From the original post:
Three or four days ago I installed pclinuxos kde desktop without a hitch.
Proletariat,
FullMonty is identical to: the
standard KDE +
additional drivers and software. Maybe some of the RAID-related tools cause a problem there, or more likely you have a bad burn because there are too many strange behaviors mentioned, which is not normal.
Another suggestion: since the standard KDE installs fine, install it, do a full update, and finally in Synaptic search for and install
fullmonty-light, with more info provided
here, then customize and setup the system to your liking.
good luck,
