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.
