By default , resolution of GUI screen is set to 1024x600. If you want to change this resolution you can update the perboot file available in this VM. For that open terminal and run below commands.
cd /var/lib/cloud/scripts/per-boot/
sudo vi ubuntu-browser-per-boot.sh
It will open a perboot script. Press “i” key to get into the edit mode. Update the -geometry 1024x600 flag and set it as per your requirement or you can completely remove this flag from the script. Save the changes by pressing ESC Key + :wq. Make sure to Reboot the VM after making changes in the perboot file. If you completely remove the -geometry flag then it will set the default resolution for your Ubuntu GUI desktop as shown below.
