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.
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.
- Accessing the GRUB boot menu: When your system starts, hold down the
Shiftkey to bring up the GRUB boot menu.
- Selecting a different kernel: In the GRUB menu, select the
Advanced options for Ubuntuoption. This will bring up a list of available kernels. Try selecting a different one, such as
- 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/grubfile in a text editor with root privileges, for example, by running
sudo nano /etc/default/grubin a terminal. In this file, find the line that says
GRUB_DEFAULT=0and 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-grubin 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:
- 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.
- 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
- 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
Troubleshooting boot and display issues after an Ubuntu 22.04 upgrade can be a complex process.
