<<TableOfContents(2)>>

== Modifying the KDM login screen ==

Customisations to the KDM login screen are made by adding a file in {{{/etc/default/kdm.d/}}} specifying variables to override the default.

Here is one example used to activate the theme in the {{{desktop-base}}} package:

{{{
USETHEME="true"
THEME="/usr/share/apps/kdm/themes/debian-moreblue"
}}}
See the code in {{{/etc/init.d/kdm}}} for information on how these variables are used.

== Using KDE "Plasma", GNOME and LXDE together ==

If you want to use GNOME or LXDE instead of KDE "Plasma", follow the [[../../Installation#The_installation_process|installation instructions]].

To install other desktop environments after installation, simply use apt-get:
{{{
 apt-get install gnome lxde
}}}

Users will then be able to choose the desktop environment via the login manager before logging in. The usage of LXDE as default on thin clients can be forced; see  [[DebianEdu/Documentation/Jessie/HowTo/NetworkClients|networked clients]] for details.

== Flash ==

The free software flash-player {{{gnash}}} is installed by default, but switching to Adobe Flash is an option. To install the (non-free) Adobe Flash Player web browser plugin, install the {{{flashplugin-nonfree}}} Debian package from {{{contrib}}}. This requires {{{contrib}}} enabled in {{{/etc/apt/sources.list}}}.

== Playing DVDs ==
libdvdcss is needed for playing most commercial DVDs. For legal reasons it's not included in Debian (Edu).  If you are legally allowed to use it, you can use the packages from deb-multimedia.org. Add the multimedia repository (as described in the following section) and install the required libraries:

{{{
apt-get install libdvdcss2 w32codecs
}}}
== Using the multimedia repository ==
To use www.deb-multimedia.org do the following:

{{{
# install the debian-keyring securely:
apt-get install debian-keyring
# fetch the deb-multimedia key insecurely:
gpg --keyserver pgpkeys.pca.dfn.de --recv-keys 1F41B907
# check securely if the key is correct and add it to the keyring used by APT if it is:
gpg --keyring /usr/share/keyrings/debian-keyring.gpg --check-sigs 1F41B907 && gpg --export 1F41B907 | apt-key add -
# add repository to sources.list - please check the homepages for mirrors!
echo "deb http://deb-multimedia.org jessie main" >> /etc/apt/sources.list
# update the list of available packages:
apt-get update
}}}

== Handwriting fonts ==

The package {{{ttf-linex}}} (which is installed by default) installs the font "Abecedario" which is a nice handwriting font for kids.
The font has several forms to be used with kids: dotted, and with lines.
