Fedora23 nvidia960m troubles

Hi! I'm new to fedora, and having somes troubles with nvidia drivers.

I have an Intel chipset and an Nvidia 960m graphic card. Since my card is optimus-compliant I installed bumblebee and it works fine (optirun glxsphere64 works). But, I have somes problems. If you don't want to know what I did to try to resolve it, directly go to the end of the post ;)

The first one and the most annoying is that I cant change brightness. I looked over the internet and two answers are usual :

1. Change the grub config to set the acpi_backlight to vendor
• Not working, as soon as I change some configuration, grub or xorg, in relation with my video card, I'm stuck during the boot process to the "start switch root" stageroot" stage
2. Change the file located in /sys/class/backlight/***_backlight
• The folder /sys/class/backlight exists but is empty

The second one is that I can't plug a dual screen. Or... I can plug one but it is not recognized by the computer. It is an HDMI port directly plugged on the graphic card.

My kernel version is 4.4.7-300.fc23.x86_64. I can notice that I have no /etc/X11/xorg.conf. As soon that I declare one, the original one with X :1 -configure` if I remember well, or the nvidia-generated one, I am stuck at the boot as I said before. I notice that it is as soon as I declare a Driver (nouveau/intel/nv/nvidia) It crashes. I searched around PCI description, drivers location (Don't know why but I can't locate the one from nvidia...), but still cant.

Sorry for the long post, but I tell all the Information I had, I think. To resume that, I can't have dual-screen and deal with my brightness. Thanks!

Hey there! I have a gtx950M card in my laptop. Here's a link to my blog: http://bumblebeesky.blogspot.com
I can change the brightness on my laptop, so setting bumblebee up this way might help you.
