DESCRIPTION

   sisusb  is  an  Xorg  driver for SiS (Silicon Integrated Systems) video
   chips that are connected via a Net2280-based USB dongle. The driver  is
   not  accelerated,  but provides support for colordepths of 8, 16 and 24
   bpp as well as Render and other extensions.

SUPPORTED HARDWARE

   The sisusb driver supports USB  video  cards  based  on  the  following
   chipsets:

   SiS315E/PRO

   The  SiS315E/PRO  features  two  CRT  controllers.  However, in its USB
   version, only the first output, referred to as "CRT1", is being used.

CONFIGURATION DETAILS

   Please refer to xorg.conf(5) for general configuration details  and  to
   sis(4)  for  more information. This manpage only covers a subset of the
   supported options.

   Detailed information on  all  supported  options  can  be  obtained  at
   http://www.winischhofer.at/linuxsisusbvga.shtml

   Please  note  that  this  driver requires a Linux kernel driver as well
   which is included in Linux 2.6.12 and later, as well  as  available  at
   the aforementioned website.

   The following driver Options are supported:

   Option "HWCursor" "boolean"
          Enable  or disable the hardware cursor. It is not recommended to
          disable the hardware cursor as this will increase the amount  of
          data transferred over the USB. Default: HWCursor is on.

   Option "SWCursor" "boolean"
          The  opposite of HWCursor. This enables or disables the software
          cursor. This sort of cursor is slower because the  pointer  must
          be  painted into the graphics display. This increases the amount
          of  data  transferred  over  the  USB  significantly.   Default:
          SWCursor is off.

   Option "CRT1Gamma" "boolean"
          Enable  or  disable gamma correction.  Default: Gamma correction
          is on.

   Option "DisconnectTimeout" "integer"
          This  option  determines  how  the  driver  will  react   to   a
          disconnection  of the USB device. If the integer supplied is -1,
          the  driver  will  abort   the   X   server   immediately   upon
          disconnection.  If  the  value given is 0, the driver will probe
          for a re-connection every 2 seconds and in case  the  device  is
          detected, re-establish the display. If the value is greater than
          0, the driver will do this re-probing within the given number of
          seconds  and  abort  the server if it does not detect the device
          within this time-out.  Default:  0  (probe  forever  for  device
          reconnection).

KNOWN BUGS

   none.
