Hi everybody!

That might be a good idea if I had a cd-rom in the box but unfortunately I
don't!

That one is actually working. I had to add this to "xorg.conf"

	Section "Device"
	        ...
	        Option          "NoDDC" "1"
	EndSection

This way Ubuntu wouldn't search for the screen. Now I only have to detect
whether a screen is present or not and start the 2nd patch with "-gui" or
"-nogui" . I think

[dmesg]
     |
 [shell]

should somehow work for that.

That won't change the fact that Ubuntu won't start up. Changing the command
line to start the Pd patch is already good enough for that.


Thank you all for your suggestions. I think Cyrille's way is the best way to
go with my setup.
