Resolution and Color Depth
The resolution and color depth can be chosen directly from two lists in the middle of
the dialog. The resolution you select here marks the highest resolution to use. All
common resolutions down to 640x480 are also added to the configuration automatically.
Depending on the graphical desktop used, you can switch to any of these later without
the need for reconfiguration.
Dual Head
If you have a graphics card with two outputs installed in your computer, you can connect
two screens to your system. Two screens that are attached to the same graphics card
are referred to as dual head. SaX2 automatically detects multiple display devices in the
system and prepares the configuration accordingly. To use the dual head mode of a
graphics card, check Activate Dual Head Mode at the bottom of the dialog and click
Configure to set the dual head options and the arrangement of the screens in the dual
head dialog.
The tabs in the row at the top of the dialog each correspond to a graphics card in your
system. Select the card to configure and set its multihead options in the dialog below.
In the upper part of the multihead dialog, click Change to configure the additional
screen. The possible options are the same as for the first screen. Choose the resolution
to use for this screen from the list. Select one of three possible multihead modes.
Cloned Multihead
In this mode, all monitors display the same contents. The mouse is only visible on
the main screen.
Xinerama Multihead
All screens combine to form a single large screen. Program windows can be posi-
tioned freely on all screens or scaled to a size that fills more than one monitor.
NOTE
Linux currently does not offer 3D support for Xinerama multihead environ-
ments. In this case, SaX2 deactivates the 3D support.
The arrangement of the dual head environment describes the sequence of the individual
screens. By default, SaX2 configures a standard layout that follows the sequence of the
