I need a FreeBSD15 machine with Gnome gui and would like to use a VM for that. I think that Gnome needs a graphic card so I plan to assign the Nvidia 1030 card I have available in my TrueNas Scale ElectricEel-24.10.2.2 system.
So I did start downloading the actual FreeBSD15 iso and created a zvol for the VM.
Defined the VM including the Nvidia 1030 card and started the VM. Not working
So I removed the Nvidia card from the defs and started the VM again,
Now I can install FreeBSD. After doing so I changes the sshd config to allow login and added nano and sudo.
Than I did create a snapshot 
However the system is working without gui. So I installed Gnome (pkg install gnome) that did not work.
I noticed I had to install a video card driver and setup xorg. That did still not work, among other things probably because a video card is needed.
So now I added the Nvidia card driver and added the nvidia card to the VM.
The VM does not boot …
So I need help because I do not know how to get the VM with Gnome running.
Below some actions I did take (without the needed result 
)
##The following command can be used to identify which graphics card is installed in the system:
pciconf -lv|grep -B4 VGA
% pciconf -lv|grep -B4 VGA
louisb@:~ $ pciconf -lv|grep -B4 VGA

Install the nvidia driver
sudo pkg install nvidia-driver
sudo sysrc kld_list+=nvidia-modeset

pkg install xorg
sudo sysctl kern.evdev.rcpt_mask=6
To make it persistent across reboots, add the following to /etc/sysctl.conf:
sudo pw groupmod video -m
kern.evdev.rcpt_mask=6
Install Gnome
pkg install gnome
GNOME requires /proc to be mounted. Add this line to /etc/fstab to mount this file system automatically
proc /proc procfs rw 0 0
