Unable to view screen


I am running Xubuntu 12.10 on a HP dv2000 laptop with no external monitor connected. I went into the display settings and unchecked use this monitor or something like that. As soon as I did that my screen went black. I'm assuming that it things that there is a second monitor and now the "second monitor" is the main display? How can I get my main screen back? Do I have to go into a config file to do this? I'm lost. Can't do anything without a screen.

I can get a command line by going into tty1

Thanks!!!

just a casual thought, can you plug your lappy to TV by dvi/video out?

Does the laptop have a fun key to switch between internal & external monitor? Did you disable the output, or the video device?

I think I disabled the output. I'd like to solve this problem without having to connect an external monitor to the laptop. Could I just trash the config file, and reboot? Would that create a new config file defaulting to the laptop's screen? If so, what file do I trash, or if that is not feasable, what file do I have to edit to get me back up and running?

Can you ssh into it to edit the file?

According to a site I found using Google, the file is ~/.config/monitors.
Make a backup of the file, and try editing it.

Your could try using xrandr.
Here is a blog site giving an example: http://pihalf.wordpress.com/2009/11/...e-with-xrandr/

Here is an example Editting the xorg config file: http://www.bingshui.org/tech/definin...xubuntu-12-04/

Oddly one of my desktop monitors just went out. (Or the dvi output of graphics card).

You should have the Fn-key to swap screen output between external VGA and laptop display working. It's rare that this key handling is not enabled and functioning. But this is only true when you are logged in, so sometimes one has to login "blindly", wait a moment, then hold down the <Fn> key and press the key to toggle between output screens. On an EeePc it is Fn+F8.

Talking about EeePC:s - On these laptops, when having dual boot Win+Lin the energy saver stuff sometimes get things wrong, especially when changing screen outputs, and dims the LCD display right down to totally black. Can be quite confusing in combination with not knowing if the video gets out on a VGA port, HDMI or the internal LCD. Puts a smile on your face when you press the Fn+F6 a couple of times and your video output shines up on the LCD, just as you wanted.
