KLD nvidia-modeset.ko: depends on kernel - not available or version mismatch

[Adrien2002]

Hello,

I am using FreeBSD -current since a few weeks with nvidia driver. It was working correctly since I update with pkg update && pkg upgrade 4 or 5 days ago.

I've set "nvidia_load" and "nvidia-modeset_load" to my loader.conf and set "linux_enable" in my rc.conf.

Now, if I try to start X with nvidia driver, here's what I'll get from Xorg.log :

[ 33.729] (EE) NVIDIA: Failed to initialize the NVIDIA kernel module. [...]

And here is what dmesg says about it :

KLD nvidia-modeset.ko: depends on kernel - not available or version mismatch
linker_load_file: /boot/modules/nvidia-modeset.ko - unsupported file type

You have to rebuild /usr/ports/x11/nvidia-driver from ports, I think.

Here, for now I load it by the commands:
kdlload /boot/modules/nvidia.ko
kldload /boot/modules/nvidia-modeset.ko

Which for now fail in loader.conf, and without both, produce a blank Xorg.
But this workaround works... should be not too difficult.

Of course, YMMV ...took me a few hours of harried guesswork...

Good, I'll build it then and I come back to tell you if it changed anything.

kldload gives the same result as when it loads at boot time. The error message is coming from dmesg anyway so it's the same I load during boot or after boot.

[Adrien2002]

No, even built from ports, the problem is still the same.

I tried to don't load them in boot time, I commented the two lines then reboot. I tried to load them after with the kldload command with the path from root as you did but the message is exactly the same.
In case you ask, of course I uninstalled the package nvidia-driver from the repositories. I suppose it won't let me install a built package if it is already installed, eventually build and make the package but it will stop at the moment when it tries to install it so yes, I uninstalled it before to run "make -C /usr/ports/x11/nvidia-driver install clean clean-depends".

[Adrien2002]

Ok I found the solution to my problem, I simply built an up to date FreeBSD kernel from sources. I don't know how to update the kernel the normal way, I got used to do it like that with NetBSD and it worked so I guess it's cool.
Oh and I was able to uncomment the two nvidia_load from loader.conf, they work now.

Once in a while, or once so far, I advocate to the mailing lists that this/these procedures go into /usr/src/UPDATING and/or the pkg-message ...

[Adrien2002]

So when on FreeBSD, to update the kernel, you can only fetch it already built or build it by yourself as on other BSD instead of using a "pkg" like command to fetch it from repositories as on GNU/Linux, right ?
