Install gvidm by entering the following commands in the terminal:
sudo apt update sudo apt install gvidm
Description:
quickly and easily change video resolutions in X
Running gvidm will pop up a list of available modes and allows the user to select one if desired. This makes it perfect for running from an application menu or a hotkey, so you don't have to use ram for an applet constantly running. If you are running dual or multi-head displays, it will give you a list of screens so you can select the appropriate one.
