I just installed Ubuntu 10.04 on my LG R590 laptop, and when I boot it, I can't get my external monitor to work. System->Preferences->Monitors won't recognize it (even when I click Detect monitors), and when I press Fn+F7 - which is my laptop's function key for switching between built-in/external displays - it does nothing.

I found in the internet this article, which says I need to edit my xorg.conf file for this to work, and says that file should be created automatically when I install Ubuntu. However, I can't find it in my /etc/X11/, and this answer says that Ubuntu doesn't need that file anymore so it doesn't create it - though it still uses it if it finds one. It also says that if I have an NVidia card (which I have) I can force Ubuntu to create it by using sudo nvidia-xconfig, but I get a command not found when I try it.

So, is there any other way to make Ubuntu recognize my external screen? Or any way to force Ubuntu to create a xorg.conf file so I can edit it according to that tutorial?

BTW, I don't know if it matters, but I connect my external monitor via HDMI-DVI cable(HDMI side goes in my laptop, DVI side goes the monitor)

OK, I managed to solve this all by myself(with some help from the Internet... and a friend who knows some Linux...)

I just had to download and install the NVidia driver, reboot, and than System->Preferences->Monitors will open the NVidia's control panel instead of the default Ubuntu one, and allow me to set everything I need plus it made me an xorg.conf file.

Now the only problem left is how to make it work in terminal mode...
