Coming from arch where i was unable to control brightness no matter what i tried, i realized that by using the nvidia-390 driver in ubuntu everything is working fine....BUT i have random crashes of the system. When I am using the nouveau drivers everything is fine BUT i do not have any control over the brightness of the screen. This is a hybrid laptop and i have intel graphics and nvidia quadro P1000 Currently I am using the nouveau drivers Picture showing the 2 drivers available
Also please note that the intel graphics is not recognized at all.
Some information about my system
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1cbb (rev a1) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 8429 Flags: bus master, fast devsel, latency 0, IRQ 255 Memory at e8000000 (32-bit, non-prefetchable) [size=16M] Memory at a0000000 (64-bit, prefetchable) [size=256M] Memory at b0000000 (64-bit, prefetchable) [size=32M] I/O ports at 4000 [size=128] Expansion ROM at e9000000 [disabled] [size=512K] Capabilities: <access denied> Kernel modules: nvidiafb, nouveau

I have also attempted to use the brightness-controller application but it has no effect.
How can I either fix the brightness using nouveau drivers or fix the random crashed with the nvidia driver?
