first off i like conky - its simple
if you dont have a file called .conkyrc in your home than conky uses a default configuration out of the binary.
if you take a look at http://conky.sourceforge.net/screenshots.html
you see shots and links to .conkyrc files - grap a simple one and modify it.
by the way if you did
su -c make install
than you have conky installed, but not as a package, so
ls /var/log/packages | grep conky
would give you nothing.
slackbuilds are cool, but maybe a bit much for conky (?)
i would say in order to get a conkypackage for slackware (what is good because you simply can remove a pkg with removepkg <pkgname>) you do it by hand - its good practice.
because by default ./configure does this (do ./configure --help |more)
--enable-audacious enable audacious player support [default=no]
--enable-bmpx enable if you want BMPx support [default=no]
--enable-hddtemp enable if you want hddtemp support [default=yes]
--enable-mpd enable if you want MPD support [default=yes]
--enable-xmms2 enable if you want XMMS2 support [default=no]
so if you want xmms2 support you have to do
and than you do
make DESTDIR=/tmp/conkypkg install
than you become root and do
you have to adjust the filenames to whatever version of conky you compile etc.
if you use some strange xwm like kde or gnome, i think you have to put a line like
into your .conkyrc ...
