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 testing 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  experimentally.   Default:  Use  display  active  when  X
              started.

       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  "AccelMethod"  "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 accelerate the
              X Render extension.  Default: "XAA".
