Hi,

It is only a matter of adjusting permissions and / or enabling the root power through /etc/sudoers

Mike

I didn't see a UseDisplayDevice option on your config. On your dual head card, do you have 2 DVIs or a DVI and a VGA? If you have the latter, I'm guessing the LCD is on the DVI. Correct me if I'm wrong.

You would need to add this option to your screen or display section:



If you have the LCD on the VGA then the option is




If you have two DVIs I think it's ... "DFP-0" for the first head or something like that.

More info on: ftp://download.nvidia.com/XFree86/Linux ... dix-d.html

As for running the code as root, that's what the sudo command is for.




should give your script aliasing or copy/delete privileges of the root.

Hey Guys thanks for the help. I have the 2 scripts working no problem, I just need to figure out how to make the LCD (VGA) show video when the projector (DVI) is plugged in. The only way I can make it work is to unplug the projector and reboot. Any ideas?
JJ

edit: Upon closer inspection my 2 xorg.conf files are identical. Why when the projector is plugged in, there is no video on the LCD. Must be an issue of the resolution chosen by myth. I notice they are different.

Did you add this line to your LCD xorg file?


It goes under

I did add:

to both the monitor and the screen section with no effect.

Thanks for the input, I am completely lost on this problem these days.

The first thing I'd test is boot with the projector unplugged. It should go to the monitor. Now plug the projector in and try the projector script. Make sure that works.

If that works, double check that your script is actually copying/linking the right file into the xorg.config file. You can double check this by running the monitor script and then using nano to look at xorg.config and looking for the new option.

If that checks out, your monitor must not be announcing itself when X starts.

In that case, you should also use



Which will force detection of the VGA attached device.

I have done this. After some work I know both the scripts work. I added a line at the beginning of each xorg.conf file so I could identify them.

I tried adding
but after either
or a reboot there is no video on the lcd, the screen just turns blue. The only way I can get video on the lcd is to reboot with the projector unplugged.

Thanks for the input. I would be pretty happy to defeat this issue.

I see the problem now. You have an ATI card and I was using Nvidia options.

Delete the other two option lines I wanted you to put in and use this one instead:


I think that line goes in

It might not work because the page says



If that doesn't work you might be able to set up cloning so both monitors display the same thing but it looks scary:
