I'm troubleshooting some video-output weirdness on my workstation where I get video output right up until it appears to load the video driver, at which point the screen goes black. I'm trying to determine which driver I should try to use. So far I've found the Catalyst driver, AMDGPU, and something called AMDGPU Pro.
My use-case is that I primarily want to use my nano as an OpenCL chip, I don't care at all about gaming performance - however it would be nice if I could work with OpenGL/Vulkan.
Is there one driver I should choose for software development over another? I did notice in the AMD APP SDK documentation that it lists off Catalyst by name, but I've also read that AMDGPU Pro should provide OpenCL/GL/Vulkan as well.
I just got an R9 Nano for opencl work on a linux x64 workstation. I'm having a little trouble getting it to display even at the console. I use Crux linux, and I manually invoke X with startx. As it stands, I can see the normal bios stuff, lilo points to my kernel and starts booting, then maybe 1/3rd of the way through the dmesg kernel output, it looks like it tries to load a driver but it either fails or does some weird thing my tv can't interpret.
The guys at the Crux IRC suggested that I recompile my kernel with AMDGPU support set to modular, and then run make modules_install and make firmware_install - these things all appeared to work and execute correctly, but the original problem remains.
