    Bumblebee + Nvidia355

    Has anyone manage to make bumblebee work with nivida-355 or any nvidia driver at all. It made it work on session but a reboot gives me a blackscreen.
    I tried following http://rajat-osgyan.blogspot.fr/2015... fresh install.
    I posted a thread on http://askubuntu.com/questions/68992...ckscreen-issue

    So i can use nvidia-prime with nvidia-355, but using the nvidia card if i reboot i get a blackscreen, i have to reinstall with
    Code:
    apt-get install nvidia-prime nvidia-355 --reinstall && sudo service sddm restart
    .
    This manipulation is needed everytime i boot. This is annoying specially when you know bumblebee is actually working n 15.10 but that black screen omg.

    Can some one reproduce this ?

    You can see details of my laptop on the askubuntu thread. I don't think it is needed to repost these here.

    Hard to read through, and some info linked is in Italian. The bickering at the end is an added bonus.

    I have an optimus laptop that would boot to a blank screen if using the proprietary Nvidia drivers. Looking at the above thread, it looks like the screen is blanking at the login screen for some, no matter what login manager is used.

    For me, despite the blank screen, I could simply type in my password, and hit enter, just as I normally would. A workaround is to enable autologin, or figure out a script to blank and unblank the screen as an autostart item. This didn't work for me, probably pebkac.

    I thought this had been fixed, but I can't recall last time I rebooted my laptop lol. I'll have to check when I'm back home.


    I haven't tried bumblebee just yet.

      The author of the blog http://rajat-osgyan.blogspot.fr/2015...nd-latest.html, just answered me that there is actually a bug on 4.2 with i915 module screwing up here. I'm also looking through your italian link.

      EDIT:
      I tried the following kernels :
      v4.2.5-wily/
      v4.1.12-wily/
      v4.1-wily/
      v3.19.8-vivid/

      I could not make one of these work. Still got a black screen. I think i915 won't load.
      The nouveau driver is crashing, but i managed to use it by using the kernel recovery mode, the select enable networking in the menu and hit ctrl+c and hold it, you will see that sddm greetingg will start i be able to use graphic session with i assume nouveau but without crash.

      Still i do not understand what bug is causing all this trouble this is all confused.

      EDIT2:

      I have finally found how to make this work :

      1 install nvidia-355 and nvidia-prime
      2 select intel driver in nvidia panel and logout,
      3 install bumblebee only (not bumblebee-nvidia),
      4 edit as needed /etc/bumblebee/bumblebee.conf,
      line22 KernelDriver=nvidia
      replace nvidia-current by nvidia-355
      6 /etc/bumblebee/xorg.conf.nvidia
      uncomment BusID "PCI:01:00:0"
      as described here http://askubuntu.com/questions/29044...vices-detected,
      7 you can now boot under intel card and use optirun and primusrun. It is working for me so far, test with primusrun glxinfo
