Xgp(1) —
NAME
Xgp − 8514/A and Mach 32 Graphics Processor server for X11
SYNOPSIS
Xgp [ option ] ...
DESCRIPTION
Xgp is the server for INTERACTIVE X11 running on an INTERACTIVE UNIX Operating System Version 2.2 or later, using an 8514/A (or compatible) display adapter. Xgp operates on a 386- or 486-based ISA, EISA, or Micro Channel computer. It will normally be started by xinit(1) or by the INTERACTIVE Easy Windows Environment.
Xgp supports a PseudoColor visual type when used with a color monitor and GrayScale visual type when used with a monochrome monitor.
OPTIONS
Options are described in Xserver(1).
CONFIGURATION
Xgp requires the Type field in the configuration file (Xconfig(5)) to be 8514.
The Info field is used to specify the board, refresh rate (in Hz), resolution, number of colors to be used, and the width and height of the attached monitor. The format of this field is:
"BOARD REFRESH XPIXELSxYPIXELS COLORS WIDTHxHEIGHT"
Standard 8514/A compatible display adapters will support XPIXELSxYPIXELS values of either 1024x768 at 43 Hz or 640x480 at 60 Hz. Some extended 8514/A compatible displays will support an additional resolution of 1280x1024 and refresh rates of 60 or 70 Hz. See the table below for details. The WIDTHxHEIGHT argument is specified in whole inches. The colors argument may be either 16 or 256.
In addition to the supported boards listed in the following table, the Xgp server also supports VESA SVPMI description files. These files are found in the directory /usr/lib/X11/vesa/gp. To see a list of these boards, type:
sysadm configmgmt
When you are asked to select a VGA board manufacturer, select:
SVPMI description file
See the INTERACTIVE X11 Installation Instructions and Maintenance Procedures for more information about running sysadm configmgmt.
The following table shows the boards and resolutions supported. All modes are non-interlaced unless otherwise noted:
