I am not sure about the gnome session. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1507676 Title: Nvidia-Prime not switching from intel to nvidia leading to a black screen Status in ubuntu-drivers-common package in Ubuntu: Fix Released Status in xserver-xorg-video-intel package in Ubuntu: In Progress Bug description: STEPS: 1.
