This is not a support thread, I just figured I would share what I have learned after searching around a lot. On my current computer I have an AMD gpu, specifically the Radeon RX 5700 XT, and there are some issues with it. It is rare, and extremely random, but sometimes during gaming my screen will simply turn green and the computer locks up. I can't do anything and simply have to force reboot it. I can go for a week or more without experiencing the issue, or I might see it with just a couple of days in between. It has only happened while gaming so far. At first I was worried I had a defective card and I might need to get a new one. But when I started searching for this issue, I realize that a LOT of people have the same problem, even on Windows. I have seen multiple suggestions on how to fix it, and I figured it would be best to try out one thing at a time. For now, I have disabled Dynamic Power Management. I can't really know if it worked because of the random nature of this issue, but if I don't see this problem again for a couple of weeks then I'll assume that was the fix. I will be sure to report back here if I see the issue, or if I go for a couple of weeks without problem. To disable DPM, you need to add: radeon.dpm=0 as a kernel parameter to your bootloader.
