mplayer slow to start

I upgraded my ubuntu recently (Intrepid -> Jaunty). And mplayer (medibuntu rulez) proved very slow to start: like waiting for something after displaying "GNOME screensaver disabled". A little strace investigation revealed that mplayer was spawning "dcop kdesktop KScreensaverIface", which got stuck connecting to some file socket.

A quick fix is to start dcopserver by hand. Some googling suggests to install the kdelibs package, which I did but I don't know yet if it is enough to automagically fix the problem (I still have to restart from fresh to see).

Stupid ubuntu screensaver config

The default gnome configuration tool in ubuntu (Intrepid, Jaunty, ...) for the screensaver is largely incomplete. Install the xscreensaver package and configure it the "old" way (with xscreensaver-demo). However, this will NOT be enough, because gnome overrides part of its settings when it starts its own screen saver. So you will have to look at ~/.xscreensaverrc and update the config for your favorite screen saver in /usr/share/applications/screensavers/<your_screensaver_here>.desktop. For example, for me, the Exec line for glslideshow in the desktop file looks like:
Exec=glslideshow -root -duration 25 -pan 30 -fade 4

And the picture configuration is taken from my ~/.xscreensaverrc file.
