To run emgdgui, you need to ensure that the X server has been configured to use Intel® EMGD. See Configuration Overview for details on configuring and installing the Intel® EMGD.
You need GTK+ and libglade, which are part of the Linux* distribution and should already be installed.
Note: It is not necessary to manually install the emgdgui, the install.sh has included the installation. The emgdgui is installed to the system and you can execute it by typing emgdgui in xterm or find the “EMGD GUI Utility” in System Tools.
Using the emgdgui Runtime Configuration Utility
The emgdgui application provides four tabs: Driver Info, Display Config, Display Attributes, and Color Correction.
• Driver Info: Contains the driver information.
• Display Config: Contains current display information and allows configuration of display configurations, display resolutions for primary and secondary displays and enabling/disabling of a specified port.
• Display Attributes: Contains the supported Port Driver (PD) attributes and allows configuration of PD attributes.
• Color Correction: Contains current color-correction information for the framebuffer and overlay. Using this tab, you can change the framebuffer and overlay color settings.
The figure below shows the Driver info tab.

The Display Status section of the above dialog shows the current configuration for the Primary and Secondary displays.
In the Display Configuration section of the dialog, select the required display configuration in the Display Config drop-down list. This allows the user to choose between Single, Clone, and Extended for all connected ports. A maximum of two ports per display configuration is currently allowed.
In the Primary Mode and Secondary Mode sections of the dialog, you can change display resolutions via the Resolution drop-down list.
In the Display Settings section of the dialog you can view and change the settings for a port and then rotate and flip the display via the appropriate drop-down lists:
• Port: Allows you to select the required port.
• Port Status: Allows you to enable or disable the selected port.
Note: For Chrontel 7306, there is an additional Refresh button not shown in the screen shot above. If you change the output type between HDMI and VGA during runtime, click this button to reset the display output to the new display port.
To view or change the attributes for a port, click the Display Attributes tab. The figure below shows a sample configuration. Please see Port Driver Attributes for detailed information on port driver attributes.
