+.SH DESCRIPTION
+.B trident
+is an XFree86 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.
+.SH SUPPORTED HARDWARE
+The
+.B trident
+driver supports PCI,AGP and ISA video cards based on the following
+Trident chips:
+.TP 12
+.B Blade
+Blade3D, CyberBlade series i1, i7 (DSTN), i1, i1 (DSTN), Ai1, Ai1 (DSTN),
+CyberBlade/e4, CyberBladeXP, CyberBladeAi1/XP, BladeXP
+.TP 12
+.B Image
+3DImage975, 3DImage985, Cyber9520, Cyber9525, Cyber9397, Cyber9397DVD
+.TP 12
+.B ProVidia
+9682, 9685, Cyber9382, Cyber9385, Cyber9388
+.TP 12
+.B TGUI
+9440AGi, 9660, 9680
+.TP 12
+.B ISA/VLBus
+8900C, 8900D, 9000, 9200CXr, Cyber9320, 9400CXi, 9440AGi
+These cards have been ported but need furthur testing and may not work.
+.SH CONFIGURATION DETAILS
+Please refer to XF86Config(__filemansuffix__) for general configuration
+details. This section only covers configuration details specific to this
+driver.
+.PP
+The following driver
+.B Options
+are supported:
+.TP
+.BI "Option \*qSWCursor\*q \*q" boolean \*q
+Enable or disable the SW cursor. Default: off.
+.TP
+.BI "Option \*qNoAccel\*q \*q" boolean \*q
+Disable or enable acceleration. Default: acceleration is enabled.
+.TP
+.BI "Option \*qPciRetry\*q \*q" boolean \*q
+Enable or disable PCI retries. Default: off.
+.TP
+.BI "Option \*qCyberShadow\*q \*q" boolean \*q
+For Cyber chipsets only, turn off shadow registers. If you only see
+a partial display - this may be the option for you. Default: on.
+.TP
+.BI "Option \*qCyberStretch\*q \*q" boolean \*q
+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.
+.TP
+.BI "Option \*qShadowFB\*q \*q" boolean \*q
+Enable or disable use of the shadow framebuffer layer. Default: off.
+.TP
+.BI "Option \*qVideoKey\*q \*q" integer \*q
+This sets the default pixel value for the YUV video overlay key.
+Default: undefined.
+.TP
+.BI "Option \*qNoPciBurst\*q \*q" boolean \*q
+Turn off PCI burst mode, PCI Bursting is on by default.
+Default: off.
+.TP
+.BI "Option \*qXvHsync\*q \*q" integer \*q
+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.
+.TP
+.BI "Option \*qXvVsync\*q \*q" integer \*q
+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.
+.TP
+.BI "Option \*qXvBskew\*q \*q" integer \*q
+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.
+.TP
+.BI "Option \*qXvRskew\*q \*q" integer \*q
+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.
+.TP
+.BI "Option \*qDisplay\*q \*q" string \*q
+Override the display.
+Possible values are \*qCRT\*q, \*qLCD\*q and \*qDual\*q.
+Please note that this option is only experimentally.
+Default: Use display active when X started.
+.TP
+.BI "Option \*qDisplay1400\*q \*q" boolean \*q
+Inform driver to expect 1400x1050 display instead of a 1280x1024.
+Default: off.
+.TP
+.BI "Option \*qGammaBrightness\*q \*q" string \*q
+Set display gamma value and brightness. \*q\fIstring\fP\*q is
+\*q\fIgamma\fP, \fIbrightness\fP\*q, where \fIgamma\fP is a floating
+point value greater than 0 and less or equal to 10. \fIbrightness\fP 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.
