Static screen after installation

Hello everyone.

I just received an AMD 6800 RX card. I know these cards are having problems with Linux at the moment. However my card won’t display anything, not a black screen, its more like static.

I guess my question is how do I get the card to display or at least software render so I can run updates (Kernel 5.10 and other graphics related items) so that I hopefully can at least boot to my desktop. I’m ok with not having full support at the moment but eventually will be gaming with Steam Proton like I was before with my Nvidia card.

What does this entail? Can you switch to a TTY by pressing Ctrl+Alt+F4?

Its just a bunch of static on my screen, looks like static snow on TV with no antenna reception. I can’t link to a pic of it or embed it in this post.

I’ll try Ctrl+Alt+F4 after my reinstall, gonna try it one more time.

No go with your suggestion. Still just static. Guess I’ll have to wait until support is baked in.

Can you rule out hardware defect?

Can you try running a different kernel? Kernel 5.10 just has so many issues. I can’t even run it on my 5700 XT.

Well the issue is I am suppose to use kernel 5.10 which includes support for the AMD 6800 RX. The card is just too new. I got it working under Ubuntu 21.04 to play games in Steam. But I still am unable to see anything on the screen when booting in Manjaro. I guess I’ll wait until my card is supported out of box.

Curious question, are you using 1 or multiple monitors?

1 on display port 3 atm

I tried to use my old nvidia card, install manjaro and update kernel and updates and mesa-git but no go. I think mesa-git is messing things up. I see it removes anything to do with mesa amd/radeon.

Yeah, maybe it’s an issue with the git version.

If you’re sure it’s DP-3 (mine is DP-0 / DP-1 / DP-2), try this as a kernel parameter and see if it does anything:


I HAVE to use video=DP-0:2560x1440@60 video=DP-1:2560x1440@144 video=DP-2:2560x1440@60 or else I get a weird static screen on both Kernel 5.9 and 5.10 with my 5700 XT (or sometimes I get a kernel panic, if I have more than 1 monitors plugged in, which is a known issue)

I have 5700 XT and 5.10 kernel, works perfectly.

That’s good for you. Though a lot of others including me have issues.
