Openbox
Initial setup
Start by booting Alpine (see these instructions on how to do that)
Enable Community Repository
We need the Community Repository available for access to the Openbox packages. Instructions are available on the Repositories page.
Install packages
Install the basic packages for a minimal installation:
# apk add openbox xterm terminus-font
xterm is needed so you have a way to access the terminal in X. There are alternatives but this is the classic. Terminus is needed because without any fonts, you will not be able to see any text in OpenBox.
Configure xorg-server
On most systems, xorg should be able to auto-detect all devices. However, you can still configure xorg-server manually by launching:
# setup-xorg-base
Configure user
To make Xorg work as normal user you need to add user to these groups: video, input.
# addgroup <username> input
# addgroup <username> video
acpid
If you installed your Alpine Linux as a VirtualBox or VMWare guest, you might find it handy to be able execute an ACPI shutdown.
# rc-update add acpid
Set Openbox as the default WM
$ echo 'exec openbox-session' >> ~/.xinitrc
Copy the config files to your home folder
$ mkdir ~/.config
$ cp -r /etc/xdg/openbox ~/.config
Edit Openbox settings
You can now edit the Openbox settings for your user by editing the files located in ~/.config/openbox
The Openbox configuration details can be studied on the Openbox wiki.
Start X
$ startx
