last kernel + bumblebee kmod-nvidia

Post by colone » 2019/12/25 23:51:52

Hello,
Keep going to try to have stable centos7 installation on a recent razer laptop. After recently fixed my wifi issue now I encounter a graphic card issue.
Laptop has :
- an Intel graphic card
- an Nvidia rtx2080

Before the description some background: to fix my wifi issue I must have upgrade the kernel from el-repo, so my current kernel version is:

Code: Select all

$ uname -r
5.4.6-1.el7.elrepo.x86_64
So to take advantage of the nvidia card I followed the elrepo state about bumblebee
https://elrepo.org/tiki/bumblebee

All installation goes well, except the service startup:

Code: Select all

$ journalctl -u bumblebeed.service

Dec 26 00:21:42 lap-claubry-cf systemd[1]: bumblebeed.service failed.
Neither nvidia nor bbswitch are found ...

It seems look like kmod-nvidia / bbswitch are not corresponding to the last kernel version :?:

Could you enlighten me on that?


Thanks a lot.

kmod-nvidia ONLY works with the distro 3.10.0-xxxx.y.z kernels. It does not work with non-distro kernels as they do not support the Red Hat stabel kernel ABI.

Thanks for the reply,
That means I have to choice either wifi or rtx gpu :roll:
Any idea to get both ? is it plan to kmod-nvidia works with 5.xxxxx kernel ?
What about to use official nvidia linux driver instead of kmod ?

It's impossible for ELRepo to offer a kmod-nvidia for anything other than the distro kernel as it relies on the RHEL stable KABI to function. A mainline - or any other - kernel doesn't have that stable KABI so you cannot build kmods for them.

You should be looking from the other direction: can ELRepo offer a kmod for your wireless chipset that will work with the distro kernel? Edit: I just cheked and you have the newer ax200 intel wireless chipset. I thought there was a Red Hat supplied kmod for this that should be part of the distro... checked and there was but it's for RHEL 8.

ok! that makes sense.
So if I understand well, I have to switch to centos8 to benefit of wifi kmod without update kernel from elrepo and be able to install a correct kmod-nvidia ?

Thanks for your help!

Regardless of distro - 'importing' things outside the distro repos is going to eventually clobber your system, as you've discovered.
Remember - importing/building packages will likely "byte you in the butt" come update time, long after you'd forgotten you did that! Use repos whenever possible.
