Hello, I had the same problem, but I could solved my case: Gigabyte Notebook with hybrid Intel + Nvidia GTX 765M card with PRIME not working with (K)Ubuntu 16.04 with any version of the proprietary NVIDIA driver. When prime-select switched to nvidia gives a black screen, set to intel worked. NVidia proprietary driver prime-select set to nvidia worked on (K)Ubuntu 14.04 before.
The solution that worked for me (with latest stable driver 367.57, from graphics ppa, but should work with every driver) was to change xorg.conf! The version of Xorg shipped with (K)Ubuntu 16.04 is 1.18.4, where the BusID format in xorg.conf was slightly changed in Xorg >= 1.17.2. I changed `BusID "PCI:1@0:0:0"` on the nvidia card to `BusID "PCI:1::0:0"` and similar process on the intel section and also added the LoadModule setting. Like described in an answer to a post on askubuntu. see: http://askubuntu.com/a/776527 I guess the broken id works on PRIME set to intel because autodetection in single-intel mode is much better then the Nvidia PRIME stuff. After restart it worked, but something changed my xorg.conf again to have invalid data. I'm now experimenting with deactivating gpu-manager by commenting all lines in /etc/init/gpu-manager.conf (see https://vxlabs.com/2015/02/05/solving-the-ubuntu-14-04-nvidia-346 -nvidia-prime-black-screen-issue/ ) and setting "chattr +i" for xorg.conf. and see ArchWiki: https://wiki.archlinux.org/index.php/NVIDIA_Optimus#Using_nvidia Hope this solves your problems with NVidia PRIME too! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1559576 Title: Ubuntu GNOME boots to black screen when using proprietary Nvidia drivers on a laptop with Optimus Status in gdm: Confirmed Status in Ubuntu GNOME: Triaged Status in gdm3 package in Ubuntu: Triaged Status in linux package in Ubuntu: Invalid Status in gdm3 source package in Xenial: Triaged Status in linux source package in Xenial: Invalid Bug description: Using latest Ubuntu Gnome x64 daily build with all updates installed.
