Hi guys:

I have debian lenny 2.6.24 and xfce4 on my laptop(DELL D630) and I'm trying
to connecting the projector to my laptop, but it didn't work.
The video card on my laptop is:
01:00.0 VGA compatible controller [0300]: nVidia Corporation Quadro NVS 135M
[10de:042b] (rev a1)

When I connected the projector, I pressed Fn+F8 just same as I do on
Windows, but nothing happened.

It seems that it could not detect the projector (or monitor, I also tried to
connecting to a separate monitor), the output of the command is always as
below (I put it at the end of this post to save space here):

I just wonder if anyone has the experience on this? How can I get this to
work?
Do I need to install any additional drivers or sth?  I also appended my
xorg.conf for your check.
Thanks so much!
