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.
