Hi all. I recently installed Arch on my new laptop and it was quite a pain. When I tried to boot the installation medium, I got a blank screen. In order to fix this I had to set the "nomodeset" kernel parameter in grub and then it booted. However, after installing, I am still confronted with this problem and I'd like to get the laptop working without having to set "nomodeset". The exact specs of the laptop are:
Processor: i7 6500U (Skylake)
Integrated Graphics: Intel HD 520
Discrete Graphics: Nvidia 950M
Maybe the issue has something to do with the Integrated graphics or the discrete gpu? Preferably, I'd like to have the laptop able to start X with Bumblebee working properly. I'm a bit of a newb at this so if you need any more information, I'd be glad to provide it. Any help is greatly appreciated. Thank you in advance.
EDIT 1: The issue appears to be with the integrated graphics. Dmesg after boot to black screen is posted below. Still not sure how to fix it.
EDIT 2 - SOLUTION: The HD 520 integrated graphics issues are fixed in the latest kernel release (thanks _banach_space for pointing me to the latest release), linux-mainline 4.5rc1-1, so simply install the package from the aur. In order to get bumblebee working for graphics switching, you will also need to install the the nvidia-mainline, bbswitch-mainline, and nvidia-utils-beta packages from the aur. If you experience wireless issues where the wifi chip appears to be hardware blocked after installing the mainline kernel, it is a known issue with the wireless chipset and a workaround is found here: http://ubuntuforums.org/showthread.php?t=2181558.

You can try whether
modprobe.blacklist=nouveauOR
i915.modeset=0prevents the black screen. This should tell which one has issue.

Ok, so it turns out that it's the integrated graphics causing problems.
i915.modeset=0allows me to boot to a login prompt. However, I also tried logging in when the screen is blank and i managed to blindly get a dmesg out as follows (this is only from where the errors starts to the end of the dmesg):

There's no such thing as "fall back on nouveau or something". Different drivers work for different devices, and your devices doesn't work that way. You might want to report the bug to upstream.

Had identical problem with HP Envy 13 (similar config, though there's only integrated graphics chip). It's an issue with Intel HD 520:http://www.spinics.net/lists/intel-gfx/msg83618.html. Installing linux-mainline 4.5rc1-1 fixed the problem for me.

Thank you so much! I installed mainline from the aur package and now my system is working normally. It did take a bit to compile the whole kernel, but no more than about an hour. I will mark this as solved and post the solution in the first post.
