LinuxMusicians

Hello I would like to thank you again for the work done !
I'm working to Customize the livedvd for make discover linux on music for french students.
I've made some modification like:
french language, keyboard fr, user in audio group, installing lilypond, frescobladi, fluidsynth-soundfont-gm (loading in Qsynth by default in /usr/share/kxstudio ... and /etc/skel), vkeybd.
I add 4 desktop by default.

My others questions are:
By default, Cadence is on Dummy and I would like that it is set on Alsa when I launch the livedvd. I saw in .config/Jack that this file is rewriting by jackdbus ... I don't understand where Cadence write its driver information ... (there is noting about that in .config/Cadence/*)
A stupid problem:
When I install KxStudio on a machine my personnal directory is by default my desktop :/ How can I do (if it's possible by commande line or file configuration) to have directory desktop in Desktop ?

Thanks for your answer

Ok why not (I use script also to go inside with chroot, and to produce iso),
is it a bash script or a python script (for me all that I did work fine) ?
The live dvd that i try to produce is only for me and some students to produce a live dvd that start with all out of the box (language, french kbd, qsynth with soundfonts inside, numlocks activate, audiogroup for all users) without any produce command line.
I will not distribute it on the web and will respect your work and perhaps also help kxstudio

What about the 2 lasts questions (Home vs Desktop and alsa vs dummy in cadence) ?
