Hello there,
I just installed Arch successfully on my Acer Aspire V3-571G, which has two graphics cards: Intel(disabled) and Nvidia(I already installed the mandatory driver packages). I used systemd-boot as bootloader(so those grub-solutions I found so far don't apply to my case).
"lspci | grep VGA":

"xbacklight":
No outputs have backlight property

Could please anyone tell me what to do to:
Adjust the brightness
Be able to adjust the brightness via the laptop Fn-keys?

Those 'grub solutions' you mention aren't grub specific, you can change kernel parameters no matter which bootloader you're using.

Thank you once more, slithery for helping me.
I mounted the EFI-partition onto /boot and edited my arch-boot-entry so that the options end in:
acpi_os_name=Linux acpi_osi=
As described here(post #9). I don't know whether the first attribute has to be set too(too long of a day to try that out now) but it works now.
