I though I was doing a good deed buying a netbook with AMD CPU, because of their FOSS love and such, then they decided that Brazos APUs aren't worth supporting beyond basic features.

Since then I just decided that no matter what, GNU/Linux is not the platform for anyone that actually cares about desktop graphics programming.

Brazos is 2011-era, right? amdgpu has become a thing since then - AMD now officially supports their GPUs on Linux, including those in most APUs.

Except that it doesn't provide the same OpenGL features and hardware video decoding as fxglr.

So much for "supports".

I recently built a new PC and my GPU was a Radeon RX 5700 for exactly this reason.

Way ahead of you here.

And regardless of how https://github.com/RadeonOpenCompute/ROCm pans out, at least you're not sinking skills into a proprietary jail.
