Bumblebee not working after kernel upgrade to 5.5.5.4

Hello everyone,

I have a Lenovo P1 (2nd) with an Nvidia Quadro T2000 and Intel Graphics. To use switchable graphics I want to use Bumblebee (https://en.opensuse.org/SDB:NVIDIA_Bumblebee). After a new installation of OpenSUSE Leap 15.1 with kernel-default-4.12.14-lp151.28.36.1.x86_64 I followed the instructions of https://forums.opensuse.org/showthread.php/537906-Cuda-Nvidia-bumblebee-codecs-quot-safe-quot-way and everything worked fine.

Unfortunately, my wifi-card (Intel® Wi-Fi 6 AX200 160MHz) works only with kernels 5.1+ (source: https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html) so I had to do a kernel update:

I ran:

zypper ar -f -p 20 https://download.opensuse.org/repositories/Kernel:/stable/standard/ kernel:stable

zypper -vv dup --allow-vendor-change --from kernel:stable

uname -r
5.5.5-4.gbfcbf21-default

After that the wifi-card works, but Bumblebee does not:

optirun --status
Bumblebee status: Error (3.2.1): Could not load GPU driver

optirun glxgears
 4526.224967] [ERROR]Cannot access secondary GPU - error: Could not load GPU driver

 4526.225044] [ERROR]Aborting because fallback start is disabled.

(Both worked fine before the kernel upgrade)

However:

systemctl status bumblebeed
● bumblebeed.service - Bumblebee C Daemon
   Loaded: loaded (/usr/lib/systemd/system/bumblebeed.service; enabled; vendor preset: disabled)
   Active: active (running) since Mon 2020-02-24 16:15:48 CET; 18min ago

    Tasks: 1 (limit: 4915)
   CGroup: /system.slice/bumblebeed.service
           └─5456 /usr/sbin/bumblebeed

Trying to load the kernel module:

sudo modprobe bbswitch
modprobe: FATAL: Module bbswitch not found in directory /lib/modules/5.5.5-4.gbfcbf21-default

Please let me know if I should add more information. When booting the “old” kernel Bumblebee works fine.

All help is welcome and an (easy?) workaround to get the wifi-card working on the 4.12 kernel would also be useful. Thanks a lot in advance! (I thought of the obvious workaround to use a usb wifi adapter, but it would be great if there was an other solution.)

Best,
Luke

Hi
Your better to open a bug report about your wifi card against the kernel, they may backport the fixes to get it working for you (Will see the 5.3.x kernel in Leap 15.2)?

You need to look at using the kernel stable repo and the bumblebee kernel stable repo…

https://download.opensuse.org/repositories/X11:/Bumblebee/Kernel_stable_standard/
http://download.opensuse.org/repositories/Kernel:/stable/standard/

They currently match the 5.5.6 kernel…

And apparently you didn’t install a Nvidia driver matching that kernel…

Okay, isn’t that somewhat frowned upon? Because it explicitly says that the driver is only supported from 5.1+. One might just say: “get the new kernel…”

Upgrading to the new 5.5.6 kernel didn’t solve my problem unfortunately. However, I tried many things and what finally worked for me is using my nvidia card with SUSE Prime on a completely new install with kernel 5.5.6.

And apparently you didn’t install a Nvidia driver matching that kernel…

I really doubt that this was ever the problem. There aren’t that many different driver versions from nvidia for openSUSE. I might be mistaken though.

So even though the problem couldn’t really be resolved, I have a way that works for me. Thanks a lot for your help.
