Thanks very much for the reply Alex. Removing gconf did'nt help
unfortunately. I will research on gconf. But I have ONE last question.
I realized that if I force the display to external monitor by default,
I can use the function key to  switch back to the laptop screen if
needed. So my LAST question is how do configure my xorg.conf that uses
radeon to default to external display ?

I found this link that mentioned defaulting external display but since
it uses fglrx, I think  "Generic Autodetecting Monitor" option didn't
work for me -

I also tried -
Section "Monitor"
           Identifier      "LVDSMonitor"
           Option          "Disable"    "TRUE"
EndSection

The result was
......
(II) RADEON(0): Output VGA-0 disabled by config file
(II) RADEON(0): Output LVDS disconnected
(II) RADEON(0): Output S-video disconnected
(EE) RADEON(0): No valid modes.
(II) UnloadModule: "ati"
(II) UnloadModule: "int10"
(II) Unloading /usr/lib/xorg/modules//libint10.so
(II) UnloadModule: "vgahw"
(II) Unloading /usr/lib/xorg/modules//libvgahw.so
(II) UnloadModule: "radeon"
(EE) Screen(s) found, but none have a usable configuration.
