Unable to change resolution on Ubuntu 18.04
So i followed this guide https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-debian-10
But when i try to change my resolution through the display settings,it says unable to query the version of the randr extension being used and no randr extension is found.Do anyone have any idea of how i can change the resolution?
