DESCRIPTION
       trident  is  an  Xorg  driver for Trident video cards.  The driver is accelerated, and provides support for the following
       framebuffer depths: 1, 4, 8, 15, 16, and 24. Multi-head configurations are supported.  The XvImage extension is supported
       on TGUI96xx and greater cards.

SUPPORTED HARDWARE
       The trident driver supports PCI,AGP and ISA video cards based on the following Trident chips:

       Blade       Blade3D,  CyberBlade  series  i1,  i7  (DSTN),  i1,  i1 (DSTN), Ai1, Ai1 (DSTN), CyberBlade/e4, CyberBladeXP,
                   CyberBladeAi1/XP, BladeXP

       Image       3DImage975, 3DImage985, Cyber9520, Cyber9525, Cyber9397, Cyber9397DVD

       ProVidia    9682, 9685, Cyber9382, Cyber9385, Cyber9388

       TGUI        9440AGi, 9660, 9680

       ISA/VLBus   8900C, 8900D, 9000, 9200CXr, Cyber9320, 9400CXi, 9440AGi These cards have been ported but need further  test-
                   ing and may not work.

CONFIGURATION DETAILS
       Please  refer to xorg.conf(5) for general configuration details.  This section only covers configuration details specific
       to this driver.

       The following driver Options are supported:

       Option "SWCursor" "boolean"
              Enable or disable the SW cursor.  Default: off.

       Option "NoAccel" "boolean"
              Disable or enable acceleration.  Default: acceleration is enabled.

       Option "PciRetry" "boolean"
              Enable or disable PCI retries.  Default: off.

       Option "CyberShadow" "boolean"
              For Cyber chipsets only, turn off shadow registers. If you only see a partial display - this may be the option for
              you. Default: on.

       Option "CyberStretch" "boolean"
              For  Cyber chipsets only, turn on stretching. When the resolution is lower than the LCD's screen, this option will
              stretch the graphics mode to fill the entire LCD. Default: off.

       Option "ShadowFB" "boolean"
              Enable or disable use of the shadow framebuffer layer.  Default: off.

       Option "VideoKey" "integer"
              This sets the default pixel value for the YUV video overlay key.  Default: undefined.

       Option "TVChipset" "string"
              This sets the TV chipset. Options are CH7005 or VT1621.  Default: off.

       Option "TVSignal" "integer"
              This sets the TV signalling. Options are 0 for NTSC or 1 for PAL.  Default: undefined.

       Option "NoPciBurst" "boolean"
              Turn off PCI burst mode, PCI Bursting is on by default.  Default: off.

       Option "XvHsync" "integer"
              Override the default Horizontal-sync value for the Xv extension.  This is used to  center  the  Xv  image  on  the
              screen.  By default the values are assigned based on the video card.  Default: 0.

       Option "XvVsync" "integer"
              Override the default Vertical-sync value for the Xv extension.  This is used to center the Xv image on the screen.
              By default the values are assigned based on the video card.  Default: 0.

       Option "XvBskew" "integer"
              Override the default Bottom skew value for the Xv extension.  This is used to extend the Xv image on the screen at
              the bottom.  By default the values are assigned based on the video card.  Default: 0.

       Option "XvRskew" "integer"
              Override  the default Right skew value for the Xv extension.  This is used to extend the Xv image on the screen at
              the right.  By default the values are assigned based on the video card.  Default: 0.

       Option "Display" "string"
              Override the display.  Possible values are "CRT", "LCD" and "Dual".  Please note that this option is only  experi-

       Option "Display1400" "boolean"
              Inform driver to expect 1400x1050 display instead of a 1280x1024.  Default: off.

       Option "GammaBrightness" "string"
              Set  display  gamma  value  and brightness. "string" is "gamma, brightness", where gamma is a floating point value
              greater than 0 and less or equal to 10. brightness is an integer value greater or equal to 0 and  less  than  128.
              Default: gamma and brightness control is turned off.  Note: This is not supported on all chipsets.  Option "Accel-
              Method" "string" Choose acceleration architecture, either "XAA" or "EXA".  XAA is the  old  (but  stable)  XFree86
              based acceleration architecture.  EXA is a newer and simpler acceleration architecture designed to better acceler-
