3.2 Set Default Tile Resolution for a Display Surface
The information in this section supplements the information in the HP SVA System Administration
Guide on the contents of the Site Configuration File that impact Display Surfaces.
Prior to Patch Kit 2, you could specify the resolution (pixel height and width) for a tile (a
sub-element of a display block) in several ways, in order of precedence:
1. Using a job-specific tile resolution by specifying the -g resolution or --tile-geometry
resolution options to all of the SVA job launch scripts, such as sva_chromium_dmx.sh.
2. Setting the SVA_TILE_GEOMETRY variable in the SVA_JOB section in their User Configuration
File (~/sva_cluster-name.conf).
3. Relying on the SVA_TILE_GEOMETRY tag value in the SVA_JOB section of the Site
Configuration File.
Patch Kit 2 provides a way to set a default tile resolution for each Display Surface. This default
resolution appears in the individual Display Surface declaration section of the Site Configuration
File. It takes the form:
SVA_TILE_GEOMETRY="1280x1024"
As a result, the tile resolution as of Patch Kit 2 is determined, in order of precedence, as follows:
1. Using a job-specific tile resolution by specifying the -g resolution or --tile-geometry
resolution options to all of the SVA job launch scripts, such as sva_chromium_dmx.sh.
2. Setting the SVA_TILE_GEOMETRY variable in the SVA_JOB section in their User Configuration
File (~/sva_cluster-name.conf).
3. Relying on the default resolution for the Display Surface as specified by the
SVA_TILE_GEOMETRY variable in the individual Display Surface declaration section of the
Site Configuration File.
4. Relying on the SVA_TILE_GEOMETRY tag value in the SVA_CLUSTER section of the Site
Configuration File.
Note that as of Patch Kit 2, the SVA_TILE_GEOMETRY tag moves to the SVA_CLUSTER
section of the Site Configuration File rather than the SVA_JOB section.
3.2.1 Use the Display Surface Configuration Tool to Set Default Resolution
You use the Display Surface Configuration Tool to set the default resolution for a Display Surface.
This requires root privileges. The tool presents you with a list of resolution options, which are
derived from information in the SVA_CLUSTER section of the Site Configuration File, specifically,
the SVA_SUPPORTED_RESOLUTIONS tag for mono displays and
SVA_SUPPORTED_STEREO_RESOLUTIONS for stereo displays.
The following example shows a sample prompt sequence from the Display Surface Configuration
tool. The italics text represents what is new in the Display Surface Configuration Tool for Patch
Kit 2:
Please enter what you would like to do:
1. List Display Surfaces
2. Create a Display Surface
3. Delete a Display Surface
4. Change the arrangement of nodes in a Display Surface
5. Replace nodes in a Display Surface with different nodes
6. Completely redefine a Display Surface
7. Replace one display node with another in one or more Display Surfaces
8. Exit
