I started out with a plain ArchLinux installation following the guide in the Arch Wiki. I must admit that I started the installation late at night and that caused me to do some things wrong. So I had to redo some of the steps. If i had followed the guide then the installation of Arch and i3 would only have taken around 15 minutes(if not even less). The only real problem I ran into was with the touchpad. It just did want to work in the standard configuration. It turned out that i needed to install the psmouse-elantech package. After the installation it registered fine and i could start configuring it. The touchpad is actually a clickpad and supports multitouch. I have setup mine to do palm detection and emulate middleclick (so i can paste in my terminals).
Since i am not running any DE i did not have the gnome/kde session to take care of multimedia keys for eg play pause volume or changing the brightness of the laptop screen. The solution for this was simple:
bindsym XF86MonBrightnessDown exec xbacklight -dec 10
bindsym XF86MonBrightnessUp exec xbacklight -inc 10
in my ~/.i3/config did the job.
I am using the “super” key (on the Galago it has a ubuntu log on all other keyboards a windows logo) as a modifier for most functions in i3. So if i want to open up a new terminal i would use super+enter. On my work computer i have pre set a lot of key combinations to make my life easier. However on the Galago keyboard there is no right super key so i used xmodmap to rewrite the menu key, that i never use anyway:
keycode 135 = Super_R
I must say that I am really happy with my current setup. There is not one thing in the hardware or on my wishlist that did not get to work. Even the HDMI output just worked.
