[ltp] UI chooser for non-root switching of xorg.conf prior to starting X? - plus sample xorg.conf files for T41p...

[Chris Almond]

I would like to be able to start X with -config passed to it  from some 
kind of user friendly chooser, to switch on which xorg.conf file to use 
depending on what I'm doing at that time (for instance, switching 
between in office w/external 1280 TFT panel on second head, or in 
meeting room w/beamer attached on 2nd head, or singlehead on native 
LCD).  Currently I'm switching by setting default init level to 3, 
logging onto console as root then doing the following..

# cd /etc/X11
# ln -s /etc/X11/xorg.conf.<head_setup_I_need>  /etc/X11/xorg.conf
# init 5

Has someone built a chooser app or script that will prompt me for what 
setup I need - maybe present a list of choices - where I don't need to 
login as root first.... in fact where I can just set default run level 
to 5 and be prompted for which xorg head config I need?  I looked into 
doing this with GDM xsession choices, but I don't think this approach 
works - I don't see a way to pass X server startup parameters to 
gnome-session or startkde from the display manager.
