UnixWare 7 supports a large number of video adapters including those supported under SCO UnixWare 2.X and SCO OpenServer Release 5. In addition, UnixWare 7 provides the vesa X server driver. This generic driver can operate any new video card that honors the VESA BIOS interface, and is useful in supplying high resolution support to video cards that do not have a specific accelerated driver. For more information on this feature, including performance implications, see SCOhelp on your installed UnixWare 7 system.
Most video adapters are automatically configured when you install your UnixWare 7 system. However, you should record your video configuration from your previous operating system in case:
On your SCO UnixWare 2.X system, view or print the file /usr/X/defaults/Xwinconfig. This file contains keyboard, video adapter, and monitor definitions. The important lines are shown here:
chipset = GD54xx # video chipset
model = "GD54xx" # the core drawing lib for this class
vendor_lib = gd54xx_256.so.2 # chip specific drawing lib
virtual_size = 1024x768 # actual Frame Buffer size
vendor = "Cirrus Logic - Generic" # vendor name
From this information, you can determine that the configured video
adapter is a Cirrus Logic GD54xx series model configured for 1024x768
mode.
Record this information, then (if auto-detection or auto-configuration fails) use it to configure your adapter on UnixWare 7 using the SCOadmin Video Configuration Manager.
To obtain information about the currently configured adapter, run the Video Configuration Manager.
The display at the top of the screen lists the name of the adapter, any configured monitor, and the resolution.
Record this information, then (if auto-detection or auto-configuration fails) use it to configure your adapter on UnixWare 7 using the SCOadmin Video Configuration Manager.
If you install your UnixWare 7 system and find that your video adapter is incorrectly configured, or you want to modify configuration, try the following.
To run your system in a safe video mode
Enter /usr/bin/X11/setvideomode -stdvga. This This sets IBM VGA 640x480-16 mode, which is almost always safe for any adapter.
To restore the adapter's default configuration
Enter /usr/bin/X11/setvideomode -default.
Do this if initial auto-configuration worked well enough to
get the video working, but you manually configured the adapter
to a different setting and lost the use of the video adapter.
This -default option restores the settings to initial auto-configuration defaults.
To determine the video adapter in the system
Enter /usr/bin/X11/VideoHelp.
This command lets you know what video adapter is present on your system.
