How can I change the screen resolution in Linux?

To change the screen resolution on Linux, you can follow these steps:

1. Open the terminal.
2. Enter the following command to list available monitor and resolution options:

xrandr

1. your decision

xrandr --output your_display --mode your_resolution

In this case, your_display refers to the identifier of the monitor, usually VGA-1, HDMI-1, or DP-1, while your_resolution is the chosen resolution, such as 1920×1080.

1. If the screen cannot display properly in the new resolution, you can try entering the following command to restore to the previous resolution.

xrandr --output your_display --mode your_previous_resolution

“Here, your_previous_resolution is the resolution previously set.”

Please note that these settings may revert to default values after the user logs out or restarts. If you wish to permanently change the resolution, you can edit the Xorg configuration file or use display management tools (such as gnome-control-center, lxrandr, etc.) to make the changes. Different Linux distributions may have different ways to modify the resolution, so please refer to the instructions specific to the distribution you are using.
