SLiM is a Simple Login Manager (also known as a display manager) which is lightweight and simple to configure.
Install
Simply add the slim package with:
apk add slim
I should imagine you'd also want some kind of desktop installed too, like Gnome or XFCE
Configure & Test
The SLiM configuration file is at /etc/slim.conf and it is heavily commented, so I'll not add any info about it here unless asked to (in the discussion function for instance). Before making any changes it is recommended to backup the default configuration file with:
cp /etc/slim.conf /etc/slim.conf.original
Then you can modify /etc/slim.conf and easily copy the default configuration back if you run into trouble:
cp /etc/slim.conf.original /etc/slim.conf
To immediately test slim, do
rc-service slim start
and you should be presented with a login screen, branded for Alpine linux!
Login with your normal user credentials (avoid using a desktop as root) and you should reach your desktop.
Once you've tested it works, start SLiM at the default runlevel:
rc-update add slim
Note: You should disable any other display manager you have running to prevent them both launching. For example, to prevent lxdm from starting at boot use:
rc-update del lxdm
Extra Login Commands
When on the SLiM login screen, you can use:
exitas a username to return to a shell promptrebootas a username and the root password to reboot the machinehaltas a username and the root password to power down the machine
Troubleshooting
If you are using a .xinitrc file (usually located at ~/.xinitrc, slim will read from this and you will need to ensure you have a line to execute your desktop environment. This is usually the last line of the file. For example:
.... exec startxfce4
if you are using an Xfce, or:
.... exec gnome-session
if using GNOME.
If you don't do this, or you make a mistake with your typing, you'll probably get an error like failed to execute login command
Themes
Simply add the slim-theme package with:
apk add slim-themes
All theme which are available on your system are located at /usr/share/slim/themes
ls /usr/share/slim/themes
You need to modify /etc/slim.conf to change the theme:
sudo vi /etc/slim.conf
Search for current_theme and choose one of the available themes.
