I have a fresh install of Kubuntu 15.10, i have a msi GT70 laptop with optimus.
I have installed
bumblebee bumblebee-nvidia, it is absolutely needed because nouveau keeps crashing at login.
So i edited /etc/bumblebee/bumblebee.conf
# Configuration file for Bumblebee. Values should **not** be put between quotes ## Server options. Any change made in this section will need a server restart # to take effect. [bumblebeed] # The secondary Xorg server DISPLAY number VirtualDisplay=:8 # Should the unused Xorg server be kept running?

$ cat /proc/acpi/bbswitch 0000:01:00.0 ON
I putted in /etc/modules-load.d/modules.conf
So i am able to do :
$ primusrun glxinfo | grep "OpenGL version" OpenGL version string: 4.2.0 NVIDIA 304.128
But if i reboot all i have is a black screen, to get my system starting i have to login in tty1 and do:
sudo modprobe nvidia_304 sudo service sddm restart
to get the kubuntu login screen any ideas to fix that ?
Also if i replace nvidia-304 by nvidia-355 i can't boot at all : the modprobe tip is not working.
Here is my config with lspci:
$ lspci|grep -i vga 00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06) 01:00.0 VGA compatible controller: NVIDIA Corporation GK104M [GeForce GTX 870M] (rev ff)

Also there is actually a bug with i915 module on kernel 4.2 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1494903
EDIT2 (working bumblebee solution):
I have manage to make this work https://www.kubuntuforums.net/showthread.php?69190-Bumblebee-Nvidia355&p=381043
- install nvidia-355 and nvidia-prime
- select intel driver in nvidia panel and logout
- install bumblebee only (not bumblebee-nvidia)
- edit as needed /etc/bumblebee/bumblebee.conf line22 KernelDriver=nvidia replace nvidia-current by nvidia-355
- /etc/bumblebee/xorg.conf.nvidia uncomment BusID "PCI:01:00:0" as described here https://askubuntu.com/questions/29044...vices-detected,
- you can now boot under intel card and use optirun and primusrun. It is working for me so far, test with primusrun glxinfo
EDIT3: (maj 03/12/2015)
Using ppa:graphics-drivers/ppa and ppa:xorg-edgers/ppa, after an update and reboot, I had a blackscreen using 358.16-0ubuntu0~gpu15.10.2.
So I purged everything and then just installed bumblee-nvidia nvidia-358, edited /etc/bumblebee/bumblebee.conf and did sudo service bumblebeed restart.
It did work again after a reboot.
