The bbswitch module is only loaded by the prime-select systemd service (which in turn call /usr/sbin/prime-select) if prime-select operates in Intel mode ('prime-select intel' or 'prime-select intel2'). That service (eventually loading the bbswitch module in the cases mentioned above) is called at the very end of the boot process, just before the Display Manager is spawned.
Old versions of the suse-prime package did not pull bbswitch (you had to use the suse-prime-bbswitch package for that) but the new version does as it combines both packages.
The use of bbswitch to disable a PCI device (the NVIDIA card) can be dangerous and not work everywhere. Though it works on my laptop with a Pascal NVIDIA GPU, on all kernels. The suse-prime package update made all users use bbswitch now (again, only in Intel mode) which is probably not a good idea.
I will create a bug report for the upstream project.
Thanks for taking care, Michael! https://github.com/openSUSE/SUSEPrime/issues/70 -- You are receiving this mail because: You are on the CC list for the bug.
