Dual screens in Ubuntu

[Rixwel]

I have problems to get dual monitors to work in the latest Ubuntu. When I had Vista Home Premium on my computer, found the external screen, an HP w19b without problems. But when I plug in via a VGA touch screen does not react for Ubuntu. The screen is nothing wrong with because I have tested it on another computer. The computer I have is HP Pavilion DV9575eo.

I am an inexperienced Linux users, and why I switched from Vista is because I was tired of it. And according to HP's support can not install XP on it but to slip stream a disc, whatever that means.

How can I do to make Ubuntu to detect the screen? I would not let the screen stand and gather dust on the desktop.

Dual screens.

If you check your config, see if theres a nVidia card in it? You must install a small program called nvidia-settings. Add / Remove or synaptic or terminal, what you feel.

Turn the card. Connect the screen.

Begin

Alt-F2 > nvidia-settings

Now, the screen visible through the "X-server display configuration".

Ok, thanks. But I manage to not get the external screen to become secondary. I want to use the portable computer screen that primary.

Untested, but it should work

Click the Configure > select Twin View

Close all programs.

Ctrl-Alt-Delete so you logged out and X restarts.

When everything started on, I was forced to change the setting again.

And now the picture has been divided up. When I open Firefox ports half the window on the external screen and the other half on the portable computer screen.

Aha, it was so

Click the Configure again and select separate screens > Ctrl-Alt-Delete.

Should look a bit on how to do it right ...

When I select separate screens, it selects the portable computer screen.

When I select separate screens, it selects the portable computer screen.

OK, no laptop to test with. Check out this article - Ubuntu, NVIDIA and Two Monitors

Start the terminal -> select nvidia-settings

You have to have admin powers, it seems.

You see two screens as shown in the article?

[Rixwel]

Yes, it looks like the picture.

But as it stated in the article that you can not move around the window between the screens if you have separate screens, so did setting on Twin View. It works well anyway.

Thanks for your help!
