Dual Monitor Setup
|
|
==================
|
|
|
|
The first step in getting OpenLP working on your system is to setup your
|
|
computer properly for dual monitors. This is not very difficult, but the steps
|
|
will vary depending on operating system.
|
|
|
|
Most modern computers have the ability for dual monitors. To be certain,
|
|
check your computer's documentation. A typical desktop computer capable of dual
|
|
monitors will have two of, or a combination of the two, connectors below.
|
|
|
|
**VGA**
|

|
|
|
|
**DVI**

|
|
|
|
**HDMI**
|

|
|
|
|
**S-Video**
|
|
|
|
.. image:: pics/svideo.png
|
|
|
|
A laptop computer setup varies slightly. Generally you will need only one of
|
|
the outputs pictured above since your laptop screen serves as one of the
|
|
monitors. Some older laptops may require a key stroke generally involving the
|
|
:kbd:`Fn` key and another key (labeled on the keybaord) to enable the second
|
|
monitor.
|
|
|
|
A typical OpenLP setup consist of your normal single monitor, with your
|
|
projector hooked up to your computer as the second monitor. With the option of
|
|
extending your desktop across the second monitor, or your operating system's
|
|
equivalent.
|
|
|
|
**Special Note For Projectors Using USB Connections**
|
|
|
|
Users have reported experiencing difficulties when using a projector with a USB
|
|
connection. Third party software is often required to properly configure
|
|
dual monitors. If possible, it is best to use a direct output (VGA, DVI, HDMI,
|
|
S-Video) from your machine's video card. If a USB connection is your only option
|
|
please consult the manufacturer's manual for instructions on a proper setup.
|
|
|
|
Microsoft Windows
|
|
-----------------
|
|
|
|
Dual monitor setup is similar among all the currently supported Windows
|
|
releases (:ref:`win7monitor`, :ref:`winvistamonitor`, :ref:`winxpmonitor`), but
|
|
does vary slightly from one release to the next.
|
|
|

|
|
Windows 7
|
|
^^^^^^^^^
|
|
|
|
Windows 7 has using a projector in mind. Simply connect your projector and
|
|
press :kbd:`Windows+P`.
|
|
|
|
The more traditional way is also fairly straight forward. Go to
|
|
:guilabel:`Control Panel` and click on :guilabel:`Display`. This will open up
|
|
the :guilabel:`Display` dialog. You may also bypass this step by a right click
|
|
on a blank area on your desktop and selecting :guilabel:`Resolution`.
|
|
|
|
.. image:: pics/winsevendisplay.png
|
|
|
|
Then click on the :guilabel:`Adjust resolution` link in the left pane. Enable
|
|
your projector and make sure that the selected value for :guilabel:`Multiple
|
|
displays` is :guilabel:`Extend these displays`.
|
|
|
|

|
|
|
|
Windows Vista
|
|
^^^^^^^^^^^^^
|
|
|
|
From :guilabel:`Control Panel` click on :guilabel:`Personalize`, or right click
|
|
a blank place on the desktop and click :guilabel:`Personalization`.
|
|
|
|
.. image:: pics/vistapersonalize.png
|
|
|
|
From the :guilabel:`Personalization` window click on :guilabel:`Display
|
|
Settings`. Click on the monitor that represents your projector and make sure
|
|
you have checked :guilabel:`Extend the desktop onto this monitor`.
|
|
|
|
.. image:: pics/vistadisplaysettings.png
|
|
|
|
.. _winxpmonitor:
|
|
|
|
Windows XP
|
|
^^^^^^^^^^
|
|
|
|
From :guilabel:`Control Panel` select :guilabel:`Display`, or right click on a
|
|
blank area of the desktop and select :guilabel:`Properties`. From the
|
|
:guilabel:`Display Properties` window click on the :guilabel:`Settings` tab.
|
|
Click on the monitor that represents your projector and make sure you have
|
|
checked :guilabel:`Extend my Windows desktop onto this monitor`.

Linux
|
|
-----
|
|
|
|
Due to the vast varieties of hardware, distributions, desktops, and drivers
|
|
this is not an exhaustive guide to dual monitor setup on Linux. This guide
|
|
assumes you have properly set up any proprietary drivers if needed. You
|
|
should seek out your distributions documentation if this general guide does not
|
|
work.
|
|
|
|
**Note to Ubuntu 11.04 Users:** Ubuntu 11.04 uses the new Unity interface. It
|
|
is recommended to use the *Classic Desktop* option. OpenLP and other
|
|
applications requiring dual monitors may not work well with Unity due to issues
|
|
experienced by other users with the Unity interface.
|
|
|
|
GNOME 2
|
|
^^^^^^^
|
|
|
|
This guide is for users of the GNOME 2 desktop who do not use proprietary
|
|
drivers. From most distros go to :menuselection:`System --> Preferences -->
|
|
Display Settings (Monitors)`. Set up your projector with the correct resolution
|
|
and make sure that :guilabel:`Same image on all monitors` is **unchecked**.
|
|
|
|
.. image:: pics/gnome.png
|
|
|
|
GNOME 3
|
|
^^^^^^^
|
|
|
|
This guide is for users of the GNOME 3 or GNOME Shell desktop who do not use
|
|
proprietary drivers. In GNOME shell in the search box type *Displays* or in
|
|
GNOME shell or fall back mode go to :menuselection:`Applications --> System Tools --> System Settings`
|
|
then select Displays. Set up your projector with the correct resolution and
|
|
make sure that :guilabel:`Mirror displays` is **unchecked**
|
|
|
|
.. image:: pics/gnome3displays.png
|
|
|
|
If after setting up your monitors you have the top panel on the wrong monitor
|
|
simply drag it to the monitor you want to serve as the primary screen.
|
|
|
|
.. image:: pics/gnome3drag.png
|
|
|
|
KDE
|
|
^^^
|
|
|
|
This guide is for users of the KDE desktop who do not use proprietary drivers.
|
|
From most distros click the Kick Off menu and navigate to
|
|
:guilabel:`System Settings`
|
|
|
|
.. image:: pics/kdesystemsettings.png
|
|
|
|
Click on the display and monitor icon.
|
|
|
|
.. image:: pics/kdedisplay.png
|
|
|
|
From here you will need to set up your projector with the appropriate
|
|
resolution, and position. OpenLP works best projecting to the monitor on the
|
|
right.
|
|
|
|
Linux Systems Using nVidia Drivers
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
This guide is for users of the proprietary nVidia driver on Linux Distributions.
|
|
It is assumed that you have properly setup your drivers according to your
|
|
distribution's documentation, and you have a working ``xorg.conf`` file in
|
|
place.
|
|
|
|
If you wish to make the changes permanent in setting up your system for dual
|
|
monitors it will be necessary to modify your ``xorg.conf`` file. It is always a
|
|
good idea to make a backup of any critical file before making changes::
|
|
|
|
user@linux:~ $ sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.old
|
|
|
|
For those using systems that use the root user instead of sudo, change to root
|
|
and enter::
|
|
|
|
root@linux: # cp /etc/X11/xorg.conf /etc/X11/xorg.conf.old
|
|
|
|
The exact location of the ``xorg.conf`` file can vary so check your
|
|
distribution's documentation.
|
|
|
|
If you want to make your changes permanent run nVidia settings from the
|
|
terminal::
|
|
|
|
user@linux:~ $ sudo nvidia-settings
|
|
|
|
Or, as root::
|
|
|
|
root@linux: # nvidia-settings
|
|
|
|
If you do not want to write the changes to your ``xorg.conf`` file simply run
|
|
the nVidia Settings program (:command:`nvidia-settings`) from your desktop's
|
|
menu, usually in an administration or system menu, or from the terminal as a
|
|
normal user run::
|
|
|
|
user@linux:~ $ nvidia-settings
|
|
|
|
Once you have opened nVidia Settings, click on :guilabel:`X Server Display
|
|
Configuration`. Select the monitor you are wanting to use as your second
|
|
monitor and click :guilabel:`Configure`.
|
|
|
|
.. image:: pics/nvlinux1.png
|
|
|
|
After clicking :guilabel:`Configure`, select :guilabel:`TwinView` and click
|
|
:guilabel:`OK`.
|
|
|
|
.. image:: pics/twinview.png
|
|
|
|
Click :guilabel:`Apply` and if you are happy with the way things look click
|
|
:guilabel:`Keep` to save your new settings. Don't worry if something goes wrong,
|
|
the settings will return back to the previous settings in 15 seconds without any
|
|
action. nVidia Settings should take care of selecting your optimum resolution
|
|
etc, but that can be changed as needed. When you are happy with everything click
|
|
on :guilabel:`Save to X Configuration File`.
|
|
|
|
.. image:: pics/xorgwrite.png
|
|
|
|
Click :guilabel:`Save` and you should be set. You may want to restart X or
|
|
your machine just to make sure all the settings carry over the next time you log
|
|
in.

Linux Systems With Intel Video
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Generally systems with Intel video cards work very well. They are well supported
|
|
by open source drivers. There are, however, a couple of issues that may require
|
|
some work arounds.
|
|
|
|
**Resolution Issue**
|
|
|
|
There is a limitation with certain cards which limits the total resolution to
|
|
2048x2048, so both monitors can not have a total resolution totaling more than
|
|
that. To work around this it may be necessary to position your monitor as a top
|
|
or bottom monitor as opposed to the typical side by side setup. This can easily
|
|
be accomplished through your desktop's control of monitors. Please see the
|
|
sections on dual monitors with KDE and GNOME above.
|
|
|
|
**Primary Monitor Issues**
|
|
|
|
With certain cards your system may get confused on which is the primary display.
|
|
For example many users will be using a laptop. You will want your laptop screen
|
|
to be the primary screen, and your projector to be the secondary monitor.
|
|
Certain Intel cards reverse this. To work around this you will need to know the
|
|
name of your monitor. If you are a KDE user this info is given to you in the
|
|
display settings. If you are not using KDE enter the following in a terminal
|
|
without your projector connected to your computer::
|
|
|
|
user@linux:~ $ xrandr -q
|
|
|
|
This will give you a long string of output. Screen names will be something along
|
|
the lines of LVDM, VGA-0 or some convention similar to that. Without your
|
|
projector connected to your computer only one monitor will show as being
|
|
connected. That will be the monitor you will need to use as the primary. Now
|
|
connect your projector and enter::
|
|
|
|
user@linux:~ $ xrandr --output LVDM --primary
|
|
|
|
**Note** it has been reported that when this issue is occurring you will not
|
|
want to connect your projector until your desktop is running.
