All the possible modes one find on:[[https://elinux.org/RPiconfig]]\\
