I would think this mis-reported issue will also be going on with 14.04.4 lts which will not include the so-called ubuntu-drivers-common 'fix' If interested on what really is occurring on optimus laptop & nvidia-prime see here - https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1501041
14.04.4 lts users can solve with a start up script(s) that put the display to asleep & then wake up or they can adjust the greeter time to sleep to 2 - 4 sec's. Once sleep > awakened on the greeter then the logged in session will be fine. -- 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.
