          Taken from this answer:



          xdpyinfo | grep dimensions


          Or to get just the resolution:



          xdpyinfo | awk '/dimensions/{print $2}'


          OR



          xdpyinfo  | grep -oP 'dimensions:s+KS+'

            It works for a single monitor setup but with two monitors it sums both dimensions, for me my two screens return: 3520x1200 pixels

            Good point. On the other hand, this is still useful if he's searching for a single wallpaper to be spanned over all monitors.

          • @aguslr What would be the point of that? Having two 2000x1000 monitors, what use would be a 4000x2000 wallpaper image?

            @Jos, I get it this command would return 4000x1000, that is, it puts both monitors next to each other. For example, Sylvain has two monitors (1600x900 and 1920x1200) and he gets 3520x1200.

          I would just use xrandr:



          $ xrandr 
          Screen 0: minimum 320 x 200, current 3520 x 1200, maximum 32767 x 32767
          LVDS1 connected 1600x900+1920+0 (normal left inverted right x axis y axis) 310mm x 174mm

          1024x768 75.1 60.0
          800x600 75.0 60.3

          DP3 disconnected (normal left inverted right x axis y axis)
          VIRTUAL1 disconnected (normal left inverted right x axis y axis)


          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

            Typically, people use resolution to mean the dimensions. The DPI is not of as much concern as the dimensions are.

          You can also use:



           xrandr | grep ' connected'


          Example of output on one of my machines:



          LVDS connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm

            For what it's worth, when using multiple connected displays and/or offsets with TwinView then xdpyinfo will give you the resolution of the entire set of displays the way they are configured. If you require the resolution of a single monitor or a monitor connected to one of the display ports you need to use xrandr. However, even in that configuration xrandr can be unreliable and not show the resolution. See this example entry from my X windows config file:



            Option "MetaModes" "DP-1: 1440x900 +0+0, DP-3: 1440x900 +1568+0, DP-5: 1440x900 +3136+0"


            The xrandr output looks like this:



            DVI-D-0 disconnected primary (normal left inverted right x axis y axis)
            HDMI-0 disconnected (normal left inverted right x axis y axis)
            DP-0 disconnected (normal left inverted right x axis y axis)
            DP-1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 410mm x 256mm
            1440x900 59.89*+
            1280x1024 60.02
            1280x960 60.00
            1280x800 59.81
            1280x720 60.00
            1152x864 75.00
            1024x768 70.07 60.00
            800x600 75.00 60.32 56.25
            640x480 75.00 72.81 59.94
            DP-2 disconnected (normal left inverted right x axis y axis)
            DP-3 connected (normal left inverted right x axis y axis)
            1440x900 59.89 + 74.98
            1280x1024 60.02
            1280x960 60.00
            1280x800 59.81
            1280x720 60.00
            1152x864 75.00
            1024x768 70.07 60.00
            800x600 75.00 60.32 56.25
            640x480 75.00 72.81 59.94
            DP-4 disconnected (normal left inverted right x axis y axis)
            DP-5 connected 1440x900+1568+0 (normal left inverted right x axis y axis) 410mm x 256mm
            1440x900 59.89*+
            1280x1024 60.02
            1280x960 60.00
            1280x800 59.81
            1280x720 60.00
            1152x864 75.00
            1024x768 70.07 60.00
            800x600 75.00 60.32 56.25
            640x480 75.00 72.81 59.94


            You can see that DP-3 isn't showing a resolution on the line that a grep for "connected" would show. So the best, most consistent, and reliable command I've found for identifying the resolution of any individual connected display is:



            /usr/bin/xrandr --query|/usr/bin/grep -A 1 connected|grep -v connected


            which produces this:



               1440x900      59.89*+
            --
            1440x900 59.89*+ 74.98
            --
            1440x900 59.89*+


            At that point, it's pretty trivial to pick out the different resolutions or grep for only one port.

                Good point. On the other hand, this is still useful if he's searching for a single wallpaper to be spanned over all monitors.

              • @aguslr What would be the point of that? Having two 2000x1000 monitors, what use would be a 4000x2000 wallpaper image?

                @Jos, I get it this command would return 4000x1000, that is, it puts both monitors next to each other. For example, Sylvain has two monitors (1600x900 and 1920x1200) and he gets 3520x1200.

                It works for a single monitor setup but with two monitors it sums both dimensions, for me my two screens return: 3520x1200 pixels

                Typically, people use resolution to mean the dimensions. The DPI is not of as much concern as the dimensions are.

                      For what it's worth, when using multiple connected displays and/or offsets with TwinView then xdpyinfo will give you the resolution of the entire set of displays the way they are configured. If you require the resolution of a single monitor or a monitor connected to one of the display ports you need to use xrandr. However, even in that configuration xrandr can be unreliable and not show the resolution. See this example entry from my X windows config file:



                      Option "MetaModes" "DP-1: 1440x900 +0+0, DP-3: 1440x900 +1568+0, DP-5: 1440x900 +3136+0"


                      The xrandr output looks like this:



                      DVI-D-0 disconnected primary (normal left inverted right x axis y axis)
                      HDMI-0 disconnected (normal left inverted right x axis y axis)
                      DP-0 disconnected (normal left inverted right x axis y axis)
                      DP-1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 410mm x 256mm
                      1440x900 59.89*+

                      1280x1024 60.02

                      1280x800 59.81
                      1280x720 60.00
                      1152x864 75.00

                      640x480 75.00 72.81 59.94


                      You can see that DP-3 isn't showing a resolution on the line that a grep for "connected" would show. So the best, most consistent, and reliable command I've found for identifying the resolution of any individual connected display is:



                      /usr/bin/xrandr --query|/usr/bin/grep -A 1 connected|grep -v connected


                      which produces this:



                         1440x900      59.89*+
                      --
                      1440x900 59.89*+ 74.98
                      --
                      1440x900 59.89*+


                      At that point, it's pretty trivial to pick out the different resolutions or grep for only one port.

                          You can see that DP-3 isn't showing a resolution on the line that a grep for "connected" would show. So the best, most consistent, and reliable command I've found for identifying the resolution of any individual connected display is:



                          /usr/bin/xrandr --query|/usr/bin/grep -A 1 connected|grep -v connected


                          which produces this:



                             1440x900      59.89*+
                          --
                          1440x900 59.89*+ 74.98
                          --
                          1440x900 59.89*+


                          At that point, it's pretty trivial to pick out the different resolutions or grep for only one port.

                          For what it's worth, when using multiple connected displays and/or offsets with TwinView then xdpyinfo will give you the resolution of the entire set of displays the way they are configured. If you require the resolution of a single monitor or a monitor connected to one of the display ports you need to use xrandr. However, even in that configuration xrandr can be unreliable and not show the resolution. See this example entry from my X windows config file:



                          Option "MetaModes" "DP-1: 1440x900 +0+0, DP-3: 1440x900 +1568+0, DP-5: 1440x900 +3136+0"


                          The xrandr output looks like this:



                          DVI-D-0 disconnected primary (normal left inverted right x axis y axis)
                          HDMI-0 disconnected (normal left inverted right x axis y axis)
                          DP-0 disconnected (normal left inverted right x axis y axis)
                          DP-1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 410mm x 256mm
