Bumblebee Version: optirun (Bumblebee) 3.2.1

Hi, I discovered that Bumblebee stopped working after updating my Kernel. The latest version i have installed is 3.18.3-201 and there isn't even the bumblee deamon running (calling optirun in terminal), nor can't I start it as modprobe doesn't find the bbswitch module (bumblebeed --daemon). I tried to re-install both, bbswitch and bumblebee, via yum but that didn't change anything. When i boot 3.17.7-300 from GRUB it still works and my dedicated NVIDIA GPU is turned off; but also bumblebeed --daemon displays: modprobe: FATAL: Module bbswitch not found.

I recently installed VirtualBox, following the instructions given here: http://www.if-not-true-then-false.com/2010/install-virtualbox-with-yum-on-fedora-centos-red-hat-rhel/

Besides that, i didn't do anything more unusual than yum update

Any tips appreciated.

it works for me with 3.8.0 - 3.8.5, so I guess it may be your setup. "modprobe: FATAL: Module bbswitch not found." indicates, that the required modules are not built for your kernel.

[keckelt]

It worked for over a year now (including 3.17.7 kernel) and I (think I) didn't change anything.

When the module is not built for my kernel, how can it still work?

EDIT: Just updated to 3.18.5-201 and: echo OFF > /proc/acpi/bbswitch works as expected. However, bumblebee daemon is still not running and the nvidia card wasn't deactivated automatically-

[karolherbst]

I think the issue is, that modprobe doesn't find bbswitch anymore for some reasons.. I guess bumblebee doesn't check whether bbswitch is already loaded or not :/

Does running these commands help? (as root)

dkms add -m bbswitch -v 0.8.0 dkms build -m bbswitch -v 0.8.0 dkms install -m bbswitch -v 0.8.0

[keckelt]

Thanks for the answers, I got held up in the afternoon: Manually, I can get the daemon running with:

$ sudo modprobe nouveau 
$ bumblebeed --daemon

Has this something to do with the fact that nvidia and nouveau are both blacklisted in /etc/modprobe.d/bumblebee.conf ?

DKMS commands didn't help:

$ sudo dkms add -m bbswitch -v 0.8.0
Error! DKMS tree already contains: bbswitch-0.8.0
You cannot add the same module/version combo more than once.
$ sudo dkms build -m bbswitch -v 0.8.0
Module bbswitch/0.8.0 already built for kernel 3.18.5-201.fc21.x86_64/4
$ sudo dkms install -m bbswitch -v 0.8.0
Module bbswitch/0.8.0 already installed on kernel 3.18.5-201.fc21.x86_64/x86_64

no, this is no problem at all. You should be able to run sudo modprobe nvidia at any time.

[keckelt]

Hmm, After changing /etc/modprobe.d/bumblebee.conf to:

blacklist nvidia
#blacklist nouveau

bumblebee works as expected now, i.e. Intel card is used after boot and I can use optirun.

[I use nouveau drivers, not nvidia]

[gsgatlin]

See issue #582 for using bumblebee with nouveau driver in fedora. My experiences were that bumblebee-nouveau package was required. (and xorg-x11-drv-modesetting had to be removed) But it sounds like maybe you've got it figured out now? Were you trying to use nouveau or nvidia module with bumblebee?

[keckelt]

I wasn't using the bumblebee-nouveau-package so I installed it now and reverted the changes in /etc/modprobe.d/bumblebee.conf, but the problems are the same as before. I will stick to the "solution" above and comment out the blacklisting of nouveau.

[ArchangeGabriel]

Hum, this could be autodetection not working if nouveau isn’t loaded. Should take a look at that.
