multi-screen support
The list of supported multi-display configurations is rather large, and it
changes whenever a new graphics device is introduced. Thus, if you are
considering a Single Logical Screen or any other multi-display
configuration, we recommend consulting your HP Sales Representative
and inquiring whether the configuration you have in mind is indeed
supported.
There are general guidelines, however. For example:
•
Multi-display configurations may be limited by available power.
Depending on the capacity of your computer’s power supply, and the
power demands of the combination of graphics cards you are
considering, there may or may not be enough power to operate them
all.
•
Single Logical Screen configurations must use identical graphics
devices (see the next section).
single logical screen (SLS)
SLS is a mechanism for treating homogeneous multi-display
configurations as a single “logical” screen. This allows the
moving/spanning of windows across multiple physical monitors. The
word “homogeneous” is included because SLS only works if the graphics
devices included in the SLS Configuration are of the same type.
SLS is enabled by using SAM (the System Administration Manager tool,
/usr/sbin/sam
). To enable an SLS configuration, start SAM, and
follow the instructions below:
1. Double-click on the “X Server Configuration” button. A window
entitled “Graphics” appears, containing an icon for every graphics device
on your system.
2. Select the devices you want to combine into an SLS (click the mouse on
the first device, and [Ctrl]-click on the others). At this point, all the
devices you want to combine into an SLS configuration should be
highlighted.
3.From the “Actions” menu, choose the menu item “Modify Multi-Screen
Layout”. A dialog box appears, allowing you to specify exactly how you
want your SLS configuration to be.
