How To Increase Screen Resolution on Lubuntu

Ubuntu 21

In this guide, we will walk you through the steps to increase the screen resolution on Lubuntu, a lightweight variant of the popular Ubuntu operating system. This can be particularly useful if you’re working with high-resolution monitors or if you’re setting up a multi-monitor configuration.

Quick Answer

To increase the screen resolution on Lubuntu, you can start by updating your graphics driver using the Intel Linux Graphics installer. If that doesn’t work, you can manually add the desired resolution using the xrandr and cvt commands. However, if none of these solutions work, it’s possible that your hardware may not be compatible with the desired resolution.

Prerequisites

Before we begin, ensure that you have:

  • Administrative access to your Lubuntu system
  • A basic understanding of the command-line interface

Step 1: Update Your Graphics Driver

The first step in increasing your screen resolution is to ensure that you have the latest graphics driver installed. The default driver may not support higher resolutions, and updating it can often resolve this issue.

To update your graphics driver, you can use the Intel Linux Graphics installer. This can be downloaded from the Intel website. After downloading, run the installer and follow the on-screen instructions to update your graphics driver.

Step 2: Manually Add the Desired Resolution

If updating the graphics driver doesn’t solve the issue, you can manually add the desired resolution using the xrandr and cvt commands.

Generate a Modeline

First, open a terminal and type the following command:

cvt 2048 1536

Replace “2048 1536” with your desired resolution. This command generates a modeline, which is a set of parameters that Xorg uses to drive the monitor at your desired resolution.

Add the New Resolution

Next, use the xrandr command to add the new resolution. Copy the entire modeline output from the previous step, then type the following command:

xrandr --newmode <paste your copied modeline here>

This command creates a new mode with your desired resolution.

Assign the New Resolution to Your Display

Now, use the xrandr --addmode command to add the new resolution to your display. You’ll need to know the name of your display, which you can find by typing xrandr without any parameters.

xrandr --addmode <display name> <mode name>

Finally, use the xrandr --output command to set your display to the new resolution:

xrandr --output <display name> --mode <mode name>

Step 3: Check for System Updates

It’s always a good idea to keep your system up to date. Open a terminal and type the following commands:

sudo apt update
sudo apt upgrade

These commands will check for any available updates and install them if necessary. Reboot your system after the update process is complete.

Conclusion

By following the steps outlined in this guide, you should be able to increase the screen resolution on your Lubuntu system. If none of these solutions work, it’s possible that your hardware may not be compatible with the desired resolution. In that case, you may need to consider using a different display or graphics card that supports the resolution you want.

Remember, always be careful when making changes to your system settings. It’s always a good idea to backup your system before making any major changes.

Can I increase the screen resolution on Lubuntu without updating the graphics driver?

It is recommended to update the graphics driver first as it can often resolve resolution issues. However, if updating the driver doesn’t work, you can manually add the desired resolution using the xrandr and cvt commands.

How can I find the name of my display in Lubuntu?

To find the name of your display, open a terminal and type xrandr without any parameters. It will display a list of connected displays along with their names.

Can I add multiple resolutions to my display in Lubuntu?

Yes, you can add multiple resolutions to your display using the xrandr command. Simply repeat the steps mentioned in Step 2 for each desired resolution.

Do I need administrative access to increase the screen resolution on Lubuntu?

Yes, administrative access is required to update the graphics driver and make changes to the system settings.

Will increasing the screen resolution affect the performance of my Lubuntu system?

Increasing the screen resolution may require more system resources, which can potentially impact performance. However, the impact is usually minimal on modern hardware. If you experience any performance issues, you can try lowering the resolution or upgrading your hardware if possible.
