i have a feeling this aint the right list for this kind of problems, but i couldn't find any better.
I downloaded
debian-testing-amd64-kde-CD-1.iso 18-May-2009 11:08, selected "Desktop environment" during setup, and i got no kde (no 3.5, no 4.2). Then i tried to manuly apt-get install kde from the cdrom, which ended up in a non-working, broken kde.
I've been using debian and kde for a while now, and still dont know what to do.
