Bugzilla Bug 142197

.desktop files should go into /usr/share/applications/ and nowhere else ...
currently the ebuild uses an old install path (checked 0.8.1-r2):

$ qlist rss-glx | grep desktop
/usr/share/applnk/System/ScreenSavers/skyrocket.desktop
/usr/share/applnk/System/ScreenSavers/helios.desktop
/usr/share/applnk/System/ScreenSavers/hufo_smoke.desktop
/usr/share/applnk/System/ScreenSavers/hufo_tunnel.desktop
/usr/share/applnk/System/ScreenSavers/sundancer2.desktop
/usr/share/applnk/System/ScreenSavers/plasma.desktop
/usr/share/applnk/System/ScreenSavers/hyperspace.desktop
/usr/share/applnk/System/ScreenSavers/solarwinds.desktop
/usr/share/applnk/System/ScreenSavers/fieldlines.desktop
/usr/share/applnk/System/ScreenSavers/matrixview.desktop
/usr/share/applnk/System/ScreenSavers/flocks.desktop
/usr/share/applnk/System/ScreenSavers/biof.desktop
/usr/share/applnk/System/ScreenSavers/flux.desktop
/usr/share/applnk/System/ScreenSavers/euphoria.desktop
/usr/share/applnk/System/ScreenSavers/cyclone.desktop
/usr/share/applnk/System/ScreenSavers/spirographx.desktop
/usr/share/applnk/System/ScreenSavers/busyspheres.desktop
/usr/share/applnk/System/ScreenSavers/colorfire.desktop
/usr/share/applnk/System/ScreenSavers/lattice.desktop

Fixed in -r3:

>>> /usr/share/applications/hufo_smoke.desktop
>>> /usr/share/applications/busyspheres.desktop
>>> /usr/share/applications/cyclone.desktop
>>> /usr/share/applications/solarwinds.desktop
>>> /usr/share/applications/flux.desktop
>>> /usr/share/applications/lattice.desktop
>>> /usr/share/applications/matrixview.desktop
>>> /usr/share/applications/colorfire.desktop

>>> /usr/share/applications/skyrocket.desktop
>>> /usr/share/applications/flocks.desktop

That seems OK but KDE does not show the screensavers in KDesktop configuration
dialog or the Control Center. In my limited experience, they are only listed
when the .desktop files are installed in

/usr/kde/3.5/share/applnk/System/ScreenSavers
$( kde-config --prefix )/share/applnk/System/ScreenSavers

The locations are the same, but the second line addresses future versions.

When installed to /usr/share/applications, you can see that the screensavers
appear at the KDE menu's Lost & found submenu. The locations I specified in my
previous comment are standard to KDE; take Slackware Linux as an example.

You can check that the above locations are standard to KDE by typing

tar -xf /usr/portage/distfiles/kdeartwork-3.5.5.tar.bz2
cd kdeartwork-3.5.5
grep --recursive ScreenSavers .

The results are below:

Really, thanks for your attention.

x11-misc/rss-glx is not a KDE app; and the location was wrong regardless KDE or
non-KDE anyway. This bug is closed.
