getsyx - Linux

Overview

getsyx retrieves the screen size of your X display, either in pixels or dots.

getsyx [-pm] [-g | -s | -d | -D] [<display>]

-p : Output in pixels (default).
-m : Output in dots.
-g : Get the dimensions of the geometric work area (default).
-s : Get the dimensions of the window manager work area.
-d : Get the dimensions of the entire physical display.
-D : Get the dimensions of the built-in display (Linux only).
: An optional X display. If no display is specified, the default X display is used.

Example 1: Get the geometric work area in pixels:

getsyx -pg

Example 2: Get the physical display dimensions in dots:

getsyx -md

Issue: The command does not work.

Solution: Ensure the X server is running and that you have permission to access the X display.

getsyx can be used with other commands to automate tasks. For example:

xrandr --output $(getsyx -pg) --auto

This command would automatically set the display resolution to the current geometric work area.
