Bugzilla Bug 168540

I have emerged rss-glx-0.8.1-r4  USE="kde sse xscreensaver -3dnow -openal". But
this time they not appers in controlcenter, instead I found them in KMenu in
"Lost & Found".
The problem is where the *.desktop files are installed:/usr/share/applications
instead of /usr/kde/3.5/share/applnk/System/ScreenSavers.
I have modified the ebuild and now is working fine

Reproducible: Always

Steps to Reproduce:
1.emerge rss-glx
2.
3.

Actual Results:  
The screensavers don't appers in controlcenter, instead I found them in KMenu
in "Lost & Found". The .desktop files are installed in the
/usr/share/applications 

Expected Results:  
Install the .desktop files to /usr/kde/3.5/share/applnk/System/ScreenSavers

I have modified the rss-glx-0.8.1-r4ebuild:
Code:

if use kde; then
      find . -name '*.desktop' -exec \
         sed -i \
            -e 's:Exec=kxsrun \(.*\):Exec=kxsrun \1:g' \
            -e 's:Exec=kxsconfig \(.*\):Exec=kxsconfig \1:g' \
            '{}' \
         \; \
         || die "couldnt sed desktop files"
# the problem is here
      myconf="${myconf} --with-kdessconfigdir=usr/share/applications"
   fi

To this
Code:

if use kde; then
      find . -name '*.desktop' -exec \
         sed -i \
            -e 's:Exec=kxsrun \(.*\):Exec=kxsrun \1:g' \
            -e 's:Exec=kxsconfig \(.*\):Exec=kxsconfig \1:g' \
            '{}' \
         \; \
         || die "couldnt sed desktop files"
      myconf="${myconf} 
#This is the solution to the problem
--with-kdessconfigdir=/usr/kde/3.5/share/applnk/System/ScreenSavers"
   fi

No, this is not the solution; that location is deprecated and shouldn't be used
anywhere. Does /usr/share/applications/screensavers work for you?

/usr/share/applications/screensavers don't work for me.
With this location I have the same problem.
There is a screenshoot:

KDE, where do you want your extra screensaver .desktop files installed by
rss-glx with --with-kdessconfigdir= ?

It's a KDE only thing, these savers work fine without the mentioned files in
other environments and in xscreensaver itself.

The paths kcm_screensaver uses to look for .desktop files seems really limited.
A quick patch to kcontrol adds the current install path for rss-glx
(/usr/share/applications/).

If you don't feel like patching, you can copy rss-glx's .desktop files into
~/.kde/share/applnk/System/ScreenSavers/ and they'll show up in the screensaver
dialog.

Note that the .desktop files kind of suck, they don't put the screensavers in
any of the dialog's categories (they are put in the root of the list instead
of, say, OpenGL Screen Savers). rss-glx needs to be patched for that.

Patch to kcontrol's kcm_screensaver

Patches kcm_screensaver to add /usr/share/applications/ to the paths searched
when looking for .desktop files (necessary for the entries being displayed in
the dialog).

KDE should follow standards from freedesktop.org.. 
http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html#variables

Yes, it should but currently it does only half-heartedly. Please file an
upstream bug for this and add its URL to this bug.

I would like to see an upstream bug filed about this issue and linked to from
here. This does look like a very minimal patch to fix an issue. It seems
unlikely to introduce bugs and allows KDE to better function within the
freedesktop.org standards.

I have applied the patch in 3.5.7 but didn't rev bump as this is an issue that
only affects a small number of users in a very minimal way. Works just fine
here and some of those screensavers are very pretty - would be a shame to hide
them from KDE users. I do agree that it would be good if they had better
.desktop files...
