sisusb - SiS USB video driver
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.
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(5x)
for general configuration details and
for more information. This manpage only covers a subset of the
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"
- 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).
