in case you are interested: I've got a T30 with 1400x1050 on the LCD,
and 800x600 on the external (1024x768 works as well, it's just that some
projectors don't grok that). Also, I've got a simple perl script for
starting VNC on the external display (and starting other programs there
as well).
attached are
* XF86Config
* beamer
* ~/.vnc/xstartup
the last one could make use of a proper window manager I guess...haven't
had time to add that one yet. works nicely: presentation on the external
port (projector) @ 800x600, LCD at 1400x1050, external visible in VNC
window on LCD...very useful 8=)
cheers,
dirk
