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.

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"
