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.
