How To Fix Second Monitor Issues on Ubuntu 22.04 with NVIDIA 3080 Ti

Ubuntu 14

When setting up a dual monitor system on Ubuntu 22.04 with an NVIDIA 3080 Ti, you might encounter some issues. This guide aims to provide comprehensive solutions to fix these problems and help you get your dual monitor setup running smoothly.

1. Checking the Driver Being Used

The first step in troubleshooting your second monitor issue is to check the driver being used. You can do this by opening a terminal and running the following command:

sudo ubuntu-drivers autoinstall

This command will automatically install the recommended driver for your system. The sudo command is used to run the following command with root privileges, ubuntu-drivers is a tool to detect and install additional Ubuntu driver packages, and autoinstall is an option that installs drivers that are appropriate for automatic installation including their dependencies.

After running the command, reboot your system to see if the issue is resolved.

2. Switching DisplayPort Cables and Ports

If the first solution doesn’t work, try switching the DisplayPort cables and the ports they are plugged into on the graphics card. This can help you identify if the issue is with a specific cable or port.

3. Adjusting the Refresh Rate

Sometimes, the issue might be with the refresh rate of the second monitor. To adjust the refresh rate, go to the display settings of your Ubuntu system. Here, you can change the refresh rate of the second monitor. Some users have reported that changing the refresh rate resolved their issue.

4. Testing Different Video Card Configurations

If you have multiple video cards or connectors, try different configurations. For instance, disconnect the primary monitor and see if the second monitor works. You can also try plugging both monitors into the same physical card or switching the displays between different cards.

5. Trying Different Driver Options

If the NVIDIA drivers are causing issues, you might want to switch to the Xorg drivers. However, note that this might limit the refresh rate and result in choppy performance.

To switch to Xorg drivers, open the terminal and type the following command:

sudo apt-get install xserver-xorg-video-nouveau

This command will install the Xorg drivers on your system. sudo runs the command with root privileges, apt-get install is used to install packages, and xserver-xorg-video-nouveau is the package for the Xorg drivers.

After running the command, reboot your system to see if the issue is resolved.

Conclusion

While these solutions might not work for everyone due to varying hardware configurations, they provide a good starting point for troubleshooting second monitor issues on Ubuntu 22.04 with an NVIDIA 3080 Ti. If you’re still experiencing issues, it’s recommended to consult official documentation or seek assistance from the Ubuntu community.

Remember, the key to successful troubleshooting is patience and systematic testing. Good luck!
