Hi
Clone mode should work out-of-box with a normal configuration.

I'm not quite sure what that means. That it should work without me changing the configuration at all? Because it doesn't. The external monitor has a bright, green screen, nothing else.

This is how far I've got:

screens.zip results in monitor having bright green screen.

screens2.zip does not work, as shown in the 4 screen shots.

Files.

I tried to use an HP flat screen with my laptop and got errors about it 'not being able to open display 1' or 'resolution not set - could not open' on top of a slew of other errors along these lines, in the end I turned to google for help ... and found a tutorial to set up a config for xrandr before trying to use the monitor. in the beginning I only had one problem: It would only let me do a max of 640X480 resolution (which made the desktop hard to navigate) but once I opened Administration->Monitors I had the 1024 option ... I've been looking for the tutorial I used but can't find it ... I will return with a link once I find it.


edit: I think I found it ... I am pretty sure this is it: http://www.zoinks.org/home/technolog...ntel-gma-x3100

If something from there doesn't come out right, I can't really help (That's why I need a tutorial in the first place haha ) but it did work for me, and hopefully can work for you to. Good luck.

So this would mean I ditch my xorg.conf and start over?

From the zoinks tutorial:

Quote:
Step 1: You need to make sure to have the right graphics drivers set up.

In System >> Administration >> Screens and Graphics
On the Tab "Graphics Card"

You should see two graphics cards make sure *both* have selected the "Intel Experimentla modesetting" drivers. (This may not actually be necessry, but that's what I did and it worked).
This step fails for me.

Okay, according to this post, it will never work for me.

http://ubuntuforums.org/showpost.php...42&postcount=7

So I've gone for a totally different solution, and made that work.
