Acer V5 753g (Intel Haswell / Nvidia GT 750m dual GPU) Bumblebee

Question

I think I am fighting several issues here, altough I might have fixed one already. Up to this point I managed to disable the nvidia gpu, using the proprietary driver and bbswitch, but bumblebee is not working.
Okay first, I could isolated an issue with acpi, by following instructions in this bug report https://github.com/Bumblebee-Project/Bu … issues/460. To be exact it made me install a kernel module, code and install instrutions are described here: https://github.com/Bumblebee-Project/bb … ack-lenovo (After the bug report the author of this code was generous enough to add my model to the source code, so midifications weren't neccesary any more).
Now after a reboot the gpu is disabled, but as soon as I run optirun (which fails) I am not able to disable it again
I know the exact same issue is discribed in the bumblebee arch wiki page, but none of the workarounds fit my situation.

Answer 1

Your issue seems to be similar to what I had to face with the Razer Blade 14" (similar hardware as well).
Goto: https://bbs.archlinux.org/viewtopic.php?id=173356 and see the instructions to get graphics to work, see if it applies (summarized: run linux-ck and set rcutree.rcu_idle_gp_delay=2 in the kernel parameters).
I haven't tried undoing this in more recent updates because I haven't had the time to mess with it---it is possible that it has been fixed, although the thread following my and possibly your issue at nvidia doesn't give any indication of that:
