Xv256(1) —
NAME
Xv256 − 256-color VGA server for X11
SYNOPSIS
Xv256 [ option ] ...
DESCRIPTION
Xv256 is the server for INTERACTIVE X11 running on an INTERACTIVE UNIX Operating System Version 2.2 or later, using a VGA display adapter displaying 256 colors. Several “enhanced” versions of the VGA adapter standard are supported. The Xv256 server also supports SunRiver Corporation workstations.
Xv256 operates on a 386- or 486-based ISA, EISA, or Micro Channel computer. It is normally invoked by a program such as xinit(1) or by the INTERACTIVE Easy Windows Environment.
Xv256 supports a PseudoColor visual type when used with a color monitor and a GrayScale visual type when used with a monochrome monitor.
OPTIONS
Options are described under Xserver(1).
CONFIGURATION
Xv256 requires the Type field in the configuration file (see Xconfig(5)) to be V256.
The Info field is used to specify the board, resolution and the width and height of the attached monitor. The format of this field is:
"BOARD XPIXELSxYPIXELS WIDTHxHEIGHT"
The WIDTHxHEIGHT argument describes the size of the display and is specified in whole inches.
In addition to the supported boards listed in the following table, the Xvga server also supports VESA SVPMI description files. These files are found in the directory /usr/lib/X11/vesa/vga. To see a list of these boards, type:
sysadm configmgmt
When you are asked to select a VGA board manufacturer, select:
SVPMI description file
The following table shows the VGA boards and resolutions supported. (For a more current listing of supported graphic cards, see the INTERACTIVE UNIX Hardware Compatibility Guide.) All modes are in non-interlaced mode unless otherwise noted:

| 1. | Interlaced display. |
| 2. | For use on fixed frequency monitors such as IBM 8514 or Seiko 1430. |
| 3. | Alternate configuration providing a better display on some monitors. |
For example, the following configuration file entry fully specifies display 0 to be a standard VGA console display 320 pixels wide by 200 pixels high running on a screen 12 inches wide and 9 inches high:
| display | V256 | "VGA256 320x200 12x9" | 0.0 | /dev/console |
| keyboard | AT | 101 | 0.0 | /dev/console:/dev/vt%02d |
| mouse | LOGI-S | "1200 3" | 0.0 | /dev/tty00 |
SunRiver workstations are specified in the configuration file by indicating the SunRiver device name in place of /dev/console, i.e., /dev/st00 for the first SunRiver display. This example defines SunRiver VGA+ unit 0 as display 1 with a LOGITECH serial mouse on the DB-25 connector:
| display | V256 | "P256 640x400 12x9" | 1.0 | /dev/st00 |
| keyboard | AT | 101 | 1.0 | /dev/st00:/dev/st0%d |
| mouse | LOGI-S | "1200 3" | 1.0 | /dev/ser00 |
