In the case of the reported ASUS laptop it could be a problem related to the BIOS version, but not in my case. And truely not in the case of a lot of other users. Simply make a google search with "nvidia prime ubuntu black screen" and filter by date "last month". You will find tenth of results with people discussing about this problem. E.g.: - https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1362848 It seems that one solution is to enforce "sleep and wake-up" of display after switching to nvidia. Other people are still mentioning the switch to modesetting and deactivation of gpu-manager. Another solution seems to point out switching to gdm, which ends up in avoiding the "sleep/wake-up" problem related to light-dm. I'm very disappointed that this bug report is handled like an individual problem. A lot of people have this problem and the workarounds are really nasty. It's an important feature for every user owning a laptop with an discrete nvidia card, because on one hand it's reducing the power consumption drastically and on the other hand enabling the full potential of a discrete card.
