How can I get the monitor resolution using the command line?
Taken from this answer:
xdpyinfo | grep dimensions
Or to get just the resolution:
xdpyinfo | awk '/dimensions/{print $2}'
OR
xdpyinfo | grep -oP 'dimensions:\s+\K\S+'
I would just use xrandr
:
$ xrandr
Screen 0: minimum 320 x 200, current 3520 x 1200, maximum 32767 x 32767

Here I have two screens, the resolution are:
- 1600x900 (laptop)
- 1920x1200 (monitor)
To get only the resolution of your primary monitor, you can also use this python oneliner:
$ python3 -c 'from gi.repository import Gdk; screen=Gdk.Screen.get_default(); \
geo = screen.get_monitor_geometry(screen.get_primary_monitor()); \
print(geo.width, "x", geo.height)'
1920 x 1200
To get the resolution of your extanded desktop (for a multi monitor setup):
$ python3 -c 'from gi.repository import Gdk; screen=Gdk.Screen.get_default(); \
print(screen.get_width(), "x", screen.get_height())'
3520 x 1200
The request was for the resolution. That is given by
xdpyinfo | grep resolution
