I did not test it on a release prior to 14.04. However, the following resources suggest this bug has existed since at least release 10.04:

Title:
  [Toshiba Portégé R600-10Q] VGA output doesn't work with Intel GM45
  chipset

Status in “xorg” package in Ubuntu:
  Incomplete

Bug description:
  I have just installed Ubuntu 14.04 64-bit on my Toshiba Portege
  R600-10Q laptop (a model from 2009). I am now trying to display the
  desktop on a BenQ Senseye3 22" monitor, via the vga output, but it's
  not working - the monitor says "No Signal Detected!".

  What I've done:
  I have gone into "Screen Display", where I can see the monitor is detected by the laptop.
  The monitor has a 1920 x 1080 native resolution, which I have tried to use, but I have also set it to lower resolutions, e.g. 1024 x 576.
  I have tried to use the monitor in dual screen, mirrored and single screen mode - none work.
  I have tried pressing Fn + F5 to get single screen output - the laptop screen goes blank, but still no output on the monitor.
  I have tried several monitors (of the same type, and also of a different make), so I don't think it's that.

  If I plug the vga cable in after boot up, then the monitor receives no
  signal.

  WORKAROUND: If, and only if, the monitor was plugged in to the PC's
  VGA output during boot up, then the display outputs to the monitor
  correctly.

  The laptop has the Intel® GS45 Express chipset for graphics acceleration. I installed mesa-utils and ran glxinfo in a terminal. Amongst the output was:
  OpenGL renderer string: Mesa DRI Mobile Intel® GM45 Express Chipset

  Also, in the "About This Computer" window I see:
  Graphics: Mobile Intel® GM45 Express Chipset

  I wonder if the problem is that my chipset is GS45 not GM45.

  The output of "sudo lshw -C video" is:
