Failed to start Load Kernel Modules after bumblebee installation

English Hardware
#1

I followed suse’s tutorial on how to install bumblebee step by step on the newly installed 42.1 system.

After installation, I have got these boot errors

~ # journalctl -b -p err

I need to use steam, which uses primusrun instead of optirun. And what is that kernel module load error?

Assuming that you followed the tutorial to the last word, maybe your initrd was not refreshed; try to open a terminal and as superuser issue:


dracut --host-only --force

That should rebuild the initrd with the new Nvidia kernel modules and hopefully fix your problem.
Please write back if that is not the case. Good Luck!

#3

If this is to use Steam on the NVIDIA, be prepared to get very happy :D. Bo Simonson packages “suse-prime”. It allows you to run your entire X-session on either the Intel or the NVIDIA.
Here’s the OBS page with instructions, I followed these on my Optimus based laptop and it works great. https://build.opensuse.org/package/show/home:bosim:suse-prime/suse-prime

Compared to optirun and primusrun it’s a huge improvement. IMHO.

#4

I’ll try it when I get back to the machine.

I did some further research and think maybe I should keep using bumblebee instead of prime, which need switch between intel/nvidia with session logon/off. When you say it’s a huge improvement, do you mean the performance? Don’t they use the same NVIDIA properties’ driver?

#5

I did a dup for plasma5 repo and after restart, the kernel module error is gone. Primusrun works too now.

#6

Nice to know, maybe a refresh to the initrd was part of this last dup…
RE bumblebee performance, you might be interested in this thread
](https://forums.opensuse.org/showthread.php/510130-Poor-performance-of-NVIDIA-driver-on-quot-Optimus-quot-laptop) Bumblebee has a delay of maybe 4-5 ms when copying the graphics buffer from Nvidia to Intel for display that might be a concern for gamers; I didn’t try suse-prime myself (yet), so I cannot comment on the performance advantage, if any.

Many with openSUSE are recommending “suse-prime” instead of Bumblebee as it has better written scripts.

See: https://build.opensuse.org/package/show/home:bosim:suse-prime/suse-prime
