I am new to Ubuntu. I am trying to connect an external monitor to my laptop.

I have looked at many forums and the solutions do not work for me or are not simple enough for me to follow.

When I try to add another monitor by choosing System > Preferences > Monitors I only see one pink monitor screen labelled as "unknown".

Some websites suggested loading nvidia driver. I have tried the command nvidia-settings and now when I try System > Preferences > Monitors I get an alert that says "It appears that your graphics driver does not support the necessary extensions to this tool. Do you want to use your graphics driver vendor's tool instead?

Clicking Yes goes to a window labelled NVIDIA X Server settings and an alert says "You do not appear to be using the Nvidia X driver. Please edit your X configuration file (just run nvidia-xconfig as root and restart the X server.

Clicking No goes to the Monitor Preferences window displaying the pink unknown monitor.

All help appreciated (nothing would be too basic for me!) Mel

Do you have a nvidia graphics card? Then you can try running the following command from the console

sudo nvidia-xconfig

Then restart. Then you may configure dual monitors from "NVIDIA X Server settings".

Hope this helps.
