Linux Vulkan CL650 XP11

[IronCondor]

Hello. Not sure if this is the best part of the forum to post this.  I am loving the Cl650. I finally managed to install Ubuntu 20.04LTS version. Rookie Linux user here. All is well with a learning curve of course. In OpenGL I get high settings in XP with amazing frame rates up to my monitors refresh rate of 144Hz even with airports and ortho. When I switch to Vulkan the displays in the CL650 do not show. They only are working when I pop out the PFD MFD and EICAS.

I purposely left Ubuntu 20.05LTS fully updated upon installation and made no other tweaks. I did no GPU software updates. When I have done this in the past it has broken XP11. Current machine has a AMD 6900XT RDNA 2 GPU.

Curious to know if anyone has made this work under Ubuntu or Linux Mint for XP11 running Vulkan. Any thoughts would be greatly appreciated.

 

Thank you

For what it's worth, I'm running it on Ubuntu 20.04 using Vulkan and have no issues. My specs are: AMD Ryzen 7 3800X, GTX 2080 Super, 32GB RAM.

Please correct me if I'm wrong but at least a few years back the saying was that you would need an Nvidia GeForce card with the proprietary drivers to have full support on Linux, AMD/ATI Radeon is not fully supported on Linux (and shows weird bugs on Windows as well). Personally, I always bought GeForce cards due to those known issues, so I can't tell if the situation maybe improved (but I don't remember having read any comments about improvements over the past years).

I've recently read about other X-Plane addons having issues with 3D rendering on "AMD" as well, even on Windows (not sure if those reports referred to CPU-integrated graphics or dedicated GPUs), so maybe the issues are not even limited to Linux drivers.
