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.
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

The following driver
Options are supported:
-
Option "SWCursor"
"boolean"

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".
