       sisusb - SiS USB video driver

         Driver "sisusb"


       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.


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


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


       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

       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).
