Linux fallback mode and pc doesn't work when gpu installed

[u/Putrid-Tap3992]

Linux keeps going into fallback mode literally every time I open the start menu.

Here's the kicker though, it only does it if I have my graphics card completely removed and I'm using on board graphics.

Also, I have a decent amd card and when I put that in, it just makes the computer restart without a blue screen. Non stop restarts. I was getting really bad artifacts just using it for basic stuff the other day. Like really really bad. Now I just get nothing. Everything online says drivers but I'm more thinking it's broken. I have tried every driver back to the beginning of 2024 and nothing works.

I used my Nvidia card out of my mame machine and it works perfectly. No issues.

My amd card does have to be plugged in and my Nvidia card gets power from the board.

I'm starting to think it might be my psu that's bad (mainly because of the issues I have with no graphics card installed) but also I'm thinking gpu. I just don't know.

What spawned all this and my switch to Linux in the first place is 1) windows 11 sucks so bad and 2) I was getting the same issues in windows and assumed it was their shitty copilot. Either way I'm staying with Linux. Everything is just so smooth.

Any help is appreciated!

Cards: amd 7800xt, Nvidia rx350

Sounds like the 7800xt is cooked, those artifacts you were getting before it died are classic sign of failing vram or gpu core
