[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
