If you cannot boot then boot using a LIVE ISO, then manjaro-chroot.
If you still can boot you can skip the above.
Now change the file /etc/default/grub by adding
acpi_backlight=vendor
somewhere in the line
GRUB_CMDLINE_LINUX_DEFAULT="
after the first ".
Afterwards apply (still within chroot environment if applicable):
sudo update-grub
exit (twice) and reboot.
