Between FC3 and FC4 the packages were split.
In FC3 it was only xscreensaver and an upgrade installs
xscreensaver-base only. In fact a new install of FC4 also only installs
the base package unless you select everything.
In FC4 to get the whole thing you need
xscreensaver-extras
xscreensaver-base
xscreensaver-gl-extras

Some have said that there are switch settings in alsamixer to turn on
the headphones and off the sound. I have not seen that problem but
maybe it is related to which sound system you have. Carefully check all
the different controls in alsamixer and for those that are just toggles
(several in mine) it may be a single setting and not a slider that fixes
the issue.
