  • Headless Raspberry Pi + VNC: useful resolution

    Breadboards of Canada …

    I just set up a Raspberry Pi Zero to be a little breadboard computer. Running a headless machine only through SSH gets a bit dull at times, so the inclusion of VNC Connect in Raspbian is handy.

    Only problem was that the default screen size — something like 720×480 — was too small for most dialogue windows. Here’s how to enable a more useful resolution of 1024 × 768.

    All of these are enabled from the raspi-config tool, so open a terminal and start it with:

    sudo raspi-config

    Enable Boot to Desktop

    Select 3 Boot Options → B1 Desktop / CLI → B4 Desktop Autologin:



    Enable VNC on Startup

    Select 5 Interfacing Options → P3 VNC, and answer Yes to Would you like the VNC Server to be enabled?:


    Set Screen Resolution

    Select 7 Advanced Options → A5 Resolution → DMT Mode 16 (1024×768) …:


    Once you’ve enabled all of these, raspi-config will ask if you wish to reboot your Raspberry Pi. Once it has rebooted, you should have a usable remote desktop.

    (All of the above screenshots were taken from a headless Raspberry Pi Zero via VNC.)

    These were taken later on a Raspberry Pi 2 I’m setting up for a maker festival booth:

    decidedly smol: 720×480
    fix it to 1024×768 …
    so much better!

    … you need to set a password — even a trivial one — on the Ubuntu Remote Desktop settings. OS X won’t connect to your remote desktop if you don’t set a password.

    That is all.
