Installing AMD GPU Drivers on Ubuntu 22.04 for AMD Graphics Cards

This guide walks you through installing AMDGPU drivers and configuring kernel parameters (mem_encrypt=off and amdgpu.sg_display=0) to ensure stable graphics on AMD systems.

---

Step 1: Update system

sudo apt update && sudo apt upgrade -y

---

Step 2: Download and install AMDGPU drivers

1. Visit the official AMD support page: https://www.amd.com/en/support/download/linux-drivers.html
2. Search for your GPU model (e.g., Radeon 780M) and choose Ubuntu 22.04.
3. Download the amdgpu-install .deb package or use the command:

sudo dpkg -i amdgpu-install_6.3.60304-1_all.deb
sudo apt update

4. Install the driver:

• For graphics only:

sudo amdgpu-install --usecase=graphics --accept-eula

• For graphics + ROCm (optional, if using for compute workloads):

sudo amdgpu-install --usecase=graphics,rocm --accept-eula

---

Step 3: Add kernel boot parameters

To fix boot issues (e.g., black screen), add the following parameters to GRUB:

mem_encrypt=off amdgpu.sg_display=0

Edit the GRUB configuration:

sudo nano /etc/default/grub

Find the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Replace with:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_encrypt=off amdgpu.sg_display=0"

Update GRUB:

sudo update-grub

Reboot your system:

sudo reboot

---

Step 4: Confirm it works

After reboot, run:

cat /proc/cmdline

You should see mem_encrypt=off and amdgpu.sg_display=0 in the output.

---

Done!

Your AMD GPU should now be working properly with correct settings for Ubuntu 22.04.
