Bumblebee Intel+Nvidia on 15.10 blackscreen issue
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

I have
$ cat /proc/acpi/bbswitch
0000:01:00.0 ON
I putted in /etc/modules-load.d/modules.conf
i915
bbswitch
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.
Solution 1:
As you have quite new GPU hardware you should use new NVIDIA drivers and software as well.
Replace bumblebee with nvidia-prime to switch between integrated and dedicated graphics.
Reinstall the NVIDIA drivers, but first uninstall all NVIDIA software and remove the bumblebee.
Open a terminal and execute:
sudo apt-get purge nvidia* '^bumblebee.*'
sudo reboot
When the GRUB boot menu appears : Highlight the Ubuntu menu entry and press the E key.
Add the nouveau.modeset=0 parameter to the end of the Linux line ... Then press F10 to boot.
Install the stable NVIDIA proprietary drivers from the Ubuntu repositories (does not apply to ubuntu 12.04:
sudo apt-get update
sudo apt-get install nvidia-352 nvidia-prime
sudo reboot
When you want to use the latest drivers - install them from the Proprietary GPU drivers PPA:
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-355 nvidia-prime
sudo reboot
Solution 2:
Managed to get bumblebee to work in Wily after way too much unnecessary headaches, without that nvidia-prime horribleness.
As others suspected, it's because of gpu-manager. Whatever that is, it is barfing all over the update-alternative configuration. Masking that service and reinstalling bumblebee[-nvidia] fixes all problems, now the card turns on and off via optirun as expected, and no more black screens at boot.
sudo systemctl mask gpu-manager.service
sudo apt-get install --reinstall bumblebee bumblebee-nvidia
Also make sure there's no broken /etc/X11/xorg.conf left behind.
Solution 3:
Although everything seemed to work, trying the following shows the bbswitch cannot turn off the nvidia card properly:
cat /proc/acpi/bbswitch
primusrun glxinfo|grep OpenGL
sleep 1
cat /proc/acpi/bbswitch
Then I reinstalled bumblebee-nvidia, it worked UNTIL I restart the system. After digging some more about the problem, I noticed that update-alternatives are updated after restarting the system and I noticed that gpu-manager is causing that. (simply run "sudo gpu-manager" and you'll see it is updated)
gpu-manager runs after you start lightdm. so, as a quick workaround, I disabled it.
now everything works as expected. after running something with optirun or primusrun, bbswitch turns nvidia off properly when the process exits.
To sum up, here is my summary to install everything from scratch (run it manually by reading the comments):
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get purge -y nvidia* bumblebee bumblebee-nvidia bbswitch-dkms primus
sudo apt-get install nvidia-355
#switch to intel
sudo tee /etc/prime-discrete <<< off
#reboot is recommended at this point
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee primus
#sudo gedit /etc/modules
# add the line "bbswitch load_state=0"
#sudo gedit /etc/modprobe.d/bumblebee.conf
#and make sure the following line exists
# blacklist nvidia-355
#sudo gedit /etc/bumblebee/bumblebee.conf
# change line 22 "Driver=" to "Driver=nvidia"
# change all nvidia-current to nvidia-355
#sudo gedit /etc/bumblebee/xorg.conf.nvidia
# uncomment BusID line if it is commented and make sure it corresponds to the correct BusID
#disable gpu-manager as it changes i386-linux-gnu_gl_conf and x86_64-linux-gnu_gl_conf
sudo systemctl mask gpu-manager.service
EDIT: I removed rc.local modifications because gpu-manager was running not only at runtime but also while using the system. Therefore I disabled it completely.
