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 ver-
sion, 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: SWCur-
sor 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 disconnec-
tion 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-connec-
tion every 2 seconds and in case the device is detected, re-es-
tablish 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.
