![]() $ sudo vim /etc/profile.d/external_monitor_resol.sh To add the resolution permanently, create a script called external_monitor_resolution.sh in the directory /etc/profile.d/. The above changes are only temporary and work for the current session (they last until you log out or restart the system). Now open the Displays and check if the new resolution has been added. Next, copy the Modeline (“ 1680x1000_60.00″ 139.25 1680 1784 1960 2240 1000 1003 1013 1038 -hsync +vsync) from the output of the cvt command and use it to create a new mode using the xrandr as shown. You can do this using the cvt utility as follows.įor example, if you need a horizontal and vertical resolution of 1680 x 1000, run the following command. To add a missing or custom display resolution, you need to calculate the VESA Coordinated Video Timing ( CVT) modes for it.

To make xrandr changes persistently, use the nf configuration files for Xorg X server (run man nf for details on how to create a nf file) – this is the most effective method. ![]() Keep in mind that any changes made using xrandr will only last until you log out or restart the system. You can also use the -left-of, -right-of, -above, -below, and -same-as options to arrange your screens either relatively to each other.įor example, I want my external monitor ( DP-1) to be positioned left of the Laptop screen ( eDP-1) in correspondence to the actual physical positioning: $ xrandr -output DP-1 -left-of eDP-1 You can also set the refresh rate using the -rate flag as shown. To set the resolution for a screen for an external monitor named DP-1 to 1680×1050, use the -mode flag as shown.
