I am using Ubuntu 13.10 on a macbook pro. Would like to install external monitor VGA with the mini-port. no success.

  • Trying: Settings→displays - nothing recognised.
  • Trying xrandr --auto - nothing
  • There is no xorg.conf on my Ubuntu.

In use 2 graphic drivers:

VGA compatible controller Intel Corporation 3rd Gen Core
VGA compatible controller NVIDIA Corporation GK107M

and, OpenGL vendor string: nouveau

What should I do to activate the external monitor (need for beamer presentations)?

Reinstall the driver:

sudo apt-get --purge autoremove xserver-xorg-video-nouveau && sudo apt-get install xserver-xorg-video-nouveau

If the problem still exists, run :

sudo dpkg-reconfigure -phigh xserver-xorg
