Solved Trying to get GTX 980 working with Xorg

P

pikadevs

Hey guys, I'm currently installing freebsd in a kvm virtual machine, with a gtx 980, however, I'm unable to get Xorg working as it errors with "no screens found (EE)" when i try startx.

Currently, I have done:

pkg install nvidia-driver
nano /etc/rc.conf
-> added the line kld_list="nvidia nvidia-modset"
-> added the line linux_enable="YES"

Xorg -configure
then tried startx, to get that error.
(tried rebooting)

Also, the display output is currently only showing in virt-manager, not on the screen that my gtx 980 is plugged into, I'm assuming this is a sideffect of the same misconfiguration. On my windows passthrough VM, the display output also shows on the monitor plugged into my gtx 980.

Sorry, I'm very new to freebsd - does anyone know what I've done wrong? Thank you.
 
Thank you for the welcome elgrande! I'll give that link a look, and follow it - hopefully that fixes the issue, and I'll report back on what it does
CuatroTorres, I am not sure what guest additions is, I have a linux host, and I am using a KVM virtual machine. My host has two graphics cards, and I am putting 1 in my virtual machine, the same way I do it with my windows virtual machine
I am using qemu/kvm so I'm not sure if that driver link is applicable to me, but the gtx 980 is still supported by nvidia's latest drivers which I have installed in the freebsd virtual machine.
 
I have just gone through this guide with the required steps (removing my previous Xorg -configure result) and sadly the same result still happens of no screens found
Is there any way I can see all the PCIE devices in freebsd, like I can in linux? Just to ensure the 980 is actually being picked up in the VM

Edit: I've just gone ahead and installed pciutils and ran lspci -nn and my gtx 980 is found, which is the expected output so I don't think that's the issue there

Did you create the /usr/local/etc/X11/xorg.conf.d/driver-nvidia.conf file?

pciconf -lv
 
Oh, I (we?) misread.
If it is running in KVM, the driver must fit the "virtual graphic card" KVM exposes (not the hosts graphic card).
 
Can you post your Xorg.0.log? cat /var/log/Xorg.0.log | nc termbin.com 9999

I'm trying to get the gtx 980 working inside of it - I have passed through the gtx 980 into the virtual machine so that it has full access to the gtx 980
It's seen in the VM as shown in my previous edit, but it's currently not doing anything otherwise I would also have a display on my secondary monitor (plugged into the gtx 980) rather than just the virt-manager spice display

My host has two graphics cards - an rtx 2080 ti and a gtx 980
I prevent the gtx 980 from being interacted with the host, and pass it through into the VM in which the VM now has full control of it

You probably need to add a BusID to the driver section. It finds two graphics cards and doesn't know which is which.

I see, thank you for the information, that may be because there's also a built in VM 3d graphics driver (alongside the passed in gtx 980)? Also unsure how that would be pci, the 10de one is the gtx 980
Do you know any links that could should me how to add the BusID to the driver section?

As far as I understand, you are running FreeBSD in a Virtual Machine.
That normally means, the guest does not access the host's graphic card. It accesses a virtual graphic card which the virtualization solution provides. (there are exceptions like having a dedicated graphics card only for a single virtual machine, but I do not guess this is the case here)

Oh i see what you mean, I am the latter case where I have a dedicated graphics card only for the single virtual machine, as mentioned before

Thanks for the link! I've gone through it, and added my BusID as pci0:0:9:0 (the one that the output told me was my 980) however it still complains about more than one primary device
Do i need to also add the VM igpu in there? I've currently only done the NVIDIA one since that's the only one I want to use (alternatively, is it possible to remove the spice graphics from the VM?)
 
Oh sorry, somewhere in the back of my mind I read VirtualBox. Does not apply.
Make sure the GPU is not used by the host.
