Like others have said, most of this is possible but might take a bit of work to set up. In other words, you’re doing somewhat complex things on Windows, so it’s going to get a bit complex on Linux.
I’ve done GPU passthrough using 2 graphics cards (RX 580 going to VM and RX 550 staying connected to host) for VMs on my desktop, and it mostly works. I’d recommend this tutorial for getting it set up. I had to adapt it a bit to get my AMD card working, but it got me started. I now pass through my RX 580 to 3 VMs (obviously not at the same time): Windows 10, Windows 7, and a Hackintosh VM. Although you can technically use just 1 card (leaving Linux without graphics as Windows is using the card), I recommend using dual cards. Just make sure you:
- Have a free PCIe slot for a second graphics card that stays connected to a monitor while your better card goes to the VM. (The secondary card can be a cheap card - I’d say the 1030 might be good for you. There are ways to use the better GPU to get better performance in Linux native applications when a GPU passthrough VM isn’t running.)
- Be sure that slot is in a different IOMMU group from the GPU you pass through to the VM as well as any important system peripherals like network cards or SSDs. (Just Google something like “Linux check IOMMU groups” and you’ll find a way.)
Note that GPU passthrough invites a few bugs. You can’t always return the GPU to Linux after turning off the VM, depending on the GPU. (For a while, I got this fixed and could use my card after VM shutdown, but I’ve experienced a regression and haven’t been able to figure out what happened yet). Also, after I’ve run a VM and try to turn off the host, Linux doesn’t shut down clean sometimes and I have to manually press the power button.
As for distros, I actually don’t recommend Ubuntu anymore. I’ve found a severe decline in its performance compared to other distros and its privacy standards. I personally use Debian, but would recommend Pop OS as an easier distro. OpenSUSE and Fedora are good ones as well.
I’m sorry if I dropped a bunch of new terms without explaining them well. Ask me any questions. In return, may I ask what kind of desktop this is? Is it an ATX or ITX form factor or some sort of proprietary small form factor computer by HP or Dell or something that’s going to be miserable to upgrade?
For a more professional tool, I’ve heard DaVinci Resolve also supports Linux.
I would be annoyed with how much Shotcut or OpenShot crashes, but I can’t say better of Premiere.
