From the manpage: -q, --query When this option is present, or when no configuration changes are requested, xrandr will display the current state of the system. So, the point of it appears to be either to report back the results of configuration changes, or to display the initial state of the system before the change. It depends on how "current state" is determined. Yeah, that's a confusing option. > >>> 2021-01-04 19:22:57 root@dipsy ~ >>> # xrandr -q >>> Can't open display >> The '$' in the post above means it should be run from a user account, >> preferably within the X session. > Xrandr is an X utility.
