People who posted here earlier have pointed out how to deal with the hardware - so I won't rehash THAT.I have installed FreeBSD on a spare disk. Everything worked fine until I tried to get X.org running with my AMD 6600 RX. I eventually gave up when I couldn't get pass the black screen when loading the amdgpu module.
I rebooted the computer and tried booting my regular OS. At first I couldn't even get pass Grub. The image just turned black. I forced reboot the computer by holding the power button for a few seconds. I eventually got the OS to boot, only to be greeted with a black screen before it was done loading.
I then tried to boot my second OS, which booted fine after a few tries. It didn't take more than a few minutes of usage before the screen turned black.
And right now I'm not able to get any picture at all, not even for BIOS...
So... It looks like FreeBSD killed my GPU... Great! I'm really looking forward to spend another few hundred euros on a new GPU that I barely even use to begin with!![]()
I can, however, help with the software side of things after hardware issues are eliminated.
So I will start by asking: Did you read the Handbook on how to install the correct driver for your RX 6600? If you skipped steps, then of course the driver won't load and you'll get a blank screen.
If you look for Codename of your GPU on TechPowerup.com, you'll see that it's Dimgrey Cavefish. And that is definitely present in https://cgit.freebsd.org/ports/tree/graphics/gpu-firmware-amd-kmod/pkg-plist.
Because of that, all you need to do is follow directions in the FreeBSD User Handbook (Section 5.3, graphics cards), don't skip steps or do them out of order.
Just install graphics/drm-kmod, then add the
amdgpu
driver to /etc/rc.conf, and then reboot.This can be done even if you have to SSH in from the side.
I ate a bowl of thick split pea soup with some garlic, onion, and Anaheim pepper!Please, tell me what you ate.![]()
