Restrictions and Limitations
This section provides information on the limitations and restrictions of the HP PCI AMD Radeon
7000 Graphics Adapter hardware and software.
No Accelerated 3D Support
The HP PCI AMD Radeon 7000 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 PCI
AMD Radeon 7000 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 PCI AMD Radeon 7000 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”
