I've installed on my notebook with a intel- and a secondary nvidia-GPU bumblebee and the nvidia-driver.Ive installed the proprietary bumblebee (bumblebee-nvidia and primus) as well as the nvidia driver (nvidia-driver).Unfortunately, everytime I'm trying to use the optirun-command I run into the following error:[  940.032794] [ERROR]Cannot access secondary GPU - error:               [XORG] (EE) Screen 1 deleted               because of no matching config section.[  940.032839] [ERROR]Aborting because fallback start is disabled.Why is this approaching? I've not seperated /etc/X11/xorg.conf-file where I've entered a screen 1 section or so.EDITAdditional InformationsOS and Kernel: Debian (4.6.0-1-amd64)dmesg output after running optirun glxinfo:[   60.060368] bbswitch: enabling discrete graphics[   60.139924] nvidia: module license 'NVIDIA' taints kernel.[   60.139930] Disabling lock debugging due to kernel taint[   60.148818] [drm] Initialized nvidia-drm 0.0.0 20150116 for 0000:02:00.0 on minor 1[   60.148822] NVRM: loading NVIDIA UNIX x86_64 Kernel Module  352.79  Wed Jan 13 16:17:53 PST 2016[   82.677037] systemd[1]: apt-daily.timer: Adding 6h 59min 17.494951s random time.Additional my log-File-Dump from /var/log/Xorg.8.log: http://pastebin.com/raw/RbB5hg6h
