Did you try using xrandr?

Hi,

first you should update to RHEL 5.4 using yum. There are dozens on fixes since RHEL 5.2. After that check again if your problem exists and come back with some feedback.

Hi,

sorry, but i cannot upgrade to 5.4, we freeze the image on 5.2.
if i boot the laptop and press Fn+F7 then i can see the output on both screens, but i would like to switch between them without reboot the machine and connect the projector while booting.

here is the xrandr output:

What is the output of the command with the external monitor plugged in?
xrandr -q

Hi,

Thanks for the reply, i think i got it right, i change xorg.conf see below,

and now i am booting the lp without the projector, when it is up connect the projector, but i need to log out and log in again so the x will be refreshed, then i can see both on lcd and on the projector, so i think it is ok now.

Thanks
E
