X doesn't start: Nvidia 940GX

I'm trying to get X configured on a Thinkpad 25. This laptop has a GeForce 940GX graphics device and I'm running 12.0--CURRENT r3270038.

I tried the guide here, but the install of x11/nvidia-driver package failed due to "no linux compatibility in kernel". Next I referred to this page in the handbook, which led me to install the nvidia driver from the ports collection. That succeeded, but I'm still not sure if there the required Linux support is in place.

Next, I created /usr/local/etc/X11/xorg.conf.d/driver-nvidia.conf with:

Code:
Section "Device"
   Identifier "NVIDIA Card"
   VendorName "NVIDIA Corporation"
   Driver "nvidia"
EndSection
Trying to start X with startx resulted in the following X.org log:

Not sure what the no devices and screens errors mean. I tried a couple of other things that I ran across, but they did not help:

1.) Adding linux_load="YES" to /boot/loader.conf
2.) Adding kern.vty=vt, also to /boot/loader.conf

The first one seemed to make sense in the context of needing Linux compatibility. The second one is voodoo I do not understand (but it was mentioned in one of the Handbook pages). According to NVidia's website, this graphics device is supported. What else can I try to make it work?

Thanks,
Chuck

Unless you need CURRENT for other hardware, it might be worth trying with 11.1 I don't think (but am not sure) that you would need the kern.vty=vt in this case. (I don't want to give bogus advice, and am too tired to check it right now, but it seems to me I've only ever needed to add that with Intel cards).

CURRENT is more useful when you have an Intel or AMD card, as many that are newer than 3 years old or so are not supported in RELEASE. As you you have an NVidia card, you will almost certainly have better luck sticking with RELEASE

In my experience, the guide you linked to usually works (for RELEASE).

It's been the default for a while now, there's no need to set it explicitly. But it doesn't hurt if you set it.

I was using CURRENT because this machine has an Intel 8275 wireless chip and support for that was added only recently. I could try RELEASE. The machine has an Ethernet interface (supported by the em driver). Less convenient, long term, but workable for a test.

With, CURRENT, I got a little farther by specifying a BusId.

I used this info from pciconf:

Code:
vgapci1@pci0:2:0:0:     class=0x030200 card=0x224617aa chip=0x134d10de rev=0xa2 hdr=0x00
    vendor     = 'NVIDIA Corporation'
    device     = 'GM108M [GeForce 940MX]'
    class      = display
    subclass   = 3D
to add this to the Device section:

Code:
        BusId "PCI:2:0:0"

As indicated in the above, /var/log/messages does contain something interesting:

I tried a couple other values for the BusId, such as "0:2:0" (which was printed early in the Xorg.log) and one that was intended to be invalid "3:0:0", just to see what would happen. Both of those resulted in an Xorg.log similar to the original one.

Yeah, only one NVIDIA, so maybe BusID is irrelevant here. Linux modules seemed to be loaded even if I removed the the line from loader.conf. Not sure what's up with that.

Given all that: it turns out it has an Intel HD 620 chip as well. After these steps, X started:

- Install drm-next-kmod package
- Add kld_list="/boot/modules/i915kms.ko"
- remove all the files from /usr/local/etc/X11/xorg.conf.d (there was only the one).
- reboot

I have a feeling that the NVIDIA could be made to work, but not sure how to interpret those errors.

Ah, I didn't realize it had an Intel card, or I would have aggravated SirDice and told you to use CURRENT. I haven't had a dual video laptop so have no experience with them, but the newer (with a loose definition of new--at this point we're talking 3 years old and newer) laptops often require CURRENT to have any sort of decent performance. I have a little page (that I don't think you need) about FreeBSD and later intel cards, http://srobb.net/freebsdintel.html but the only thing I'd mention from it is to redo your kernel to use the GENERIC-NODEBUG kernel, as the default CURRENT kernel will give reduced performance.

I didn't realize it either, but pciconf -lv showed it. I think this is a Kabylake-based laptop and, according to the graphics support page, that requires CURRENT and using drm-next-kmod. Seems like it works fine, but my needs are modest here: mostly terminal and Emacs work with some web browsing.

Some laptops allow you to disable one or the other card in the BIOS. That might provide a solution.

Mixing the Intel driver and the NVidia driver is going to be problematic in any case. The NVidia driver replaces a couple of Xorg libraries, I'm really unsure how this would interact with the Intel driver that assumes the original Xorg libraries.

Where do I add this?
In case anyone else needs it:
I added the line to /etc/rc.conf
kld_list="/boot/modules/i915kms.ko"
As a result of experimenting with an external display, I currently have:
# Trying all three
kld_list="/boot/modules/i915kms.ko nvidia nvidia-modeset"
