hot-
keys and the configuration of the projection channels are defined in the configuration file:
/etc/MMTconfig/MMTConfigSections
This procedure must be carried out as described in section
.
The file
MMTConfigSections
consists of four sections: geometry, video, channels and rctrl.
geometry
This section starts with the keyword
geometry
and defines the geometry of the rendering machines, if in a
distributed system multiple-logical-screens are used. This geometry section must not be changed manually, but it
is configured by means of the X.11 configuration script
EOSconfig
, please refer to section
distributed system with multiple logical screens
. General information about multiple-logical-screens can be found in
section
With multiple-logical-screens an individual color depth and visual class can be assigned to each screen. Multiple-
logical-screens can be used in two different modes: Separate-screens or Contiguous-screens. These modes differ
only in the behavior of the cursor and in the demands of the arrangement of projection cubes.
The contiguous-screens mode is used if multiple screens shall be displayed on one display wall. The screens must
completely fill the rectangular array of the display wall. The cursor can be moved continuously over all screens
on the whole display wall. In the geometry section the keyword
ContiguousScreens
must be written in a
line. The following lines contain each a rendering-machine (
engine-x
), the module arrangement (
m×n
), the
position within the display wall (
X Y
) and optional the color depth (
bpp xx
) and visual class (
cc x
). The visual
class may have the values
3
(pseudo color),
4
(true color) or
5
(direct color). Please see section
for the possible color settings. All screens where not explicitly color depth and visual class is
assigned use the settings of the X server configuration.
