No Accelerated 3D Support The HP Integrity rx2800 i2 2D Graphics Adapter does not support accelerated 3D (e.g. OpenGL). Multiple Colormaps Multiple installed colormaps in depth 8 PseudoColor visual are not supported. The HP Integrity rx2800 i2 2D Graphics Adapters support only one installed colormap at one time. Exceeding this limit will cause colormap "flashing". Applications should not install or uninstall colormaps themselves. The window manager should perform these actions. However, the application is responsible for providing the window manager with hints as to which colormaps to install or uninstall. You provide this information using the following Xlib function: XSetWMColormapWindows (). This function sets the WM_COLORMAP_WINDOWS property for a given window. Default Visual Information The HP Integrity rx2800 i2 2D Graphics Adapter can only support one visual type at one time. Supported default visual types are 8-bit PseudoColor and 24-bit TrueColor. The default depth and visual class is 24-bit TrueColor. To change the default visual, you must edit the Xserver's configuration file which is located at: /etc/X11/XF86Config. The depth is set in the Screen section of the XF86 configuration file. There also needs to be a Display subsection with the correct depth. For example, the following lines will select a 24-bit default visual: Section "Screen" Identifier "Screen 0" DefaultDepth 24 [...] SubSection "Display" Depth 24 [...] EndSubSection SubSection "Display" Depth 8 [...] Restrictions and Limitations 15

Restrictions and Limitations
This section provides information on the limitations and restrictions of the HP Integrity rx2800
i2 2D Graphics Adapter hardware and software.
No Accelerated 3D Support
The HP Integrity rx2800 i2 2D Graphics Adapter does not support accelerated 3D (e.g. OpenGL).
Multiple Colormaps
Multiple installed colormaps in depth 8
PseudoColor
visual are not supported. The HP Integrity
rx2800 i2 2D Graphics Adapters support only one installed colormap at one time. Exceeding this
limit will cause colormap “flashing”.
Applications should not install or uninstall colormaps themselves. The window manager should
perform these actions. However, the application is responsible for providing the window manager
with hints as to which colormaps to install or uninstall. You provide this information using the
following
Xlib
function:
XSetWMColormapWindows ()
. This function sets the
WM_COLORMAP_WINDOWS
property for
a given window.
Default Visual Information
The HP Integrity rx2800 i2 2D Graphics Adapter can only support one visual type at one time.
Supported default visual types are 8–bit
PseudoColor
and 24–bit
TrueColor
. The default
depth and visual class is 24–bit
TrueColor
. To change the default visual, you must edit the
Xserver's configuration file which is located at:
/etc/X11/XF86Config
.
The depth is set in the
Screen
section of the
XF86
configuration file. There also needs to be a
Display
subsection with the correct depth. For example, the following lines will select a 24–bit
default visual:
Section
