I have a fresh install of ubuntu 16.04.1 (only installed today) and oddly enough I have no problems with NVIDIA drivers on my system however when switching to Intel I get a black screen.
Most of the posts I have seen are about Nvidia drivers not working but since I am only using linux for work and some video playback I dont really need the nvidia card to be working I only need Intel graphics so I can save a bit of battery power too.
My system is an Inspiron 15 7559 2016 model with HD570 Intel graphics and a GPU of 960m. As I said I have no problem with Nvidia but for some reason when running
sudo prime-select intel sudo reboot
I get a black screen after the boot up process. If I add
to the kernel options I get it to start fine but without any options for the graphics (i.e. scaling doesnt work, which is essential on a 4k screen or else everything is really really small).
I have been through a bunch of posts here and on other forums but they all relate to the nvidia drivers not working rather than intel.
I installed the NVidia and Intel drivers through the "Additional Software" tab (both are enabled; intel microcode and Nvidia) and directly after installing prime-select query returns "Intel" but after a reboot I get a blank screen unless I change back to nvidia.
I have also tried to access TTY (to see if I can find some errors from dmesg) when faced with the black screen but there is no output, I have to hold down the power button and do a hard shutdown.
Laptop specs are available here:
Its the last one on the right of the selection.
Ofcourse I could keep it running in Nvidia but then my battery drains really fast (max 2 hours with light usage). On Windows it runs normally and gives me hours of battery life (more than 4 usually).
Furthermore in Nvidia I see some screen distortion when coming out of sleep mode.
I previously had elementary OS 0.4 Loki installed (yesterday) but after no luck with that I thought maybe there was something not supported by that particular distro so I went for a clean Ubuntu installation.
I am running on kernel 4.4 and what I have seen online this is supposed to fix the issue? (I maybe mistaken). I am still a novice at linux so if there is any required logs, etc. that are required please let me know I will update my post.
Upgrading to 4.5 kernel did not help I am currently using the Intel linux graphics update tool and will update if that works.
