    CONFIGURATION DETAILS

           Please refer to xorg.conf(5) for general configuration  details.   This
           section only covers configuration details specific to this driver.
    
           Detailed  information  on  all  supported  options  can  be obtained at
           http://www.winischhofer.eu/linuxsisvga.shtml
    
           This manpage only covers a subset of the supported options.
    
           1. For all supported chipsets
    
           The following driver options are supported on all chipsets:
    
           Option "NoAccel" "boolean"
                  Disable or enable  2D  acceleration.  Default:  acceleration  is
                  enabled.
    
           Option "HWCursor" "boolean"
                  Enable or disable the HW cursor. Default: HWCursor is on.
    
           Option "SWCursor" "boolean"
                  sive.  Default: no reflection.
    
           Option "CRT1Gamma" "boolean"
                  Enable  or disable gamma correction. (On the 300 and 315/330/340
                  series, this option only affects CRT1 output).   Default:  Gamma
                  correction is enabled.
    
           2. Old series specific information
    
           The  driver will auto-detect the amount of video memory present for all
           these chips, but in the case of the 6326, it will limit the memory size
           to  4MB. This is because the 6326's 2D engine can only address 4MB. The
           remaining memory seems to be intended for 3D texture data,  since  only
           the 3D engine can address RAM above 4MB. However, you can override this
           limitation using the "VideoRAM" option in the Device  section  if  your
           board  has  more than 4MB and you need to use it. However, 2D accelera-
           tion, XVideo and the HWCursor will be disabled in this case.
    
           For the 6326, the driver has two built-in modes  for  high  resolutions
           which  you  should  use  instead  of  the default ones. These are named
           "SIS1280x1024-75" and "SIS1600x1200-60" and they will be added  to  the
           list  of  default  modes.  To  use these modes, just place them in your
           Screen section. Example:
    
           Modes "SIS1600x1200-60" "SIS1280x1024x75" "1024x768" ...
    
           Of these modes, 1280x1024  is  only  available  at  8,  15  and  16bpp.
           1600x1200 is available at 8bpp only.
    
           TV support for the 6326
    
           TV output is supported for the 6326. The driver will auto detect a con-
           nected TV and in this case add the following display modes to the  list
           of  available display modes: "PAL800x600", "PAL800x600U", "PAL720x540",
           "PAL640x480", "NTSC640x480",  "NTSC640x480U"  and  "NTSC640x400".   Use
           these modes like the hi-res modes described above.
    
           The following driver Options are supported on the old series:
    
           Option "TurboQueue" "boolean"
                  Enable or disable TurboQueue mode.  Default: off for SIS530/620,
                  on for the others
    
           Option "FastVram" "boolean"
                  Enable or disable FastVram mode.  Enabling this sets  the  video
                  RAM  timing  to  one  cycle  per  read  operation instead of two
                  cycles. Disabling this will set two cycles for  read  and  write
                  operations.  Leaving  this  option  out  uses the default, which
                  varies depending on the chipset.
    
           Option "NoHostBus" "boolean"
                  (SiS5597/5598 only). Disable CPU-to-VGA host bus  support.  This
                  set by a jumper on the card.
    
           Option "TVXPosOffset" "integer"
                  (6326 only) This option allows tuning the horizontal position of
                  the image for TV output. The range is from -16 to 16. Default: 0
    
           Option "TVYPosOffset" "integer"
                  (6326 only) This option allows tuning the vertical  position  of
                  the image for TV output. The range is from -16 to 16. Default: 0
    
           Option "SIS6326TVEnableYFilter" "boolean"
                  (6326 only) This option allows enabling/disabling the Y (chroma)
                  filter for TV output.
    
           Option "SIS6326TVAntiFlicker" "string"
                  (6326  only)  This  option  allow  enabling/disabling  the  anti
                  flicker facility for TV output.  Possible  parameters  are  OFF,
                  LOW,  MED, HIGH or ADAPTIVE.  By experience, ADAPTIVE yields the
                  best results, hence it is the default.
    
           2. 300 and 315/330/340 series specific information
    
           The 300 and 315/330/340 series, except the XGI Z7, feature two CRT con-
           trollers  and  very  often come with a video bridge for controlling LCD
           and TV output. Hereinafter, the term CRT1 refers to the VGA  output  of
           the  chip,  and  CRT2 refers to either LCD, TV or secondary VGA. Due to
           timing reasons, only one CRT2 output can be active at  the  same  time.
           But  this  limitation does not apply to using CRT1 and CRT2 at the same
           time which makes it possible to run the driver in dual head mode.
    
           The driver supports the following video bridges:
    
           SiS301 SiS301B(-DH) SiS301C SiS301LV SiS302(E)LV
    
           Instead of a video bridge, some machines have a third party LVDS trans-
           mitter  to  control  LCD  panels, and/or a Chrontel 7005 or 7019 for TV
           output. All these are supported as well.
    
           About TV output
    
           The driver fully supports standard (PAL, NTSC, PAL-N, PAL-M) S-video or
           composite  output as well as high definition TV (HDTV) output via YPbPr
           plugs.  For more information on HDTV, please consult the author's  web-
           site.
    
           As  regards  S-video  and CVBS output, the SiS301 and the Chrontel 7005
           only support resolutions up to 800x600. All others support  resolutions
           up  to  1024x768.  However, due to a hardware bug, Xvideo might be dis-
           torted on SiS video bridges if running NTSC or PAL-M at 1024x768.
    
           About XVideo support
    
           using two output devices of one card at the same time), but has  a  few
           advantages  which  make  me recommend it strongly over Xinerama. Please
           see http://www.winischhofer.eu/linuxsisvga.shtml for detailed  informa-
           tion.
    
           About dual-head support
    
           Dual  head mode with or without Xinerama is fully supported, be it with
           one card driving two outputs, be it two cards. Note that  colordepth  8
           is not supported in dual head mode if run on one card with two outputs.
    
           The following driver Options are supported on the 300  and  315/330/340
           series:
    
           Option "NoXVideo" "boolean"
                  Disable XV (XVideo) extension support.  Default: XVideo is on.
    
           Option "XvOnCRT2" "boolean"
                  On chipsets with only one video overlay, this option can used to
                  bind the overlay to CRT1 ( if a monitor is detected and if  this
                  option  is  either  unset  or set to false ) or CRT2 ( if a CRT2
                  device is detected or forced, and if this option is set to  true
                  ).  If  either only CRT1 or CRT2 is detected, the driver decides
                  automatically.  In  Merged  Framebuffer  mode,  this  option  is
                  ignored.  Default: overlay is used on CRT1
    
           Option "ForceCRT1" "boolean"
                  Force  CRT1  to be on of off. If a monitor is connected, it will
                  be detected during server start. However, some old monitors  are
                  not  detected  correctly. In such cases, you may set this option
                  to on in order to make the driver initialize  CRT1  anyway.   If
                  this  option  is  set  to off , the driver will switch off CRT1.
                  Default: auto-detect
    
           Option "ForceCRT2Type" "string"
                  Force display type to one of: NONE , TV , SVIDEO ,  COMPOSITE  ,
                  SVIDEO+COMPOSITE  ,  SCART , LCD , VGA ; NONE will disable CRT2.
                  The SVIDEO, COMPOSITE, SVIDEO+COMPOSITE and SCART parameters are
                  for  SiS  video bridges only and can be used to force the driver
                  to use a specific TV output connector (if present). For  further
                  parameters, see the author's website.  Default: auto detect.
    
           Option "CRT2Gamma" "boolean"
                  Enable  or disable gamma correction for CRT2. Only supported for
                  SiS video bridges. Default: Gamma correction for CRT2 is on.
    
           Option "TVStandard" "string"
                  Force the TV standard to either PAL or NTSC.  On  some  machines
                  with  630, 730 and the 315/330/340 series, PALM , PALN and NTSCJ
                  are supported as well. Default: BIOS setting.
    
           Option "TVXPosOffset" "integer"
           Option "SISTVYScale" "integer"
                  This option selects the vertical zooming level for TV output  in
                  the  following  modes:  640x480,  800x600.  On  the  315/330/340
                  series, also 720x480, 720x576 and 768x576. The range is from  -4
                  to 3. Only supported on SiS video bridges. Default: 0
    
           Option "CHTVOverscan" "boolean"
                  On  machines  with  a  Chrontel  TV encoder, this can be used to
                  force the TV mode to overscan or underscan.  on means  overscan,
                  off means underscan.  Default: BIOS setting.
    
           Option "CHTVSuperOverscan" "boolean"
                  On machines with a Chrontel 7005 TV encoder, this option enables
                  a super-overscan mode. This is only supported if the TV standard
                  is  PAL. Super overscan will produce an image on the TV which is
                  larger than the viewable area.
    
           The driver supports many more  options.  Please  see  http://www.winis-
           chhofer.eu/linuxsisvga.shtml for more information.
    
           3. 300 series specific information
    
           DRI  is  supported  on  the  300 series only. On Linux, prior to kernel
           2.6.3, DRI requires the kernel's SiS framebuffer driver ( sisfb ).  The
           SiS DRM kernel driver as well as the SiS DRI client driver are required
           in any case.
    
           Sisfb, if installed and running, takes care of  memory  management  for
           texture data. In order to prevent the X Server and sisfb from overwrit-
           ing each other's data, sisfb reserves an amount of video memory for the
           X driver.  This amount can either be selected using sisfb's mem parame-
           ter, or auto-selected depending on the amount of total video RAM avail-
           able.
    
           Sisfb  can  be used for memory management only, or as a complete frame-
           buffer driver. If you start sisfb with a valid  mode  (ie  you  gain  a
           graphical console), the X driver can communicate with sisfb and doesn't
           require any manual configuration for finding out about the video memory
           it is allowed to use.
    
           However, if you are running a 2.4 series Linux kernel and use sisfb for
           video memory management only, ie you started sisfb with  mode=none  and
           still have a text mode console, there is no communication between sisfb
           and the X driver. For this purpose, the
    
           Option "MaxXFBMem" "integer"
    
           exists. This option must be set to the same value  as  given  to  sisfb
           through  its  "mem"  parameter, ie the amount of memory to use for X in
           kilobytes.
    
           If you started sisfb without the mem argument, sisfb will reserve
           If the option is omitted, DRI will have no memory assigned, and all DRI
           applications will quit with errors like "failed to  allocate  Z-buffer"
           or the like.
    
           Option "DRI" "boolean"
                  This option allows enabling or disabling DRI. By default, DRI is
                  on.
    
           Option "AGPSize" "integer"
                  This option allows selecting the amount of AGP memory to be used
                  for DRI.  The amount is to be specified in megabyte, the default
                  is 8.
