Hello.

I know,but it does no= t work. If I use ONLY the framebuffer argument,it works : the desktop manag= er is loaded within the vm window,but if between the bhyve parameters I dec= lare the framebuffer AND the nvidia slots,on the vm window I see the blinki= ng pointer because the output is redirected to the screen that I have attac= hed to the nvidia HDMI connector. The problem is that at the moment I can&#= 39;t use that monitor,since I'm using my PC in a different room.
I made an experiment : I have excluded all the parameters that may= be used in my old Ubuntu installation by installing Ubuntu (22.10) from sc= ratch and between the bhyve parameters I have added both the framebuffer an= d the 4 nVidia slots.

W= hen I choose "try and install Ubuntu" I see the blinking pointer = because the output is redirected to the screen that I can't use. But if= I choose "safe graphics" maybe it makes the magic. Below you can= see what are the parameters used by Ubuntu to display the installer even i= f between the bhyve parameters I have used the framebuffer and the nVidia a= dapters.


Instead below you can se= e what are the parameters used by Ubuntu to display the=20 installer if between the bhyve parameters I use both the=20 framebuffer and the nVidia adapters but without choosing "safe graphic= s" on the ubuntu boot menu.


As yo= u can see,the parameter that makes the difference is called "nomodeset= ". So,I presume that in a certain ubuntu configuration file I should a= dd that parameter....

what Im trying to do is to set the framebuffer video adapter as primary=20 graphic card on my bhyve-ubuntu vm instead of the nvidia RTX 2080 ti=20 card that I have passed through.

The script that I use to launch the vm is the following :

#!/bin/sh
setxkbmap it
vms=3D"$(ls /dev/vmm/*)"
vncs=3D"$(ps ax | awk '/vncviewer [0]/{print $6}')"

for vm in $vms; do
                session=3D"${vm##*/}"
                echo "bhyve session =3D $session"
                echo "vnc session =3D $vncs"
                if ! printf '%s\n' "${vncs}" | grep "=
;${session}"; then
                                printf 'VNC session not found,destroyin=
g ghost vms\n'
                                bhyvectl --vm=3D$session --destroy         =
                 =20
                else
                                printf 'Found VNC session %s\n' &qu=
ot;${session},no ghost vms found,not destroying them"
                fi
done

vmdisk1=3D`geom disk list | awk '/^Geom name: /{d=3D$NF} /^ *ident: (20=

For sure ,on /boot/loade=
r.conf I've added :

/boot/loader.conf

pptdevs=3D"2/0/0 2/0/1 2/0/2 2/0/3"


As I said before,I tried=
 two xorg conf files to achieve the goal. On the
first one I tried to add only the framebuffer,like this :

bu=
t it didn't work. This is the log file that shows the errors reported :=
 https://pastebin.ubuntu.com/p/Gv7wgsDR4K/
I have also rem=
oved the xorg.conf file,but it didn't work either. This is the log file=
 that shows the errors reported :


https://pastebin.ubuntu.co=
m/p/wNcfQTByQm/


Can someone give me some=
 suggestions that can help me to understand where the mistake is,please,tha=
nks.

Try to assign a lower pci slot number = to the framebuffer device than to the nvidia gpu in your bhyve command.

I'm unfamiliar with X but according to your logs it looks = like it selects the framebuffer device as primary graphics in the first pla= ce:


(--) PCI:*(0@0:7:0) ...
(--) PCI: (0@0:8:0) ...
