This a kind of noob question... I've been using Nvivia cards since... forver. But I'm a total noob about AMD. It's the first time I put my hands on one of these.
The situation is I'm tired of struggling with the Nvidia propietary drivers since I've got the GTX960. Switched to nouveau a couple of months ago and performance is not so great. So I've got an RX560 trying to say goodbye to the Nvidia hardware for once and forget about the drivers mess just using what's in the kernel.
The thing is I don't know how the heck to switch the drivers in sid. The card works right out of the box in my Void install, but for some reason I don't manage to get it working for the sidbox. If I blacklist nouveau, poweroff, switch the GPUs and boot, grub doesn't even show up and the boot process stalls with udev saying something like that "the slot" is already in use and it freezes there forever.
Apparently I already have all the needed packages (firmware, xserver-xorg-video-amdgpu, the mesa stuff, etc...) onboard.
Please, someone able to shed some light?
Thanks a bunch in advance.
