Hello,
I recently installed a new GPU a 6700 XT and have been having issues. I never had issues at all with my old GTX 1060 GB after making sure I had the right driver. I got AMD because I was supposed to not have to deal with that. I am running a fresh install of Ubuntu now just to make sure nothing I did broke anything.

Firstly, there are flashes of black screen pretty consistently in a couple different spots on the screen. https://imgur.com/Z7VzsC7 They don't show up using screen capture so I took a video. This gets absolutely infuriating after a while. I have not been able to find any info on this, but I have a Windows partition where I have no issues so I know my card isn't just dead.

Secondly,
I have what seems to be a common enough issue but I have not been able to find a solution that works well for me. When running most games, they crash X and I have to restart it from another tty or just reboot the computer because even that doesn't work sometimes. This crash is extremely consistent and usually happens within minutes of loading a game, sometimes within seconds. The main game I have been trying this with is Total War Warhammer II if it makes a difference, but like I said it happens with plenty of other games like KSP and Middle Earth Shadow of War. The main error seems to be
I've found some other forums saying that a different kernel version might work but always versions that are too old to be compatible with my 6700xt. The other things I found were to do with mesa and I tried them before the fresh install but I could've just done it wrong.

I don't usually use forums so I'm not sure the best way to post the rest of the journalctl or what else might be helpful but I'm available if you could let me know.

Any help with either issue would be appreciated. I really enjoy linux and would hate for this to be the reason I can't use it anymore.

or install diff firmware or maybe a diff distro.

Have a read of this post please as it shows what some have done to succeed. They do not specify they are gamers (I am not on PC) so you you will need to check your vulkan-info
and vkcube

you will need the amdgpu firmware if not already installed too

you will notice the name of the device is navy flounder and that is the firmware that you need as discussed here

Hello wildpjah, & welcome to LQ.

New video card, big issues. With new cards, use the proprietary AMD drivers if they exist. Be prepared for trouble. If they don't work, you harvest and provide logs, you file bugs with AMD, and they will patch the drivers. Then you update drivers and test again. It's a PITA, but you have the problem, and they don't. Then there's peace for a while.

Then they stop doing proprietary drivers, and your card is supported by the OSS kernel drivers. Then there's a drop in performance, perhaps a bug or three, but usually peace for a longer while.

Give us full machine/driver/distro details.
