Unlike the Liva, the Brix GB-BXBT-2807 will boot up in Mint without a monitor. The only hiccup I’ve run into is when I VNC into the Brix, it defaults to 800×600 screen resolution. Unfortunately there isn’t a way to change that in Cinnamon’s Display Preferences because there is no monitor to make the changes to.
But we can make the change outside of the Display preference.
First make a script folder.
sudo mkdir /etc/scripts
Create this script:
sudo nano /etc/scripts/vncres.sh
Copy and paste the following script.
#!/bin/bash RES="1366x768" if (xrandr | grep -q " connected"); then echo "Screen connected." else xrandr --fb $RES fi
Make it executable.
sudo chmod +x /etc/scripts/vncres.sh
xrandr is what’s going to allow us to change the screen resolution. The rest of the script checks to see if a monitor is connected before changing the resolution.
Next go to Preferences > Startup Applications, and add your new script.
