‎packages you need to emerge:

New page

== '''Guide to get RSS screensavers working and configurable on ether 32bit or 64bit Sabayon Linux:''' ==

Unfortunately the kdeartwork package doesn't detect that we've installed xscreensaver so we have to edit a couple of files to get around that
if later on it does work then congrats!!

'''what we are going to do:'''
Rebuild kdeartwork-kscreensaver so it builds kxsconfig & kxsrun needed for xscreensaver and RSS
install rss-glx
run my python script to fix the .desktop files

== packages you need to emerge: ==
we may as well emerge everything now and have it over and done with

{{Console| <pre class="clear">emerge --fetchonly =kdeartwork-kscreensaver-4.3.1 rss-glx xscreensaver</pre>}}
{{Note| Up to you if you want to install all these packages as we will need to do that at least to rss-glx and xscreensaver for the script later on}}

we need to copy our kdeartwork file to our home dir and extract for editing
{{Console| <pre class="clear">cp /usr/portage/distfiles/kdeartwork-4.3.1.tar.bz2 ~/
tar -xjf kdeartwork-4.3.1.tar.bz2 kdeartwork-4.3.1</pre>}}

and then edit three files:
{{File|kdeartwork-4.3.1/kscreensaver/kxsconfig & kxsrun| <pre class="clear">bool KXSConfigDialog::create()
{
QWidget *main = new QWidget(this);
setMainWidget(main);
QVBoxLayout *topLayout = new QVBoxLayout(main);
topLayout->setSpacing(spacingHint());
QHBoxLayout *layout = new QHBoxLayout();
topLayout->addLayout(layout);
layout->setSpacing(spacingHint());
KVBox *controlLayout = new KVBox(main);
controlLayout->setSpacing(spacingHint());
layout->addWidget(controlLayout);
((QBoxLayout*)controlLayout->layout())->addStrut(120);

KConfig config(mConfigFile);

QString xmlFile = "/doesntexist";
#ifdef XSCREENSAVER_CONFIG_DIR
xmlFile = "XSCREENSAVER_CONFIG_DIR"; -------!! CHANGE THIS FOR BOTH KXSCONFIG AND KXSRUN
#endif </pre>}}

{{Note| This fixes kxsconfig and tells it where to find our configuration files /usr/share/xscreensaver/config change the file location of the last xmlpath to the one here and make sure not to put an ending slash }}

Remove the check for xscreensavers and remove the if statement around kxsconfig and xsavers:
{{File| kdeartwork-4.3.1/kscreensaver/CMakeLists.txt| <pre class="clear">find_package(KDE4Workspace)

if(KDE4WORKSPACE_FOUND)
macro_optional_find_package(OpenGL)
macro_log_feature(OPENGL_FOUND "OpenGL" "API for developing portable, interactive 2D and 3D graphics applications" "http://mesa3d.sourceforge.net" FALSE "" "Provides 3D screensavers.")
add_subdirectory( kdesavers )
add_subdirectory( kpartsaver )
add_subdirectory(kxsconfig)
add_subdirectory(xsavers)

elseif(KDE4WORKSPACE_FOUND)
message(STATUS "kscreensaver can't be compiled. Please install kdebase/workspace before to compile it (need kscreensaver.h)")
endif(KDE4WORKSPACE_FOUND) </pre>}}

Now to compress and replace the original kdeartwork with our edited one
{{Console| <pre class="clear">mv /usr/portage/distfiles/kdeartwork-4.3.1.tar.bz2 kdeartwork-4.3.1.bak
tar -cjf ~/kdeartwork-4.3.1.tar.bz2 ~/kdeartwork-4.3.1
cp ~/kdeartwork-4.3.1.tar.bz2 /usr/portage/distfiles/ </pre>}}

We have to trick portage and create a new digital signature for our file
{{Warning| You MUST do this otherwise it will see your file as corrupted and create a checksum failure}}
{{Console| <pre class="clear"> rm /usr/portage/kde-base/kdeartwork-kscreensaver/Manifest
cd /usr/portage/kde-base/kdeartwork-kscreensaver/
ebuild kdeartwork-kscreensaver-4.3.1.ebuild digest </pre>}}
{{Note|this may emerge some packages, let it as long as it is not kdeartwork-yourversion
and if it is you've done something wrong}}

now emerge kdeartwork like normal
{{Console| <pre class="clear">emerge kdeartwork-kscreensaver</pre>}}
{{Note| It will say it can't find any xscreensavers don't worry it doesn't matter}}

So now we should be ready to install RSS-GLX and/or xscreensaver
{{Console| <pre class="clear">emerge rss-glx xscreensaver</pre>}}

'''and for the finishing touch save as foo.py run this script as root # python foo.py'''
