[Guilhermino <guilherminocorreia@xxxxxxxxx>]

I've both taken a picture and shot a small video that I think shows it better. In the photo the window is blurry because I was moving it with the mouse ( when the problem mainly manifests ), but you can see the scan lines by the side even if not so many as what I actually see due to exposure time.
I've also now noticed that a solid background color shows a vertical moving fluctuation not too contrasted, as in a noisy signal connection.

Title:
  radeon driver on lubuntu 14.04-15.10 displays white flickering scan
  lines and occasional parts of the windows on external monitor

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  On a Compaq Presario 2500 laptop with an Ati IGP 345M graphics card,
  when connected to an external monitor ( SAMSUNG P2470HD - FullHD
  monitor/tv ) through a VGA analog connection, and using the latest
  open radeon driver on Lubuntu 14.04.2 with all the latest updates,
  when using the native resolution ( 1920x1080@60 ) of the monitor, and
  even at lower ones, except the lowest, there are small white lines
  flickering all over the display especially when there is movement in
  the windows or menus, and sometimes even small fragments of the window
  contents appear momentarily across different parts of the monitor.
  This does not happen when using a Windows XP installation on the same
  laptop with the same monitor and with the same D-Sub cable.

  I've tried to install the fglrx driver, but there seems to be none
  available for this card either on the AMD website nor on the
  additional drivers repository of lubuntu. Installing the fglrx driver,
  the card was never recognised. The command "sudo amdconfig --initial"
  returns the error message: "amdconfig: No supported adapters
  detected".
