SLiM - the Simple Login Manager - is currently the default Display Manager for the Manjaro Openbox (ManjaroBox) flavour.

SLiM is highly configurable with an abundance of extra themes available. Since version 1.6.2, it is suitable for less experienced users as it can now automatically detect any installed desktop environments and window managers. However, users installing SLiM manually will still need to make an amendment to the '.xinitrc configuration file for it to work properly.

Configuring SLiM to Start Desktop Environments

Tip

---

It is not necessary to take any action for Manjaro Openbox (ManjaroBox) release 0.8.8 and onwards.

Users who have installed an earlier version of SLiM (e.g. provided with the Manjaro Openbox 0.8.7.1 release and earlier) will need to manually edit both the SLiM configuration file (slim.conf) and the X-Windows initialisation file (.xinitrc) in order to enable the new auto-detect feature. Users who have manually installed the latest version of SLiM will only need to manually edit the .xinitrc file. The amendments required are themselves very quick and easy to implement.

Edit the SLiM Configuration File

The purpose of checking and/or editing this file is to ensure that SLiM will automatically detect installed desktop environments and window managers. You will need to first open your terminal in order to edit the SLiM configuration file. The syntax of the command to do this is:

sudo [text editor] /etc/slim.conf

For example, if you wish to edit the file using Geany (provided with the Openbox flavour) then enter:

gksu geany /etc/slim.conf

Otherwise, if you wish to edit the file using Gedit (provided with the XFCE flavour) then enter:

sudo gedit /etc/slim.conf

Ensure SLiM Automatically Detects Installed Environments

Once the SLiM configuration file has been opened, it will be necessary to ensure that the following line is present:

sessiondir /usr/share/xsessions/

Users who had a previous version of SLiM installed must replace the sessions command with the above sessiondir command. For example, users who installed Manjaro Openbox 0.8.7.1 or earlier should first find the following section:

# Available sessions (first one is the default).
# The current chosen session name is replaced in the login_cmd
# above, so your login command can handle different sessions.
# see the xinitrc.sample file shipped with slim sources
sessions            xfce,gnome3,kde,cinnamon,razor-qt,openbox,lxde,mate 

And make the necessary amendment so that it now looks like this:

# Available sessions (first one is the default).
# The current chosen session name is replaced in the login_cmd
# above, so your login command can handle different sessions.
# see the xinitrc.sample file shipped with slim sources
sessiondir /usr/share/xsessions/

Once satisfied that the sessiondir command is present and/or has replaced the old sessions command, save and close the file. The next - and final - step necessary is to edit and configure the X-Windows Initialisation File.

Open the X-Windows Initialisation File

Tip

---

The .xinitrc file is already owned by you, so there is no need to use the 'sudo' or 'gksu' commands to edit it.

The .xinitrc is responsible for actually starting your installed desktop environment(s). You will need to first open your terminal in order to edit the X-Windows initialisation file. The syntax of the command to do this is:

sudo [text editor] ~/.xinitrc

Don't forget the dot. For example, if you wish to edit the file using Geany, then enter:

geany ~/.xinitrc

Otherwise you could use the Gedit text editor instead, by entering the command:

gedit ~/.xinitrc

Ensure the X-Windows Initialisation File Runs Installed Environments

Warning

---

SLiM no longer seems to support a default session. It will therefore be necessary to select what desktop environment or window manager you wish to use by first pressing the <F1> key, prior to entering your username and password.

Once the .xinitrc configuration file has been opened, it will be necessary to ensure that the following line is present at the very end of the configuration file:

exec $1

Users who had a previous version of SLiM installed must completely replace both the previous case "$1" and DEFAULTSESSION= commands listed below with the exec $1 command. For example, users who installed Manjaro Openbox 0.8.7.1 or earlier should first find the following section:

DEFAULTSESSION=openbox-session

case "$1" in
    openbox) exec openbox-session ;;
     xfce) exec xfce4-session ;;
     gnome3) exec gnome-session ;;
     kde) exec startkde ;;
     cinnamon) exec gnome-session-cinnamon ;;
     razor-qt) exec razor-session ;;
     lxde) exec lxsession ;;
     mate) exec mate-session ;;
     *) exec $DEFAULTSESSION ;;
esac

And make the necessary amendment so that it now looks like this:

exec $1

To clarify for newer users, the entire .xinitrc file should now look like this:

#!/bin/sh

#
# ~/.xinitrc
#
# Executed by startx (run your window manager from here)
#

## Ensure that the D-Bus Communication System is running properly to fix
## File management, authentication, and other essential system processes

if which dbus-launch >/dev/null && test -z "$DBUS_SESSION_BUS_ADDRESS"; then
    eval "$(dbus-launch --sh-syntax --exit-with-session)"
fi


## Ensure that GTK themes are applied uniformly in the Desktop Environment

export GTK2_RC_FILES="$HOME/.gtkrc-2.0"


## Where the default Home folders have not already been created, generate them

if [ -x /usr/bin/xdg-user-dirs-update ]; then
   /usr/bin/xdg-user-dirs-update
fi

## Ensure that obmenu-generator (a pipe menu) is set to the user.
## Needs only to be run once, so last sed command hashes the sed
## commands!

sed 's/_user_/'$(whoami)'/' ~/.config/obmenu-generator/schema.pl -i
sed 's/_user_/'$(whoami)'/' ~/.config/obmenu-generator/config.pl -i


exec $1

Once satisfied that the exec $1 command is present and/or has replaced the old case "$1" and DEFAULTSESSION= commands, save and close the file. Now reboot the system for the changes to take effect.

Selecting Multiple Desktop Environments

Note

---

Again, there is no longer a 'default session', so you will have to manually pick the installed desktop you wish. This includes even where only Openbox has been installed, as it is possible to use this window manager with the KDE desktop environment.

Where two or more desktop environments have be installed (or at least just Openbox), then they can be cycled and selected by pressing the F1 key on the SLiM login screen.

Previewing Installed Themes

Thankfully, it is not necessary to repeatedly edit the SLiM configuration file and re-boot your system in order to see what the installed themes look like. More conveniently, they can instead be previewed in the terminal. To do so, once the themes have of course been installed:

1. Change to the directory that contains the themes by entering the following command:

cd /usr/share/slim/themes/

2. List the installed themes available by entering the following command:

ls

3. Preview any and all installed themes listed. The syntax of the command to do so is:

slim -p [name of theme]

For example, to preview a listed theme called mindlock, the following command would be entered

slim -p mindlock

To exit from a theme currently being previewed, simply type exit into the user name field and then press <enter>

Changing Themes

Tip

---

There may be even more themes available from the Arch User Repository.

A particularly strong feature of SLiM that has attracted many users is the abundance of varied and wide-ranging themes available for it. Moreover, these themes are very easy to set. To install all available themes for SLiM from the official Manjaro repositories, enter the following command in the terminal:

sudo pacman -S slim-themes archlinux-themes-slim

Open the SLiM Configuration File

You will need to first open your terminal in order to edit the SLiM configuration file. The syntax of the command to do this is:

sudo [text editor] /etc/slim.conf

For example, if you wish to edit the file within the terminal using nano (a standard terminal-based text editor) then enter:

sudo nano /etc/slim.conf

Otherwise - if you have installed the full version of Manjaro (i.e. not the NET-Edition) - you may find it easier to use the pre-installed gedit text editor instead. This will open the configuration file up as a document, making it easier to read and edit. To use gedit instead, the command is:

sudo gedit /etc/slim.conf

Set the Desired Theme

Warning

---

Make sure that you list the name of the desired theme correctly.

Enabling the automatic login is undertaken in the following section, located near the bottom of the SLiM configuration file:

# current theme, use comma separated list to specify a set to 
# randomly choose from
current_theme       default

To change the theme, simply replace the name of the current theme listed after the current_theme command (e.g. default) with the name of the desired theme to set. As an example, SliM has been configured to use the mindlock theme:

# current theme, use comma separated list to specify a set to 
# randomly choose from
current_theme       mindlock

Once your amendments have been completed, you can save your changes and close the configuration file by:

• nano: Press CTRL and 'x' to exit, 'y' to save, and <enter> to finish, or
• gedit: Select the 'save' option and then close the window.

SLiM Login Commands

Tip

---

This section may prove especially useful if SLiM has been misconfigured in some way!

SLiM also provides a number of basic functions in addition to logging into a desktop environment. To use these features, simply enter the following commands into the user name field:

• exit - Return to the command line
• halt - Shutdown the system
• reboot - Reboot the system
• console - Launch the terminal
