I've downloaded the kde packages from current. I looked at the script file that was in the directory of the kde packages, and it said I should upgrade the packages, then install the packages, just to make sure everything got installed.

When I tried to start kde, it says "could not find kdeinit" or something of the sort. Then, because of this, I just went in and removed all of the kde packages, and qt. Then, I installed the new packages again, but this time using the included shell script. All of the packages installed fine, but I tried to start kde and the same thing happened. By the way, I'm pretty sure that, before I reinstalled all of the packages, I deleted any reference to kde in the system. Removed the .kde directories for all users including root, removed /opt/kde. I might have missed something, but I'm pretty sure i got it all.

Still, same problem. Anybody have this sort of problem when upgrading packages to current?

Thanks,
Brian

I had the same problem (with 11.2) until I used linuxpackages & as always make sure you check dependencies.
Check the KDE version in current from slackware.com and then look for the same version of KDE at www dot linuxpackages dot net or slackbuilds dot org . you may need to reinstall the packages to return kde back to where it is on a fresh install. I had to reinstall what came with slack11.2 then do an upgradepkg *.tgz and (installpkg *.tgz for any new packages).
The current (test version) may not have everything thats needed. also you may want to check out the readme file for upgrading, you should be on the right track in removing all that is known of KDE then reinstalling.

KDE has been moved from /opt/kde to /usr so if your configuration files supposed to launch the KDE are still refering to something like /opt/kde/bin/kdeinit instead of /usr/bin/kdeinit, it might the reason of your problem.
