Hi, couldn't find the right subreddit so decided to go with this one. I have recently been building a project pc with the single cpu Mac 5,1. My old gpu was a 5770 hd I believe and it runs unbuntu perfectly fine, and sometimes when I swap it for my new 5700 xt it boots an image. This is only sometimes though, and it's only after swapping it from the old gpu. 5700xt swapped in- boots image - I power off when done - I try to reboot on 5700xt and get no display, but it is recognized by my monitor. This is frustrating and any help would be appreciated!
