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-lp22.214.171.124.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:
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)

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.)
