The software will be the same, such as KDE etc. as the system will be "copied" from the running knoppix live system. The knoppix hardware detection is not ran after you have done the hd install. So what I recomend is to make sure all hardware is setup properly nad that you also mount any storage devices you want to use in the hd install then when the running system is copied over to hd things will be very similar to the way they were running from the live cd.

I just put a new video card in a knoopix hd install last night, and the easiest way to fix the XF86Config-4 file was to boot my knoppix cd, let it make a working XF86Config-4 file and then copy that over to my hard drive.
