ATI Fire GL4™ device-dependent information
ATI Fire GL4 provides 8 overlay planes, 48 image planes, a 24-bit Z buffer, 4 8-bit per channel
hardware colormaps and 1 10-bit per channel hardware colormap for use in gamma correction.
This device provides 2D hardware acceleration for most operations as well as 3D acceleration for
lighting, shading and texture mapping.
supported visuals
ATI Fire GL4 supports the following visuals:
Both the PseudoColor and TrueColor visuals are enabled by default. See

Description
enableDVI
Boolean
False
Enable DVI connector.
Qbs
Boolean
False
Enable quad-buffered stereo mode.
FrameLock
Boolean
False
Synchronizes frame buffer refresh
between multiple raster engines.
Setting this option causes the device
to become a slave to an external
timing generator (another device).
Commonly used to sync devices in a
stereoscopic display environment.
CountTransInOvlyVis
Boolean
True
When set to false, causes the X
Server to reserve the transparent pixel
index in all PseudoColor overlay
colormaps, thus reporting only 255
available entries.
TransparentIndex0
Boolean
False
Make the overlay transparent pixel
index 0 instead of 255.
DefaultVisualTrueColor
Boolean
True
Use TrueColor as the default visual
instead of PseudoColor.
