I figure I finally found out the solution to this.My initial problem was
that when I connect my laptop to a project, the projector output eats up
quiet a bit left portion of my display( my Compaq nx7010 has wide
screen display). All I had to do is after connecting the projector cable
to my laptop is restart X. Not by logging out and logging back in but by
"Ctrl" + "BackSpace" key. That was quiet easy :). The display then only
remains on the projector and I wont get it on my laptop screen this was
fine with me.The Fn + display key was not working for switching between
projector and laptop screen. There was one more problem,the resolution
on the projector screen. Everything looked as if it was stretched from
top. This I solved by replacing the following lines in my
/etc/X11/xorg.conf file.
$sudo vi /etc/X11/xorg.conf
changed
Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
Modeline "1280x800 at 60" 83.91 1280 1312 1624 1656 800 816
824 841
EndSection
to
Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
# Modeline "1280x800 at 60" 83.91 1280 1312 1624 1656 800 816
824 841
EndSection
and
Section "Screen"
Identifier "Default Screen"
Device "ATI Technologies, Inc. Radeon Mobility 9000 M9
(R250 Lf)"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 1

Depth 16
Modes "1280x800"
EndSubSection
SubSection "Display"
Depth 24
Modes "1280x800"
EndSubSection
EndSection
to
Section "Screen"
Identifier "Default Screen"
Device "ATI Technologies, Inc. Radeon Mobility 9000 M9
(R250 Lf)"
Monitor "Generic Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1024x768" "800x600"
EndSubSection
EndSection
After this save the file,restart X and voila every thing is crystal
clear on the projector output.
