ERROR: […/src/amd/vulkan/radv_physical_device.c:1877] Code 0 : Device ‘/dev/dri/renderD128’ is not using the AMDGPU kernel driver
This is the smoking gun, btw.
I see you’ve got it working, so I’ll just add a bit of explanation.
AMD GPUs used to use a driver called radeon
. It was replaced with the current amdgpu
driver. For a while, you had devices that were supported by both drivers and you could choose between the stable radeon
driver that was missing features like Vulkan and HDMI audio or the brand new amdgpu
driver that had the newest features but was unstable and not well tested.
The kernel has a policy of not unnecessarily breaking things with kernel changes so even though amdgpu
has been well tested in the years since, devices from that era still default to the radeon
driver and need to be forced onto the amdgpu
driver.
Blasphemy!
4k monitors are beautiful for normal desktop usage, making text crisp and clean with smooth curves and none of that blockiness that comes from low resolution, and with modern scaling settings you can even have 4K text and 1080p graphics at the same time with the same performance as native 1080p.
