Hi,
i have a clean install of Xubuntu 15.10 on a Asus UX303UB notebook. I have added the xorg-edgers ppa as well as the graphics-drivers-team ppa to my sources and updated the system. I then install & configure bumblebee and nvidia-361 driver from graphics-drivers-team ppa. After reboot lightdm goes dark, and i cant even switch to a console. When i login via ssh i see in dmesg:
[ 3.384002] NVRM: GPU at 0000:01:00.0 has fallen off the bus.
[ 3.384085] NVRM: A GPU crash dump has been created. If possible, please run
NVRM: nvidia-bug-report.sh as root to collect this data before
NVRM: the NVIDIA kernel module is unloaded.

I tried to add “rcutree.rcu_idle_gp_delay=1” into kernel load options as suggested here: https://wiki.archlinux.org/index.php/bumblebee#Failed_to_initialize_the_NVIDIA_GPU_at_PCI:1:0:0_.28GPU_fallen_off_the_bus_.2F_RmInitAdapter_failed.21.29 to no avail.
In Xorg.0.log i see:
[ 6.004] (II) NVIDIA dlloader X Driver 361.28 Wed Feb 3 14:48:10 PST 2016
[ 6.004] (II) NVIDIA Unified Driver for all Supported NVIDIA GPUs
[ 6.004] (II) modesetting: Driver for Modesetting Kernel Drivers: kms
[ 6.004] (++) using VT number 7
[ 6.004] (II) modeset(G0): using drv /dev/dri/card0
[ 6.004] (EE) No devices detected.
Otherwise i would suspect this is because of a wrong BusID declaration, but in /etc/bumblebee/xorg.conf.nvidia i have it:
Section "ServerLayout"
Identifier "Layout0"
Option "AutoAddDevices" "false"
Option "AutoAddGPU" "false"
EndSection
Section "Device"
Identifier "DiscreteNvidia"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BusID "PCI:01:00:0"
Option "ProbeAllGpus" "false"
Option "NoLogo" "true"
Option "UseEDID" "false"
Option "UseDisplayDevice" "none"
