Xcpqag(1) —
NAME
Xcpqag − COMPAQ AG1024 Smart Board Interface server for X11
SYNOPSIS
Xcpqag [ option ] ...
DESCRIPTION
Xcpqag is the server for INTERACTIVE X11 running on an INTERACTIVE UNIX Operating System, Version 2.2 or later, using the COMPAQ Advanced Graphics 1024 board display adapter. The Xcpqag server is able to provide an effective display area that is larger than the one provided by the standard Xcpqag display adapter. See “panning” below for more details.
If you want to change the I/O address of the COMPAQ AG1024 board, then you must reconfigure the cpqag kernel driver. To do this, see cpqag(7). This should only be necessary if you want to have the I/O base address be at 0280h instead of the default 0290h.
Xcpqag 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 Xcpqag 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 Xcpqag. 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 | Horinzontal/Vertical |
| Type | Frequency | Frequency | Sync Polarity |
| High | 54.0 kHz | 66.0 Hz | Positive |
| Alt | 48.0 kHz | 60.0 Hz | Negative |
| Low | 31.5 kHz | 60.0 Hz | Negative |
The monitor to be used with the COMPAQ AG1024 may limit the available configuration modes. The presence of the Optional Expansion Memory on the COMPAQ AG1024 card allows for additional screen area to pan. If the Optional Expansion Memory is not present, then the entire 1024x768 resolution with 256 colors in modes 3 and 5 cannot be displayed due to insufficient memory. In this case, 1024x512 resolution will be displayed.
The following table describes the configuration modes available:
| Configuration Modes Supported | |||||||||
| Without | With | ||||||||
| Memory | Memory | ||||||||
| Expansion | Expansion | ||||||||
| Configuration | Screen | Screen | Screen | Panning | Panning | Panning | Panning | ||
| Mode | Monitor | Width | Height | Depth | Colors | Width | Height | Width | Height |
| 0 | Low | 640 | 480 | 4 | 16 | 1024 | 1024 | 2048 | 1024 |
| 1 | Low | 640 | 480 | 8 | 256 | 1024 | 512 | 1024 | 1024 |
| 2 | High | 1024 | 768 | 4 | 16 | 1024 | 1024 | 2048 | 1024 |
| 3 | High | 1024 | 768* | 8 | 256 | 1024 | 512 | 1024 | 1024 |
| 4 | Alt | 1024 | 768 | 4 | 16 | 1024 | 1024 | 2048 | 1024 |
| 5 | Alt | 1024 | 768* | 8 | 256 | 1024 | 512 | 1024 | 1024 |
* The height will be 512 if the Memory Expansion is not present.
The Xcpqag 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 Xcpqag 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 | CPQAG | "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 |
