NAME

Xrren2 − Renaissance Rendition II Smart Board Interface server for X11

SYNOPSIS

Xrren2 [ option ] ...

DESCRIPTION

Xrren2 is the server for INTER­ACTIVE X11 running on an INTER­ACTIVE UNIX Operating System, Version 2.2 or later, using the Renaissance Rendition II display adapter.  The Xrren2 server is able to provide an effective display area that is larger than the one provided by the standard Xrren2 display adapter.  See “panning” below for more ­details. 

Xrren2 operates on a 386- or 486-based ISA or EISA computer.  It is normally invoked by a program such as xinit(1) or by the INTER­ACTIVE Easy Windows Environment. 

VT flipping is supported on this board.  (For additional information on virtual terminals and VT flipping, refer to the section “USING VIRTUAL TERMINALS” in the “INTERACTIVE UNIX Operating System Primer” in the INTERACTIVE UNIX System Guide for New Users.) Note that only one Xrren2 server can be run at a time. 

OPTIONS

−config configuration file
Specifies an alternate configuration file to be used instead of /usr/lib/X11/Xconfig. 

Other options are described under Xserver(1).

CONFIGURATION

The Info field in the configuration file (see Xconfig(5)) is used to specify options to Xrren2. This field should be a quoted string consisting of 0 or more keyword parameters, for example, "config_mode=0 pan=y". 

The configuration mode specifies the board configuration (resolution, pixel size, monitor, etc.) that will be used.  The following table describes the requirements for each of the monitor types:

Monitors Supported
Monitor Horizontal Vertical
Type Frequency Frequency
High 54.0 kHz 66.0 Hz
High Interlaced 35.5 kHz 43.5 Hz
Medium 37.0 kHz 60.0 Hz
Alt 48.0 kHz 60.0 Hz
Low 31.5 kHz 60.0 Hz

The monitor to be used with the Renaissance Rendition II may limit the available configuration modes.  The presence of the Additional VRAM Memory on the Rendition II board allows for additional screen area to pan.  If the Additional VRAM Memory is not present, then the entire 1024x768 resolution with 256 colors in modes 3, 5, 7, and 9 cannot be displayed due to insufficient memory.  In this case, the height will be 512 rows. 

The following table describes the configuration modes available:

9 High Interlaced 1024 768* 8 256 1024 512 1024 768 1024 1024

* The height will be 512 if additional VRAM memory is not present. 

The Xrren2 server supports panning of the visible screen area across a larger effective screen.  Panning the visible screen means using the screen as a window onto a larger display area.  When the mouse travels to an edge of the screen, the entire screen will appear to slide over the full display area.  This allows users without “extended” display adapters to have a larger work area than would otherwise be available.  Panning can be enabled by adding the keyword parameter pan=y or disabled by adding the keyword parameter pan=n into the Info field of the configuration file. 

The display width and height can be made smaller by specifying the keyword parameters display_width=nnn and display_height=nnn.  This may be useful in limiting the panned area so that the screen does not become too large to be useful when using a window manager such as Motif, which utilizes pop-up boxes.  It is not possible to increase either the width or the height of the display. 

The screen width and height can be specified with the keywords screen_width=nnn and screen_height=nnn.  This specifies the dimensions of the screen in inches.  This value must be an integer. 

For example, the following configuration file entry fully specifies display 0 to be a standard Xrren2 console display 640 pixels wide by 480 pixels high with 16 colors, with panning enabled, running on a screen 12 inches wide and 9 inches high:

display RREN2 "config_mode=0 pan=y screen_width=12 screen_height=9" 0 /dev/console
keyboard AT 101 0 /dev/console:/dev/vt%02d
mouse LOGI-S "1200 3" 0 /dev/tty00
