xvfb-run: Pass arguments to the Xvfb server.
$ xvfb-run --server-args "${-screen 0 1024x768x24}" ${command}
try on your machine

The command xvfb-run is used to run a command within a virtual X server environment (Xvfb) to simulate a display. It allows running programs that require a display to work properly, even when there is no physical display available.

The --server-args "${-screen 0 1024x768x24}" option is used to specify the arguments to pass to the virtual X server. In this case, ${-screen 0 1024x768x24} is a variable expansion that sets the screen resolution to 1024x768 with a color depth of 24 bits. The 0 represents the screen number.

${command} represents the command that you want to run within the virtual X server environment. It could be any command or program that requires a display to execute correctly.

Overall, this command launches the specified ${command} within a virtual X server environment with the given screen resolution and color depth.
