Blank xorg.conf

I usually connect the projector before booting. That way when X starts it detects the projector and makes the appropriate settings. Also, connecting the projector then logging out of your graphical desktop (e.g. Gnome) and back in again normally works. I recommend either of these two methods as a starting point.

In Karmic Koala (9.10), X auto-configures itself, so there is no xorg.conf by default. If you wish, you can manually create an xorg.conf file. This is sometimes problematic unless you know the exact settings that you need. I recommend that you look through the forums for a sample xorg.conf. Here is one example of a person that was trying to create an xorg.conf and resulted in failure: http://ubuntuforums.org/showthread.php?p=8272640#post8272640 , so the more specific your search, the better.

This includes configuration examples (Dualhead and Resolution):
https://wiki.ubuntu.com/X/Config
To create one the cmd is:
Xorg -configure

Try the following:

- Connect the projector and run in a terminal

$ xrandr

it should display all the detected displays and supported resolutions. To enable a particular output:

$ xrandr --output <name of output> --auto

--j

Dear Randall,
I have tried booting i with projector on, though my laptop resolution changes, there is no display on monitor.
I have also tried to change xorg settings once and burnt my fingers in a similar fashion and formatted and reloaded my OS.

I am again bit skeptical of changing my Xorg config for the reasons above unless i have very specific guidelines,
This is the output for Xorg -configure( i feel this will become okay if i reboot)
Fatal server error:
Server is already active for display 0
 If this server is no longer running, remove /tmp/.X0-lock
 and start again.

Please consult the The X.Org Foundation support
  at http://wiki.x.org
 for help.
Juan I have tried this before but with no result.

Thanks for all your help.
Could it be finally an Hardware problem? how to go about this

Ok, some research brought up, it could be a sync issue and it may work when Compiz is deactivated.
## under Jaunty desktop effects were locked for this chip GM965
## xorg.conf uses option "AccelMethod" "UXA" in device section for Intel chips
Otherwise, in Compiz config settings manager - general options -> display settings is an option called:
sync with VBlank, also resolutions can be added there.
https://wiki.ubuntu.com/X/Troubleshooting/IntelPerformance

Also gstreamer-properties has an option in Video tab: output X Window System (no Xv).
I guess you need to experiment with settings.
In basic you can take a look at log files, such as Xorg.0.log.

Maybe also take a look at x2x:
aptitude show x2x

This is what I get on typing compiz in terminal( I could not find compiz through GUI):
Checking for Xgl: not present.
xset q doesn't reveal the location of the log file. Using fallback /var/log/Xorg.0.log

Shall I remove compiz and then try? , is it safe?
No luck with x2x.
I saw the above link: https://wiki.ubuntu.com/X/Troubleshooting/IntelPerformance
Did not get anything which might be of use, tried to though I tried ti install X retro with no luck.

No need to remove compiz, only try to set visual effects to none.
System preferences -> appearance
Then,
logout/in.
