Xnews − Sony NEWS server for X Window System Version 11

SYNOPSIS

Xnews [ option ] ... 

DESCRIPTION

Xnews is the server for Version 11 of the X window system on Sony NEWS hardware.  It will normally be started by xinit(N), or perhaps by some script.

CONFIGURATIONS

Xnews operates under NEWS-OS versions 3.3 on All Sony NEWS Hardwear with Screen that have nfb(4) interface. Xnews supports multiple physical screens connected to a single server program.  "/etc/X?.screens" is read by the server at startup to determine information about the system screen configuration.  The "?" in "X?.screens" is a digit for the screen group that th screens are part of. 

Each screen is specified by a line in the file.  A line looks like:

<device path name><visual name of screen>

device path name
is the NEWS-OS device path-names associated with the screen.

visual name of screen
is the name of visual as specified in the X protocol for specifing CLUT type of screen.

Following are the name of current supported device and it’s visual. 

NWB-512A/dev/mfb0StaticGray
NWB-225A/dev/cfb0PseudoColor
NWB-514/dev/qfbm0GrayScale
NWB-251/dev/qfbc0PseudoColor
PWS-1550 etc./dev/pfbm0StaticGray
PWS-1560 etc./dev/pfbc0PseudoColor

It is assumed that the screens are physically placed from left to right in the order they appear in the file. The main pointing device roams between the screens as if thet were connected together in a ring by their left & right edges. Moving left from the left- most screen will place the pointing device on the right-most screen and and moving right from the right-most screen will place the pointing device on the left-most screen. 

Xnews read the file "/usr/lib/X11/keymap/?" at startup for supporting European keymap.  The "?" in "/usr/lib/X11/keymap/?" is a digit of the keymap number.
