Hello Stephan,
A year a go I did try passtrhu a dedicated nvidia GTX 1650 while
using integrated intel graphics (laptop Lenovo Legion 5 15IMH05).
Windows detected card but nvidia drivers install failed at some point.
On this laptop I did setup bios to use integrated graphics so I can
passthru dedicated nvidia.
Think I will give a new try since I follow main.
Are you using laptops for this usecase?
Thanks!

Hi!
You surely mean 'newer' NVidia cards, as my GT1030 works with
FreeBSD
14.2 Host and ubuntu guest, NVIdia driver 570, (and Win guest btw)
out-of-the-box, no kernel/driver modding...

Stephan

Hello!
Oh, laptops... With this "Optimus"-called feature i am not shure if it
will work...
But i think it's worth trying.
Maybe you will need the GPU ROM.

Good luck!

Hi!
Whilst trying to get it to work, i would suggest to always shut the host
down, not only restart the guest/vm, to be on the safe side.
There may be side effects regarding the initialization of the GPU..
When you have a working setup, this may change and you may can reboot
the vm and have always a working GPU, maybe..
Regards,
Stephan
