hi,
I have got a new laptop (asus ux410) with optimus 940MX, I've instaled bumblebee for switch with the dedicaded graphic card and processor no problem a the beginning but when i put the laptop in sleep and I wake up him the optimus command give me this

I have installed acpi_call package (see in the wiki)
bsswitch is install too
I have add in the kernel option rcutree.rcu_idle_gp_delay=1 but I don't have any files in /sys/rctree/parameter
after the wake up I do a cat /proc/module/acpi/bbswitch he is on ON (at the start up he is OFF)
so I have try to force in OFF for the same result

I have instaled too bumbledee-resume-git same mistake after
do you have already seen this problem?
Offline
I get this sometimes when my laptop suspends or wakes up while on battery,
sometimes this works
https://github.com/Bumblebee-Project/bbswitch/issues/112#issuecomment-127995337
But I have found the most reliable way is to unload the nvidia driver and load the nouveau driver, wait for a few seconds and then unload nouveau and load the nvidia driver.
Offline
don't work for me. do you just done a modprob -r nvidia / modprobe nouveau??
Offline
in more I think when optirun bug the graphic card stay on because the laptop autonomy less I need do unload nvidia driver en doing a tee /proc/acpi/bbswitch <<<OFF to have again the same autonomy
