different users

[Doug Pollard]

    At the present time I have two hard drives one with ubuntu (sb1) on 
it and the other with ubuntu studio  (sb2) .  I have Cinelerra on ubuntu 
first drive but not on  Ubuntu studio as there seems to be some problems 
that as yet i am not competant to overcome. 
    What I'm wondering is it doable  to set up  studio for one user and 
regular ubunto 8.04 for the other and then inter react one with the 
other to do video and sound to build movie's or video.
    I will likely not change my set up right now if it is a doable thing 
as right at the moment trying to do a video and learn Linux command line 
are about all I can stand. 
    Another questio is are their some good cheat sheets for comands that 
might be opend from the desk top?   What I have looked at are in 
alphabetical order which seems to me kind of useless if you don't know 
what command you are looking for.
                                                                         
Thanks anyone,
