I get black screens on the simplest games and even the snapping tool

Sorry for opening a ticket here. I tried searching for various answers online but came up short.

I am new to Linux. But sadly I got a problem with my graphics card straight out of the gate.

For some reason my system is running on the iGPU and I can't seem to figure out why. There's already so much to learn and this is throwing me for a loop.

So there's three likely scenarios.
Either there's an option somewhere that switches to/from iGPU that I can't find.
The OS hastruble reading or recognizing the dGPU.
Or the graphics card is DoA.

I had a friend help me but they had to leave. We verified I got the correct bazzite install (AMD), we ran updates, made sure to unplug and replug the power supply to the card.

I hope someone can help me with this.

My specs as follows:
CPU: AMD Ryzen 7 7700X
GPU: AMD Radeon 9070 XT

Solution

What do you mean choose? The 9070xt is a desktop GPU right?

You choose iGPU or dGPU on a desktop based on where you’re plugged in. Dynamic switching like on a laptop isn’t really a thing

Indigo 🔜 NFCOP•6/28/25, 1:17 PM

Yeah that's what's so weird about it. I got my screen plugged into the video card.

Maybe I'm just hoping agaisnt hope it isn't dead.

RocksoC•6/28/25, 1:40 PM

What are you noticing? Does it say it's using integrated graphics? Or are you having very poor performance?

Indigo 🔜 NFCOP•6/28/25, 1:48 PM

I got very poor performance. Only the simplest games like Slay the Spire play and I am even noticing lag there. Did some more digging with my friend and the card seems to be noticed but driver seems to fail to load?

I'm going to try to flash a different linux distro on a stick and see if that works.

Indigo 🔜 NFCOP•6/28/25, 2:47 PM

Same issues in Fedora. It seems to not get recognised.

In the meantime we also completely removed the video card and plugged it back in to be sure and changed the PCIE slot to gen4 in bios

Try disabling the igpu in bios and installing lact to see if the voltages and frequencies etc are doing what they're supposed to do

biebel•6/28/25, 3:15 PM

Oh, and if you're using a riser cable, mount it directly for diagnosing

Indigo 🔜 NFCOP•6/28/25, 3:55 PM

already disabled igpu in bios. I'll look into lact. I don't got a riser cable.

biebel•6/28/25, 4:02 PM

With nvtopnvtopyou can see the pcie connection it's using

Indigo 🔜 NFCOP•6/28/25, 5:09 PM

Sorry I can't take screenshots because the whole pc black screens when I do so.

biebel•6/28/25, 6:09 PM

It's running at the correct pcie gen and lanes. Did you manage to run lact?

Indigo 🔜 NFCOP•6/28/25, 6:31 PM

Yeah here is the info screen

biebel•6/28/25, 6:36 PM

Those all seem correct. try running a gpu stresstest on occt for example and see if the power usage etc acts normal. Is your psu sufficient for the card?

Indigo 🔜 NFCOP•6/28/25, 6:38 PM

It's a CX750. I used pcpartpicker to pick matching items so I figured it would be sufficient?

Indigo 🔜 NFCOP•6/28/25, 6:41 PM

Okay I downloaded occt but I'm unsure which program to open it with.

biebel•6/28/25, 6:41 PM

Depends on the exact model I think. 750 is the minimum for my pulse model, but oc models are probably higher. I'm not sure what the symptoms would be when they're insufficient. Shouldn't matter on the desktop I think.

biebel•6/28/25, 6:42 PM

just doubleclick it. Might need to make it executable first, can't remember.

Indigo 🔜 NFCOP•6/28/25, 6:43 PM

oh yeah I keep forgetting to make it executable. Sorry new to Linux.

Indigo 🔜 NFCOP•6/28/25, 6:46 PM

Running now

biebel•6/28/25, 6:47 PM

do the 3d adaptive one instead. It's weird that your gpu clock is so low on every screenshot tho

Indigo 🔜 NFCOP•6/28/25, 6:48 PM

Yeah I figured I'd run CPU too just in case

Indigo 🔜 NFCOP•6/28/25, 6:49 PM

Indigo 🔜 NFCOP•6/28/25, 6:50 PM

Fans of the GPU are not running but it's probably because it's at a cool 46C/114.8F

biebel•6/28/25, 6:52 PM

it does seem to have more than 1hmz now. Try to run it on steady and extreme, so we can see if it boosts and draws power as it should

Indigo 🔜 NFCOP•6/28/25, 6:55 PM

Steady with heavy load. Fans are finally spinning

Indigo 🔜 NFCOP•6/28/25, 6:57 PM

Now doing extreme

Indigo 🔜 NFCOP•6/28/25, 6:58 PM

Extreme load. Sure drawing power now.

biebel•6/28/25, 7:00 PM

Yeah, power draw and boosts speeds are right. Really weird that you're having those performance issues and glitches :/

Indigo 🔜 NFCOP•6/28/25, 7:00 PM

Yeah I have been pulling my hair out. Had a DoA motherboard before, then trouble with the DDR RAM later and now this. This PC is cursed.

Indigo 🔜 NFCOP•6/28/25, 7:01 PM

So heavy testing is fine

Indigo 🔜 NFCOP•6/28/25, 7:01 PM

but

Indigo 🔜 NFCOP•6/28/25, 7:01 PM

I can't play anything more intensive than slay the spire

Indigo 🔜 NFCOP•6/28/25, 7:01 PM

I can't even screenshot

Indigo 🔜 NFCOP•6/28/25, 7:01 PM

wth is this

biebel•6/28/25, 7:07 PM

More as a sanity check than anything else, what outputs do you get from switcherooctlswitcherooctl and kscreen-doctor -okscreen-doctor -o

Indigo 🔜 NFCOP•6/28/25, 7:09 PM

I like sanity checks because I've been losing mine

Indigo 🔜 NFCOP•6/28/25, 7:10 PM

Most of this is beyond my shallow depth.

biebel•6/28/25, 7:13 PM

This all looks correct. Time for trying something not quite sane. If you have a DP cable, try with that

Indigo 🔜 NFCOP•6/28/25, 7:13 PM

That's the problem. I don't have one.

Indigo 🔜 NFCOP•6/28/25, 7:15 PM

I got two screens and one tablet all HDMI. WaS meaning to buy adapters to convert them into DP after everything was sorted.

Solution

biebel•6/28/25, 7:16 PM

:/ See if disabeling adaptive sync makes any difference in the weird screenshot glitch

Indigo 🔜 NFCOP•6/28/25, 7:23 PM

I've been looking, but I am not sure this older monitor has adaptive sync?

Indigo 🔜 NFCOP•6/28/25, 7:25 PM

Reminds me that I haven't checked with a different monitor, I still got my newest monitor connected to my old dying pc

Indigo 🔜 NFCOP•6/28/25, 7:25 PM

lemme switch those

biebel•6/28/25, 7:26 PM

I saw vrr on automatic in the screendoctor output.

biebel•6/28/25, 7:27 PM

See if setting it to disabled makes a difference

biebel•6/28/25, 7:28 PM

Testing with a different display is a good idea too yeah

Indigo 🔜 NFCOP•6/28/25, 7:29 PM

omg that is it!

I get black screens on the simplest games and even the snapping tool
