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?

Hello, @meepytinity

The ExecStart command starts VNC and sets the color depth to 24-bit color with a resolution of 1280x800. You can modify these startup options as well to meet your needs.

In the following line;

ExecStart=/usr/bin/vncserver -depth 24 -geometry 1280x800 :%i

Have you checked that in the /etc/systemd/system/vncserver@.service file.

Let me know how it goes.

Regards,
Alex
