[Bug 892589] Re: attaching an external monitor to a laptop makes the image bad

 

I read the information on https://wiki.ubuntu.com/Bugs/FindRightPackage
and took a package that could be involved in this issue. One thing to
note: If you start Ubuntu with the external monitor everything goes
really fine. This bug happens when you attach the monitor while Ubuntu
is running.

** Package changed: ubuntu => metacity (Ubuntu)

Title:
  attaching an external monitor to a laptop makes the image bad

Status in “metacity” package in Ubuntu:
  New

Bug description:
  If you attach an external monitor to a laptop while Ubuntu is running,
  always makes the image of the screen look bad on both the internal and
  the external monitor. I have two command attached to keyboard
  shortcuts which sometimes can make the computer usable again, if you
  switch back and forth between the internal and external monitor with:

  xrandr --output LVDS1 --off --output VGA1 --auto #switch on the internal monitor, external off
  xrandr --output LVDS1 --auto --output VGA1 --off #external on, internal off

  The success seem to depend on what programs are running at the moment
  of running those commands. If you only have a terminal opened it goes
  fine, but with Libreoffice and Firefox you need to restart Ubuntu.

  Attached are three screenshots which all show the screen looks like
  when the external monitor is attached.

  Ubuntu 11.04
