I have a functioning optimus system that works perfectly from boot. However, if I suspend the system and wake it, bumblebee fails to switch cards. Only a reboot will fix the problem, restarting bumblebeed does nothing.
Issue seems similar to https://github.com/Bumblebee-Project/bbswitch/issues/140 but the approved workaround kernel parameter does not resolve the issue. It seems that the issue is that the nvidia driver loading when the system goes to sleep, and then not unloading when it wakes, but it is hard to tell.
Console output with the suspend point marked.

Don’t have an Optimus laptop no more, but you should have a .conf file for bbswitch in /etc/modprobe.d/ . Can you post the content of that file ( something like 50-bbswitch.conf )
