I bought a riser to plug in my old graphics card because I want to create a virtual machine with a passthroug GPU.
I plugged everything in, and connected 1 screen to each graphics card.
But after the loading screen, the screen goes black. I have the impression that the OS launched well, but that GNOME may have crashed, because when I plug in a USB key, I get the audio notification. I’ve tried booting my PC with Ubuntu (live USB), and it works normally.
Why does Manjaro not seem to appreciate that I’ve added a 2nd graphics card?
PS: My graphics card is an AMD RX 5500 XT and my old one is an AMD HD7850.

I have updated the kernel and the system, everything is up-to-date. But still both screen remain black.
Edit: Even with a Live USB, Manjaro doesn’t seem to handle dual graphics cards… Does anyone know if it’s possible to use 2 graphics cards on Manjaro? I don’t want to go back to Ubuntu for that … Manjaro is the first OS that doesn’t become unstable after 1 year ( I’m on Manjaro for 3 years now)
