LinuxQuestions.org - (Solved) Bumblebee "Cannot access Secondary GPU, secondary X is not active"

Solution:
apparently even though nvidia is selected as driver in the bumblebee.conf, somehow he still tries to access it, to prevent that i installed a package to blacklist the nouveau driver:

xf86-video-nouveau-blacklist-noarch-1.txz

http://slackware.osuosl.org/slackwar...t-noarch-1.txz

tbh i have read about that blacklist fix somewhere earlier, so it was me just being stupid again :doh:

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

I am trying to get bumblebee working and followed the guide on the wiki
http://docs.slackware.com/howtos:har...nvidia_optimus

Everything went perfect untill i tried to actually run bumblebee.
that results in following error no matter what application i want to start with optirun:

Code:

optirun glxspheres

[ 3941.903881] [ERROR]Cannot access secondary GPU, secondary X is not active.



[ 3941.903995] [ERROR]Aborting because fallback start is disabled.

running with debug to get something out of it:

I guess optirun somehow cannot create a secondary X, but i dont know why.

bumblebee.conf:
