If you are running Ubuntu 22.04 on a system with an AMD GPU and encounter a black screen after resuming from suspend or hibernation, you’re not alone. This list covers ten practical fixes tailored for users facing this frustrating issue, from kernel tweaks to driver adjustments. Whether you’re a Linux enthusiast, developer, or casual user, these solutions will help you restore your display functionality without reinstalling your OS.
1. Update to the Latest Kernel Version
Ubuntu 22.04 initially shipped with Linux kernel 5.15, which had several issues handling AMD GPUs during resume. Upgrading to a newer kernel, such as 5.19 or the latest 6.x series available via Ubuntu’s HWE (Hardware Enablement) stack, can resolve many black screen problems. These kernels include improved AMDGPU driver support and bug fixes related to suspend/resume cycles.
2. Use the AMDGPU Driver Instead of Radeon
Ubuntu supports two main open-source drivers for AMD GPUs: amdgpu and radeon. For modern AMD graphics cards (GCN 1.2 and newer), the amdgpu driver is recommended as it offers better power management and resume stability. Ensuring your system is using amdgpu instead of the legacy radeon driver can prevent black screens after suspend.
3. Disable Wayland and Switch to Xorg
Ubuntu 22.04 defaults to Wayland for some configurations, but AMD GPU support on Wayland is still maturing. Switching your session to Xorg by selecting it at the login screen can improve compatibility and stability, reducing the chance of black screens on resume. This is especially true for setups using proprietary or mixed drivers.
4. Add Kernel Boot Parameters for AMDGPU
Modifying kernel boot parameters can address resume-related issues. Adding parameters like amdgpu.runpm=0 disables runtime power management, which sometimes conflicts with suspend/resume. Alternatively, amdgpu.dc=0 disables the display code, which can help if the black screen is related to display output initialization.
5. Update AMD Firmware Packages
AMD GPUs rely on firmware blobs loaded by the kernel. Ensuring you have the latest linux-firmware package installed is crucial. Ubuntu 22.04 may ship with older firmware versions; updating this package via sudo apt update && sudo apt install linux-firmware can fix bugs affecting resume from suspend.
6. Disable S3 Sleep and Use Deep or Platform Sleep
Some AMD systems have buggy S3 (traditional suspend) implementations that cause black screens on resume. Switching the system’s sleep mode to S0ix (modern platform sleep) or disabling S3 in BIOS/UEFI settings can improve resume behavior. This requires checking your motherboard’s firmware options and possibly updating BIOS/UEFI firmware.
7. Modify GRUB Configuration for Resume Fixes
Editing the GRUB bootloader configuration to add parameters like acpi_osi=Linux or pci=noaer can reduce ACPI and PCI errors during resume. After editing /etc/default/grub, running sudo update-grub and rebooting applies changes. These tweaks help the kernel better manage hardware state transitions.
8. Blacklist Problematic Kernel Modules
In some cases, modules like amdgpu or related DRM components can cause conflicts during resume. Temporarily blacklisting certain modules to test if the black screen disappears can isolate the issue. This is done by creating a file in /etc/modprobe.d/ with the appropriate blacklist directive and updating initramfs.
9. Use a Custom Resume Script to Reset the GPU
Creating a systemd or pm-utils resume script that reloads the AMDGPU module on resume can fix black screen problems by forcing the GPU driver to reinitialize. This involves scripting commands like modprobe -r amdgpu followed by modprobe amdgpu during the resume event, which can restore the display output.
10. Install AMD’s Proprietary Drivers (AMDGPU-PRO)
Though Ubuntu primarily supports open-source AMDGPU drivers, AMD offers proprietary AMDGPU-PRO drivers optimized for professional workloads. Installing these drivers on Ubuntu 22.04 can sometimes resolve black screen issues by providing enhanced firmware and power management support, though they may not suit all users due to compatibility and licensing.
How to Choose
Choosing the right fix depends on your hardware model, usage scenario, and comfort with system-level changes. Start by updating your kernel and firmware packages, as these are the least invasive and often solve the problem. If issues persist, verify your driver in use and try switching between amdgpu and radeon or toggling Wayland vs. Xorg sessions. Kernel boot parameters and GRUB tweaks come next for more advanced users comfortable editing system files. Blacklisting modules or writing resume scripts should be last resorts or targeted tests. Proprietary AMDGPU-PRO drivers are worth considering if you need professional-grade support and the open-source stack fails. Always back up your system before making significant changes.
Frequently Asked Questions
Why does Ubuntu 22.04 show a black screen after suspend with AMD GPUs?
This typically happens due to driver or kernel issues with power management and display output reinitialization on resume. The AMDGPU driver or the kernel may not correctly restore GPU state, causing the display to remain off.
How do I check which GPU driver my system is using?
Run lspci -k | grep -A 3 VGA in a terminal. It shows the kernel driver in use under your GPU’s entry. Look for “amdgpu” or “radeon”.
Is upgrading the kernel safe for Ubuntu 22.04?
Yes, upgrading to the Hardware Enablement (HWE) kernel is officially supported and generally safe. It improves hardware compatibility and fixes bugs but always ensure you have backups before upgrading.
Can proprietary AMDGPU-PRO drivers cause other issues?
They can, especially with some desktop environments or kernel versions. They may introduce incompatibilities or limit open-source features, so test carefully before permanent installation.
Why does disabling Wayland help fix resume black screens?
Wayland’s AMD GPU support is still evolving, and some features like suspend/resume may not work perfectly. Switching to Xorg uses more mature drivers and display protocols, improving stability.
What if none of these fixes work?
Consider filing a bug report with Ubuntu or AMD, checking hardware compatibility, or testing with a different Linux distribution to isolate if it’s a hardware or software issue.
Final Thoughts
Black screen issues on resume with AMD GPUs in Ubuntu 22.04 can be frustrating, but the open-source community and AMD have made significant strides to improve support. By methodically applying these fixes—from kernel updates to driver adjustments—you can restore your system’s functionality without drastic measures. Always start with the simplest updates and progress to more advanced tweaks, keeping your system backed up along the way. With patience and the right approach, your AMD GPU should resume smoothly on Ubuntu 22.04.
