How To Fix Ubuntu 22.04 Boot and Display Issues After Upgrade

Ubuntu 9

Ubuntu 22.04, the latest version of the popular Linux distribution, offers many improvements and features. However, like any operating system upgrade, it may also introduce new issues. In this article, we will guide you through the process of troubleshooting and resolving boot and display issues that you may encounter after upgrading to Ubuntu 22.04.

Quick Answer

To fix Ubuntu 22.04 boot and display issues after an upgrade, you can try booting with a different kernel, uninstalling problematic kernels, enabling Bluetooth, uninstalling incorrect NVIDIA graphics drivers, and installing the correct NVIDIA graphics driver. If these steps don’t resolve the issues, seek assistance from the Ubuntu community.

Understanding the Problem

After upgrading to Ubuntu 22.04, you may experience issues with booting your system or with your display settings. These issues can range from the system not booting at all, to the display resolution being incorrect or the network connectivity being unstable.

Booting with a Different Kernel

One of the first things you can try to resolve these issues is booting your system with a different kernel.

  1. Accessing the GRUB boot menu: When your system starts, hold down the Shift key to bring up the GRUB boot menu.
  2. Selecting a different kernel: In the GRUB menu, select the Advanced options for Ubuntu option. This will bring up a list of available kernels. Try selecting a different one, such as linux-image-5.15.0-56-generic.
  3. Making the kernel default: If your system boots successfully with the different kernel, you can make it the default one. To do this, open the /etc/default/grub file in a text editor with root privileges, for example, by running sudo nano /etc/default/grub in a terminal. In this file, find the line that says GRUB_DEFAULT=0 and change it to GRUB_DEFAULT="Advanced options for Ubuntu>Ubuntu, with Linux 5.15.0-56-generic". Save the file and exit the text editor. Then, update GRUB with the new settings by running sudo update-grub in a terminal. Finally, reboot your system.

Uninstalling Problematic Kernels

If the issue persists, it might be due to problematic kernels that were automatically installed during the upgrade. You can uninstall these kernels using the apt remove command.

For example, to remove the linux-image-5.15.0-1025-oracle kernel, you would run sudo apt remove linux-image-5.15.0-1025-oracle. Do the same for any other problematic kernels.

Troubleshooting Additional Issues

If you are facing other issues, such as onboard Bluetooth and audio not working or incorrect NVIDIA graphics driver loading, you can follow the solutions below:

  1. Enabling Bluetooth: If your Bluetooth is not working, you can enable it by running sudo systemctl enable bluetooth. This command enables the Bluetooth service to start at boot.
  2. Uninstalling incorrect NVIDIA graphics driver: If the wrong NVIDIA graphics driver is loaded, you can uninstall it by running sudo apt-get purge ^nvidia-. This command removes all packages that start with nvidia-.
  3. Installing the correct NVIDIA graphics driver: After uninstalling the incorrect driver, you can install the correct one by running sudo apt install linux-modules-nvidia-470-5.15.0-56-generic. This command installs the NVIDIA 470 driver for the 5.15.0-56-generic kernel.

Conclusion

Troubleshooting boot and display issues after an Ubuntu 22.04 upgrade can be a complex process. However, by following the steps outlined in this article, you should be able to resolve most of these issues. Remember to always be careful when modifying system files or uninstalling packages, as incorrect changes can cause further issues. If you need more help, consider seeking assistance from the Ubuntu community.
