Some distros do a swell job of backporting the needed things, but only so many of them and so many more manufacturers (with secrets).

WIFI quirk:
$ cat /etc/modprobe.d/rtlwifi.conf 
options rtl8723be ant_sel=2
# ip link set wlan0 down
# modprobe -r rtl8723be
# modprobe rtl8723be ant_sel=2
# ip link set wlan0 up

Sorry about the tech babble, it's just how my brain works. Give me a computer at age 10 and talking to humans is hard. Basically the wifi driver is under going a rewrite to "auto" detect which one of only half used antennae are available. Until that completes, the choice is yours and the only way to know if you made the right choice is if it's "better" than the other choice(s) in practice. For hardware orientated types, open the thing up move the wire to the "other" choice (aka default), reassemble. The hardware is wired for TWO antennae, the manufacturer only provided and connected ONE.

Backlight quirk:
FILE: /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi=force acpi_backlight=vendor"
Where "quiet" was the ='s value before edit. Resulting in (after update-grub):
$ cat /boot/grub/grub.cfg | grep -i backlight
	linux	/boot/vmlinuz-4.12.0-1-amd64 root=UUID=11111111-1111-1111-1111-111111111111 ro  quiet acpi=force acpi_backlight=vendor
Basically pass parameters to the kernel via the bootloader. Or ignore the ability to change the brightness of your display and use the HDMI out and turn OFF the laptop LCD in X by:

$ xrandr --output eDP --off

Benchmarks (aka performance) improves if you only use ONE of the display outputs. That's about the only quirks I've run into so far, for my not that same as yours hardware, beyond needing something newer than debian stable (stretch) for the GPU to play nice. Although the framebuffer default did work alright in jessie (xserver-xorg-video-amdgpu is not available in jessie), just hardly worth having a quad core with 8GB ram at that performance level. More like 7.6GB ram if you want to get technical. Where xserver-xorg-video-amdgpu is available in stretch, but not new enough to be glitch free if gaming.

$ sudo apt-get install xserver-xorg-video-amdgpu
