GNOME
Prerequisites
Installing packages
Install basic desktop system and gnome packages.
# apk add gnome
If you want to, you can also install additional GNOME apps for a more complete GNOME experience with:
# apk add gnome-apps
Graphical login
To start the GDM display manager and login with your user, you need a user other than root for this to succeed, since GDM will refuse starting if no user accounts (meaning accounts with a UID >= 1000) are available.
rc-service gdm start
Once you have verified that it actually works you can make gdm start up at boot:
rc-update add gdm
Enabling terminal apps
If you want to use the gnome-terminal/other terminal applications you will need to install bash. If you want a typical bash setup also enable bash completion:
# apk add bash
# apk add bash-completion
Troubleshooting
If you are unable to login, check /var/log/gdm/greeter.log, there may be output there from X to indicate failed modules, etc.
If logging in from GDM returns to logging screen, try
# apk add bash
