How can I get Ubuntu 22.04 to properly support my Radeon RX 7900 XTX graphics card?

I recently upgraded my setup with a Radeon RX 7900 XTX graphics card, super excited about the boost in performance, especially for gaming and some graphic-heavy tasks. However, I’ve been tearing my hair out trying to get it to work properly on Ubuntu 22.04. Initially, I thought it would be a breeze to get everything up and running since Linux is known for being pretty accommodating with different hardware, but boy was I wrong!

First off, the screen flickers sometimes, which is super distracting—like I’m stuck in some weird retro game or something. I’ve tried tweaking some settings and digging through infinity online forums, but nothing seems to help. I’ve also noticed that in some graphically intensive applications, the performance isn’t what I expected. I’ll get decent frame rates in some games, but then it drops significantly in others, which is frustrating because I thought this card was supposed to handle anything I throw at it.

I guess I’m wondering if anyone else has run into similar issues or if I’m just missing something basic here. I didn’t want to dive into the world of drivers just yet, but I’ve heard there might be some proprietary drivers that you can install or something. I’ve tried using the ones that came with Ubuntu, but I’m not sure they’re doing much for me.

Also, are there specific settings in the BIOS I should adjust for optimizing the performance of the card? I’ve heard mixed responses on how much that can help. Honestly, I’d appreciate any advice, whether it’s about needing to switch drivers, tweaking configs, or even just tips for getting the most out of my desktop environment while using this card.

I’ve put a lot of effort into making my system perfect for gaming and productivity, so it’s disheartening to hit this wall. If anyone can point me in the right direction or share their personal success stories, I’d be completely grateful! Thanks a ton.

      Radeon RX 7900 XTX Issues on Ubuntu 22.04

      It sounds like you’re going through a lot with your new RX 7900 XTX on Ubuntu 22.04! The flickering and weird performance in games can be super annoying. Here are a few things you might want to try:

      1. Drivers: The first thing you might wanna check is if you have the right drivers installed. Ubuntu often uses open-source drivers by default, which can sometimes be a bit behind on performance. You could try installing the proprietary AMD drivers. Usually, you can do it through the “Additional Drivers” section in Software & Updates. Look for something like “AMDGPU” or similar.

      2. BIOS Settings: As for BIOS settings, make sure that your graphics card is set as the primary device if you have integrated graphics. Some people also mention turning off C-States or enabling Above 4G Decoding, but it really depends on your motherboard. It might help to check your motherboard’s manual or some forums for specific settings that others with the same setup found helpful.

      3. Performance Tuning: Consider using tools like radeon-profile or CoreCtrl for some GPU performance tuning. These tools let you tweak clock speeds and other settings to squeeze out more performance.

      4. Game Settings: For the games themselves, don’t hesitate to lower some settings if they’re too high. Sometimes the most demanding settings put a lot of strain on the GPU. It’s a balancing act for sure.

      5. Community Help: Don’t forget to check out forums like Reddit or the AMD community forums. You might find someone who had the same issues and found a fix!

      This kind of troubleshooting can be a mess, but hang in there! A lot of users have been in the same boat and have managed to get everything working fine. Good luck!



    2. Issues with screen flickering and inconsistent performance on Ubuntu 22.04 with a Radeon RX 7900 XTX can often be attributed to driver conflicts or settings that are not optimized for high-performance tasks. First and foremost, ensure that you have the latest Mesa graphics drivers installed, which provide support for AMD graphics cards on Linux. Use the command sudo apt update && sudo apt upgrade to update your system, and consider adding the Oibaf PPA for the most recent graphics drivers. To do this, execute sudo add-apt-repository ppa:oibaf/graphics-drivers followed by sudo apt update && sudo apt upgrade. This can resolve many flickering issues and improve performance in graphic-heavy applications. Additionally, check your compositor settings as some may interfere with smooth rendering; switching to a simpler compositor like Xfwm or disabling compositing entirely can often alleviate flickering.

      As for performance limitations in gaming, make sure you are using the right graphical settings for your setup. Tools like Steam’s Proton can help optimize gaming performance on Linux. It’s also recommended to set the Performance mode in your graphics settings. Regarding BIOS settings, enable options like Above 4G Decoding and make sure Secure Boot is disabled, as these can help with compatibility and performance. Keep in mind that Linux systems can sometimes require a bit more manual optimization compared to other OS, but relying on community forums for specific tips and benchmarks related to your card can be incredibly useful. Don’t hesitate to reach out to the community for shared experiences—they’re often a treasure trove of practical solutions!
