In the world of computing, compatibility issues between hardware and software are not uncommon. This article will delve into the potential issues you may encounter when running Ubuntu 20.04 on a Ryzen 5000 series CPU, and provide solutions to these problems.
Running Ubuntu 20.04 on Ryzen 5000 CPUs may encounter compatibility issues, but these can generally be resolved. Upgrading to a newer kernel version, adding the "nomodeset" parameter in the grub configuration file, updating AMD firmware, and installing the correct NVIDIA drivers can help resolve these issues. However, specific laptop models may have unique compatibility issues that require additional research and troubleshooting.
Kernel Support and Ryzen 5000
One of the first things to note is that Ubuntu 20.04 comes pre-packaged with kernel version 5.8. However, for optimal compatibility with the Ryzen 5000 series, a kernel version of 5.10 or higher is recommended.
To check your current kernel version, open your terminal and type:
If you’re running a kernel version lower than 5.10, you can upgrade it. Ubuntu provides a handy tool called
ukuu for kernel upgrades. You can install it and upgrade your kernel using the following commands:
sudo add-apt-repository ppa:teejee2008/ppa sudo apt-get update sudo apt-get install ukuu sudo ukuu --install-latest
In these commands,
sudo gives you superuser privileges,
add-apt-repository adds the repository from where you’ll download
apt-get update updates your package lists,
apt-get install installs the ukuu package, and
ukuu --install-latest installs the latest kernel.
Some users have reported issues when booting Ubuntu on laptops with Ryzen 5000 CPUs. A common workaround for this is to add the
nomodeset parameter in the grub configuration file.
To do this, open your terminal and type:
sudo nano /etc/default/grub
Find the line that starts with
GRUB_CMDLINE_LINUX_DEFAULT and add
nomodeset to the list of parameters. Save and exit the file (Ctrl+X, Y, Enter), then update grub with:
nomodeset parameter tells the kernel to not set any mode and use BIOS mode instead, which can help with booting issues.
Brightness control not working properly is another issue reported by users. This can be fixed by upgrading to a newer kernel version and updating the AMD firmware.
You can update your AMD firmware by visiting the official AMD website.
If your system has an NVIDIA graphics card, it’s important to install the correct drivers. First, remove any previously installed drivers:
sudo apt-get remove --purge '^nvidia-.*'
Then add the NVIDIA drivers repository and install the recommended driver:
sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt-get update sudo ubuntu-drivers autoinstall
This will install the best driver for your graphics card. After installation, reboot your system.
