I have a system with intel graphics and nvidia k2100m. I was running nvidia-358 and nvidia-prime.
I updated to the newest intel drivers yesterday and now on boot I get an error about my xorg.conf being incorrect. If I uninstall nvidia entirely everything boots just fine (i can use nouveau and intel still). I tracked that down to https://bugs.launchpad.net/ubuntu/+source/ubuntu- drivers-common/+bug/1419507 which apparently people thought the issue was related to gpu-manager but Alberto Milone says is related to xserver-xorg-video-intel which led me to this bug. I am not sure if my bug is exactly the same cause or not but I am willing to do anything to help figure this out... It is very frusterating being unable to use my nvidia drivers. -- 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.
