+### Intel backlight
+Probably you won't need this if you use `xbacklight`, but if for some reason xbacklight doesn't work, you can use intel_baclkight:
+Allow the `video` group
+```
+/etc/udev/rules.d/backlight.rules
+
+ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="intel_backlight", GROUP="video", MODE="0664"
+RUN+="/bin/chgrp video /sys/class/backlight/intel_backlight/brightness"
+RUN+="/bin/chmod g+w /sys/class/backlight/intel_backlight/brightness"
+```
+
+### English international keyboard
+Run
+```
+# setxkbmap -rules evdev -model evdev -layout us -variant altgr-intl
+```
+Or persist it on the xorg settings
+```
+/etc/X11/xorg.conf.d/00-keyboard.conf
+
+Section "InputClass"
+    Identifier "Keyboard Defaults"
+    MatchIsKeyboard "yes"

+```
+/etc/pacman.conf
+
+[universe]
+Server = https://universe.artixlinux.org/$arch

+
+### Optimus-manager for hybrid-GPU laptops
+You will need the Universe repository for this
+```
+$ sudo pacman -S optimus-manager-<init> <DM>-optimus-<init> optimus-manager-git
+```
+And then enable the `optimus-manager` service.
+Example with OpenRC
+```

+$ sudo rc-update add optimus-manager
+```
