DESCRIPTION

16       sisusb  is  an  Xorg  driver for SiS (Silicon Integrated Systems) video
17       chips that are connected via a Net2280-based USB dongle. The driver  is
18       not  accelerated,  but provides support for colordepths of 8, 16 and 24
19       bpp as well as Render and other extensions.
20

SUPPORTED HARDWARE

22       The sisusb driver supports USB  video  cards  based  on  the  following
23       chipsets:
24
25       SiS315E/PRO
26
27       The  SiS315E/PRO features two CRT controllers. However, in its USB ver‐
28       sion, only the first output, referred to as "CRT1", is being used.

CONFIGURATION DETAILS

31       Please refer to xorg.conf(5x) for general configuration details and  to
32       sis(4)  for  more information. This manpage only covers a subset of the
33       supported options.
34
35       Detailed information on  all  supported  options  can  be  obtained  at
36       http://www.winischhofer.at/linuxsisusbvga.shtml
37
38       Please  note  that  this  driver requires a Linux kernel driver as well
39       which is included in Linux 2.6.12 and later, as well  as  available  at
40       the aforementioned website.
41
42       The following driver Options are supported:
43
44       Option "HWCursor" "boolean"
45              Enable  or disable the hardware cursor. It is not recommended to
46              disable the hardware cursor as this will increase the amount  of
47              data transferred over the USB. Default: HWCursor is on.
48
49       Option "SWCursor" "boolean"
50              The  opposite of HWCursor. This enables or disables the software
51              cursor. This sort of cursor is slower because the  pointer  must
52              be  painted into the graphics display. This increases the amount
53              of data transferred over the USB significantly. Default:  SWCur‐
54              sor is off.
55
56       Option "CRT1Gamma" "boolean"
57              Enable  or  disable gamma correction.  Default: Gamma correction
58              is on.
59
60       Option "DisconnectTimeout" "integer"
61              This option determines how the driver will react to a disconnec‐
62              tion  of  the  USB  device.  If  the integer supplied is -1, the
63              driver will abort the X server immediately  upon  disconnection.
64              If  the value given is 0, the driver will probe for a re-connec‐
65              tion every 2 seconds and in case the  device  is  detected,  re-
66              establish  the  display.  If  the  value  is greater than 0, the
67              driver will do this re-probing within the given number  of  sec‐
68              onds  and  abort  the  server  if  it does not detect the device
69              within this time-out.  Default:  0  (probe  forever  for  device
70              reconnection).
