Description

Default Display Modes

The Default Display Modes section allows you select the default resolution, color depth, and refresh rate for the configuration. If you do not select a default display mode, the package uses the default display mode for the operating system it is installed on.

Disable Hardware Acceleration

Disable or enable hardware 2D acceleration. The default is to enable hardware acceleration, so to disable acceleration, click the check box.

Enable Hardware Cursor

Enable the use of the hardware cursor. By default, the hardware cursor is disabled.

Enable Use Double Buffer

(Shadow Framebuffer)

Enable double buffering on the framebuffer. By default, double buffering is disabled. To enable it, click the check box.

No Xinerama

Xinerama support. Xinerama is an extension to the X Window System which allows applications and window managers to use the two (or more) physical displays as one large virtual display. By default, Xinerama is enabled. To disable it, click the check box.

Disable OpenGL* Installation (Disable the DRI2 Option)

OpenGL* (Disable the Direct Rendering Infrastructure (DRI) Option). DRI2 allows the client to directly write to DMA buffers that are used by the graphics hardware.

To disable OpenGL, check the box. The option “DRI2” “0” will be set for every available display. This will turn off direct rendering and disable hardware accelerated OpenGL.

By default, OpenGL is enabled. No “DRI2” line(s) are placed in the configuration file. The driver will intelligently determine if DRI2 can be supported and will enable it if possible.

Note: If you manually edit the configuration file and set option “DRI2” “1” on more than one display, deadlock will occur and OpenGL will fail. If you are unsure of which setting to use, just leave the box unchecked (i.e., cleared) and do not edit the DRI2 option in the configuration file and the driver will handle it automatically. This feature can be used if you want to test your applications with and without hardware accelerated OpenGL.

Disable XVideo Support

Disable XVideo support. In a dual independent head configuration, either the first display or the second display supports XVideo. Both displays can not support XVideo simultaneously. The default is XVideo support is enabled.

Disable XVideo Blend

Disable XVideo support using the 3D blend manager. This provides XVideo support in configurations that cannot be supported with overlay. For example, this is supported on both displays in a dual independent head setup. It is also supported when the display is rotated or flipped. Color key is only supported if ShadowFB is enabled and the VideoKey is defined. The default is XVideoBlend support is enabled.

Enable Frame Buffer Overlay Blending

When checked, this enables overlay blending with the framebuffer on both display outputs on US15W and when display mode resolution is 32-bit XRGB.

XVideo Color Key

This sets the color key for XVideo and XVideoBlend. This value is either a 24-bit value or a 16-bit value, depending on the pixel depth of the screen. The color key is always enabled for XVideo, even when it is not defined. The color key is always disabled for XVideoBlend unless both this option is defined and the ShadowFB option is enabled. The default color key for XVideo is 0x0000ff00. For XVideo Blend, the color key is disabled by default.
