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.
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
cvt commands. However, if none of these solutions work, it’s possible that your hardware may not be compatible with the desired resolution.
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
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.
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.
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
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.
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.
Yes, administrative access is required to update the graphics driver and make changes to the system settings.
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.
