Hello to everyone. what Im trying to do is to set the framebuffer video adapter as primary graphic card on my bhyve-ubuntu vm instead of the nvidia RTX 2080 ti card that I have passed through. What I want to do really is to use both the graphic adapters,but the primary should be the framebuffer and…

What happens If,instead of passing the intel gpu,I want to pass the gtx 1060 (choosing the intel gpu as first and default on the BIOS instead of the 1060),and I use it in modesetting and the 2080 ti as a PRIME render offload ? is the configuration that I’ve posted correct ? Will it work as is or I s…

For nvidia2nvidia PRIME, you don’t need the modesetting driver, just driver 470+, see https://forums.developer.nvidia.com/t/ubuntu-20-04-not-able-to-run-6-7-monitor-setup-with-one-x-screen/200904/2?u=generix though in that case, pci2pci transfers are involved instead of pci2sysmem in the intel cas…

which xorg.conf file should I use in this case ?

If you disable the virtual graphics, none.

can you elaborate more ? what do you mean ? Should I use the BUS id value on the modesetting field ?

ok. anyway I’m more interested to pass correctly the intel gpu. Asap I will try to do that. Take in consideration that it works already for a lot of users. I don’t know why it doesn’t for me. I’m in contact with the developer who created the patches to enable it. I should install freebsd from scratc…

I’m trying to understand why, because an error,my intel graphic card is not accepted by any bhyve / vm based on Linux,but it works if the OS is Windows. The error given is : bhyve: Warning: Unable to reuse host address of Graphics Stolen Memory. GPU passthrough might not work properly. bhyve: gvt_…

As you know, gpus have a video bios, the vbios, which gets started by the system bios (sbios, uefi firmware), booting the gpu. Those vbioses have two parts, the old vga bios and the new efi framebuffer. Depending on what is set in the system bios (csm en-/disabled), either the vga bios or the efi fr…

On the BIOS of my PC I don’t have a CSM entry related to the GPU. If I remember correctly the firmware of my Nvidia graphic cards can be configured as BIOS or UEFI using an external tool that I don’t remember the name. But I don’t know if it works even for my Intel GPU. In addition,why the intel gpu…

I'm failing trying to configure the framebuffer as default graphic adapter and the nvidia geforce RTX 2080 ti as PRIME render offload

If there are only the two nvidia gpus in the vm and no virtual graphics adapter, no xorg.conf is needed. Xorg autoconfig.
