How can I determine X resolution from CLI without randr?

Question

Does anyone know of a way to determine the current X resolution from the command line, without using randr?

Solution 1

you can grep output of xdpyinfo or xwininfo -root or xprop -root.

Solution 2

I'm not sure if xdpyinfo uses RANDR:

xdpyinfo | grep dimensions:

This one assumes the root window's size is the resolution:

xwininfo -root |egrep 'Width:|Height:'

Perfect, thanks! I wound up using "xdpyinfo | grep dimensions"
