I am trying to connect my Macbook Pro to external Samsung VGA monitor via mini display port to VGA adapter. But the monitor is not being detected.

  1. It is working fine with OS X
  2. It is not detected in Kubuntu only.
  3. It works with a coupled mini-display to HDMI and HDMI to VGA.
  4. If I unplug the VGA cable from the monitor side, a monitor is detected named DP1. (thats true! the VGA cable with a loose end, with no monitors connected, it gets detected. )

I tried upgrading from Kubuntu 14.04 to 14.10. Still the same.

Product Details:

Moelissa Mini Display Port To Vga Adapter  
SUPC: SDL956438123

Whether it's plugged in or not, the output of lsusb is the same.

I just downloaded the latest kernel Release Candidate and did a grep --recursive --ignore-case Moelissa and the results are: zilch, nada, nothing, rien du tout, nichts, nikske, ничего, नथिंग!

So you basically have 3 options (higher number is more difficult):

  1. Do nothing and wait until Linus Torvalds gets to your problem.
  2. Buy one that has Linux support
  3. Get involved in Linux kernel development and develop a driver yourself
