Add a custom screen resolution in Ubuntu 19.04

xrandr is a command-line tool to interact with the X RandR ((Resize and Rotate) extension, which allows for live (re)configuration of the X server (i.e. without restarting it): It provides automatic discovery of modes (resolutions, refresh rates, etc.) together with the ability to configure outputs dynamically (resize, rotate, move, etc.).

All display outputs may be configured through xrandr. To see the available outputs, just run xrandr via terminal.

subash@SubashDesk:~$ xrandr

If you don’t find the desired resolution in this list, you can create a new one using the following commands.

Get arguments for the new resolution

subash@SubashWork:~$ cvt 1920 1080
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

Create a new mode for this resolution

subash@SubashWork:~$ sudo xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

Add the newly created mode to the display settings

subash@SubashFolio:~$ sudo xrandr --addmode LVDS-1 "1920x1080_60.00"

Your display resolution will probably changed now. If not, go to display settings, choose the new resolution and click on apply.

To make sure Ubuntu boots up with this new resolution, we need to edit the profile using the following commands.

Open .profile

subash@SubashFolio:~$ gedit ~/.profile

Add the following lines to the end of the file

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode LVDS-1 "1920x1080_60.00"
