How To Set Permanent 2560×1440 Resolution on Ubuntu 18.04 with Nvidia and Multiple Monitors

Ubuntu 8

In this guide, we will walk you through the process of setting a permanent 2560×1440 resolution on Ubuntu 18.04 with Nvidia and multiple monitors. This can be particularly useful if you are using a high-resolution monitor and want to take full advantage of its capabilities.

Quick Answer

To set a permanent 2560×1440 resolution on Ubuntu 18.04 with Nvidia and multiple monitors, you can create a custom configuration file using the nano text editor. Add the necessary lines to the file, save it, and restart your computer for the changes to take effect.

Prerequisites

Before we begin, ensure that you have the following:

  • A system running Ubuntu 18.04
  • Nvidia graphics card installed and drivers updated
  • Access to a terminal and necessary administrative privileges

Step 1: Open Terminal

First, open your terminal. You can do this by searching for the terminal in your Ubuntu dashboard or by using the shortcut Ctrl + Alt + T.

Step 2: Create a New File for Monitor Configuration

In the terminal, run the following command:

sudo nano /etc/X11/xorg.conf.d/10-monitor.conf

This command will open the nano text editor with administrative privileges (sudo) to create or edit the file 10-monitor.conf in the directory /etc/X11/xorg.conf.d/.

Step 3: Add Configuration to the File

In the nano text editor, add the following lines:

Section "Monitor"
 Identifier "Monitor0"
 Modeline "2560x1440R" 241.50 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync
 Option "PreferredMode" "2560x1440R"
EndSection

Here’s what each line does:

  • Section "Monitor": This line begins the configuration section for the monitor.
  • Identifier "Monitor0": This line sets the identifier for the monitor. If you have multiple monitors, you may need to change this.
  • Modeline "2560x1440R" 241.50 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync: This line defines the custom resolution mode. The parameters after the mode name (2560x1440R) specify the timings for the mode.
  • Option "PreferredMode" "2560x1440R": This line sets the preferred mode to the custom resolution mode.
  • EndSection: This line ends the configuration section for the monitor.

After adding these lines, save the file by pressing Ctrl + O and then exit nano by pressing Ctrl + X.

Step 4: Restart Your Computer

After saving the file and exiting the text editor, restart your computer for the changes to take effect. When your computer reboots, the 2560×1440 resolution option should be permanently available in your display settings.

Troubleshooting

If you encounter any issues or the file 10-monitor.conf doesn’t exist, you can try alternative methods such as using the ~/.xprofile or ~/.profile files.

For more information on these alternatives, refer to the Ubuntu Community Help Wiki.
