According to your Xrandr.txt your machine doesn't have a VGA port. It only has a built-in LCD, HDMI and/or DisplayPort.
So please explain in more detail what the problem is. Do you mean you have plugged in a monitor and it's not working? If so then please plug it in again, run 'xrandr' in a terminal while it's plugged in and send us the output: xrandr > xrandragain.txt ** Changed in: xorg (Ubuntu) Status: New => Incomplete ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1780439 Title: Dual Monitor not detect on VGA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1780439/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
