Im just using a cheap Nvidia GT710. I dont need great graphics for my purposes.
I made some progress...Last night I was finally able to get a picture with GPU passthrough on Ubuntu 20.04. I had to create the VM right from the start with the GPU already set in the template. In the past I always started the install using VNC, then changed the template to use a GPU after the install was completed, but every time I try it this way I only get a black screen. Unfortunately because of the way I have my setup, starting with VNC would still be much easier.
I now have another issue though. When I do the install this new way starting with the GPU setup first, I can get a pic and do the install but after the install is complete I cant update the VM. Every time I try, my mouse and keyboard lock up and I have to force stop the VM. Then I have to change the VM to VNC to update the VM, and then change back to GPU passthrough after that. I also have no mouse or keyboard control at the UEFI shell prompt when I first try to setup any Arch based distro. So I cant install anything Arch based anymore.
I dont know when the issue started because I only noticed the issue since Unraid 6.7. I haven't made any hardware changes on my system. The only thing that has changed is the version of Unraid that I'm using, so Im not sure if passthrough is supposed to be done differently now or if its something else. I'm hoping someone from Unraid, or any experienced user, will eventually see this post and be able to help me because I have no idea what I am doing wrong.
Just bumped into this.
It has been a while since i played around with this, but the problem of your keyboard and mouse seemed something i had encountered before on a project i was working on.
Don't know if this is still the case for ubuntu 20.04, but in Ubuntu 16.04 i had the same issue of the keyboard and mouse not working when working with Nvidia grid licenses.
Was able to solve this by :
- Updating the VM , but NOT restarting it yet.
- Before restart run: apt-get install xserver-xorg-input-all
- Reboot
After doing this i was still able to use keyboard and mouse in the ubuntu vm.
But still , seeing as this was on 16.04 , not sure if this is still applicable.
