I've been running bumblebee /primus for years now but it seems that the modern versions of things want instead to use libglvnd. I have not really seen a good tutorial for how to do this yet in Gentoo so I'm hoping to find some help here. In addition to currently using bumblebee/primus
    I am still using an old nvidia-drivers-418.88 because it is the last one that worked for me with bumblebee/primus.
    I have -libglvnd set for mesa-20.0.0 and xorg-server-1.20.7 (upgrading now from 1.26)

I could be mistaken here, but I thought I was waiting for the version bump on xorg from 1.26 to 1.27 which should include whatever patches are needed to make libglvnd system work.

Has anyone gone through this transition or can someone help me figure this out?

Thanks!!

I don't know much about this kind of setup, but the libglvnd USE started showing up with >=nvidia-drivers-435 and anyone before that is currently forced to turn it off globally.

Yes, this is true. Since I am running the older nvidia-drivers-418.88 and turning off libglvnd everywhere so I can use the old nvidia drivers with bumblebee/primus. Even with libglvnd disabled, I was never successful in any newer version of nvidia-drivers working with bumblebee/primus.

So I am looking for help dumping this old way of doing things and migrating to the newer way.

I see, but just to be sure, is your GPU supported by modern drivers? nvidia drops support for older gpu in their newer drivers, and then keep "long term support" ones for older ones.

Good point. It is an nvida quadro

Code:
02:00.0 3D controller: NVIDIA Corporation GK107GLM [Quadro K1100M] (rev a1)


Looking at the nvidia release notes for supported cards https://www.nvidia.com/download/driverResults.aspx/152590/en-us I am not finding this here. Does this mean I am out of luck?[/url]

nvidia site tells me the last driver to support this gpu is 418.113, so rather than the setup being the problem is just that the gpu won't work with newer drivers at all :(

Edit: I'd recommend to just keep things as-is and disable libglvnd, likely more suitable. It should keep working just fine for a long time.

That is good to know and, from experience, 418.88 is the last on that worked for me so what I am still using. I guess I just stay with that then. :(

But from currently maintained drivers, it is actually 390.x series is the last one which has support for this card. 418 is not maintained anymore and 435 does not have the support.

On the topic of 390, it may actually still be possible for you to use libglvnd after all.

I don't know if it'll go anywhere or if anything prevents it, but see bug #711942.
