I have installed ubuntu onto an Acer Aspire One netbook that has no other operating system. (The hard drive had been totally formatted). When I power on the computer, a black screen appears. But, if I attach an external monitor and use Fn + F5 (twice), my netbook screen then works. Does anyone have any idea how I can get my netbook screen to work without having to go through this dual monitor routine? Thanks.

I'm not an Ubuntu expert, I stick mainly with CentOS or Fedora. But can try to help.
What version of Ubuntu is it?
So when you boot without the external monitor, are you seeing the grub menu?
Assuming you are seeing the grub screen can you tell if it is grub or grub2? It should say on the screen. My guess if a new Ubuntu its grub2.

Now this isn't a fix, but its where I would first start myself.

Keep the external monitor unplugged.

When booting, press a key to stop grub from automatically bringing up the OS. Hopefully you haven't done something like set the timeout to 0. :>

Now here's where my suggestion may not exactly work, as it will differ between grub classic and grub2. Add " single " to the kernel line, make sure you pick your default kernel(normally would be the newest/highest version)

This should get you into single user mode. In most all Linux distros I have played with, not matter what your monitor setup is, they play nicely with them in single user mode.

Hopefully here you got a login prompt and you can log in. Well I'll stop here, as I don't know if you get this far. But at this point you can start playing around with things.

Thanks for your suggestions. How do I get to the point where I can change my kernel line?
As far as I can tell, I have Ubuntu 13.04 and GNU GBUB Version 2.0-13ubuntu3.

As you suggested, with no external monitor connected, I powered up and got grub to stop before loading the OS. (I held the "Shift" + e keys). My netbook then showed a screen with 4 choices (Ubuntu, Advanced options for Ubuntu, and two memory tests.)

Do I get to the kernel line from here? Thanks again.
