You probably miss some package.
I suggest you use slackpkg (instead of slapt-get) to install every not_yet_installed package but those included in kde and kdei sets.
1) uncomment one mirror in /etc/slackpkg/mirrors in. Be careful to use one matching your version *and* architecture.
2) edit /etc/slackpkg/slackpkg.conf to configure it to your taste
3) run in that order:
Code:
slackpkg update
slackpkg slackware # or slackpkg slackware64 if you run a 64 bit version
You will be presented with the list of all not yet installed packages. All you have to do is check the ones you'd like installed (or uncheck the ones you don't want, depending on slackpkg.conf settings) and click OK
