Adding a second GPU
by ZZII from LinuxQuestions.org on (#4SNYE)
I currently have 4 monitors and a TV, and want to run it all from one PC. I currently have an NVidia GeForce GTX 1060 3 GB with 3 outputs. I want to add a second GPU to run the other two screens.
I have loads of AMD cards but I know they don't play nice with NVidia cards in Linux.
I have a couple older NVidia cards but they aren't on the supported list for the 10 series driver. I have tried a 9400 GT anyway but it did not work.
Is there any simple way to get any of my spare video cards to work in Linux with the 1060?
Options I have:
GeForce 9400 GT
GeForce 9800 GT
GeForce 9800 GX2
Quadro NVS 295
Quadro NVS 420
Radeon HD 3450
Radeon HD 3870
Radeon HD 5450
Radeon HD 8570
Radeon R7 240
The machine:
Dell Precision T3500
Intel Xeon W3565 3.20 GHz
16GB DDR3 RAM
4GB SATA SSD
256GB NVMe SSD
480GB SATA SSD
1TB 7200rpm HDD
Dell 525W PSU
Fedora Cinnamon 30 x64
Thanks
