What is the method for changing the resolution in Linux?

In Linux systems, you can change the resolution using the following method:

1. You can use the command line tool xrandr to view the current resolution of your monitor and all available resolution options. Then, use the xrandr command to modify the resolution, for example:

xrandr --output <display_name> --mode <resolution>

is the name of the monitor, which can be viewed using the xrandr command; is the desired resolution to set, such as 1920×1080.

1. In the graphical interface, you can modify the display resolution. Most Linux distributions provide a graphical interface in the desktop environment to adjust the display resolution. Usually, you can find the resolution option in display settings or screen settings, where you can select the desired resolution from a dropdown menu.
2. To modify configuration files: Some distributions may require manual editing of configuration files to set the display resolution. Typically, the configuration files can be found in either /etc/X11/xorg.conf or /etc/X11/xorg.conf.d/ directories, where you can adjust the parameters to set the resolution.
