Configuring video adapters

Adding and modifying video configurations

Use the Video Configuration Manager to add new video adapters and monitors to the system and to modify the existing video configuration.

You can start the Video Configuration Manager in any of these ways:

Open the Desktop's System Administration window (double-click on the System Administration icon) and double-click on the Video Configuration Manager.
Start the SCOadmin launcher by entering scoadmin on the command line, then select the Video Configuration Manager.
Enter scoadmin video on the command line.

NOTE: While any user can view the system's video configuration, only root can modify video configuration.

If this task is performed in multiuser mode, users currently logged in and running the X server will not see any changes until their next session.

To add or modify your video configuration:

Start the Video Configuration Manager in one of the ways described above.
The X.org xorgcfg tool is launched within the Video Configuration Manager. This tool probes your video hardware and creates an initial X11 server configuration file, /etc/xorg.conf. Select OK to continue.
If you are adding a new video adapter, or if the configuration that was set at installation-time isn't working well, select Configure card from the xorgcfg Main menu.
Follow the prompts to configure settings for your video adapter. You can choose from a database of video adapter definitions, which includes information about the card's chipset and the video driver to use. See ``Supported video adapters'' for the video drivers that are provided in SCO OpenServer Release 6.0.0.
When you are finished, select OK to return to the Main menu.
Select Configure monitor to refine the settings for your monitor. Follow the on-screen prompts to define the supported frequencies for your monitor. You are asked to provide both the horizontal sync range and the vertical sync range.
NOTE: Do not change these monitor values without first consulting your monitor's documentation for supported settings. Incorrect values can cause problems ranging from out-of-sync errors to severe monitor damage.

When you are finished, select OK to return to the Main menu.
Select Configure screen to refine the resolution at which your configuration will run. Follow the prompts to set the appropriate color depth and video mode (or resolution) to run at for the given color depth. Only VESA standard modes, as determined by your video hardware, are supported.
When you are finished, select OK to return to the Main menu.
Select Write xorg.conf and quit. Your new configuration settings are written to the /etc/xorg.conf file and the Video Configuration Manager exits.
Run the following commands to restart the X server and activate your new video configuration:

scologin stop
scologin start

NOTE: If you experience problems with your X configuration after running the Video Configuration Manager, you may need to make manual modifications to the configuration. See ``Configuring video adapters manually'' for information of performing a manual configuration.

If, after performing Steps 1 and 2 in that procedure, you still experience problems, you will need to make your own modifications to the /etc/xorg.conf file. See the xorg.conf(4) manual page for details.
