The following enhancements are available from the New Desktop
environment with HP DECwindows Motif for HP OpenVMS Alpha Version 1.3.
1.3.1 Support for UNIX-Style Filenames
Starting with HP DECwindows Motif for HP OpenVMS Alpha Version 1.3, you have the ability to display file and device names in UNIX-style format in the File Selection widget and the File Manager (DTFILE).
When this feature is enabled, file and directory specifications are displayed according to UNIX pathname conventions, such as using slashes instead of square brackets to delimit directory trees. In addition, the case of device names is preserved when displaying UNIX-style pathnames versus being converted to uppercase.
The following sections briefly describe how to enable this feature.
1.3.1.1 Enabling in the File Selection Dialog Box
To enable the display of UNIX-style filenames in the File Selection dialog box, set one or more of the following logicals to a non-zero value:
These logicals can be defined system-wide by adding them to the SYS$MANAGER:SYLOGICALS.COM file, or defined on a per-user basis by adding them to each user's DECW$LOGIN.COM or LOGIN.COM file.
To force the File Selection dialog box to return selected filenames in
OpenVMS format while displaying them in UNIX format, define the logical
DECW$XM_UNIX_NAMES_TO_VMS. This enables other applications that rely on
filenames in OpenVMS format to interact successfully with the File
Selection dialog box while still displaying filenames in UNIX format.
1.3.1.2 Enabling in the File Manager (DTFILE)
To enable the display of UNIX-style filenames in the File Manager (DTFILE) set the logical CDE$DTFILE_UNIX_NAMES to a non-zero value.
This logical can be defined system-wide by adding it to the
SYS$MANAGER:SYLOGICALS.COM file, or defined on a per-user basis by
adding it to each user's DECW$LOGIN.COM or LOGIN.COM file.
1.3.2 Disabling the Suggested Password List
You can disable the display of the suggested password list when logging into New Desktop with an expired password.
To suppress the suggested password list, define the system logical CDE$NOGENPWD to a non-zero value, as follows:
$ DEFINE/SYSTEM CDE$NOGENPWD 1 |
You can now grant a DECwindows Motif user the ability to unlock a DECwindows Motif session paused using the Screen Lock function described in Section 4.2.1.
To specify the trusted user, define the system logical DECW$TRUSTED_UNPAUSE logical, as follows, where username represents the name of an OpenVMS Alpha user:
$ DEFINE/SYSTEM DECW$TRUSTED_UNPAUSE "username" |
With HP DECwindows Motif for HP OpenVMS Alpha Version 1.3, support for a range of new X Window System extensions has been added to the DECwindows X11 Display Server. The following sections describe the additional server management and configuration options available on OpenVMS Alpha Version 7.3--1 systems.
For additional information on managing DECwindows Motif systems, see
Managing DECwindows Motif for OpenVMS Systems.

If you plan on defining any of these parameters, do one of the following:
The following sections further describe each parameter. Note that these
parameters are intended for use on or with OpenVMS Alpha Version 7.3--1
systems only. For a description of additional X server parameters, see
Managing DECwindows Motif for OpenVMS Systems.
2.1.1 Extension Setup
While some extensions are a permanent part of the DECwindows X11 Display Server and are always enabled, some require activation through a parameter definition. Use the new parameters described in this section to set the range of active extensions on one or more DECwindows X11 Display Server systems.
See Section 2.2 for instructions on how to enable one or more X server extensions. For a brief description of the new extensions available with this release of the DECwindows X11 Display Server, see Section 3.5.
This parameter determines which loadable server extensions are enabled and active. The valid values for DECW$SERVER_EXTENSIONS are:
The default is "XIE,DEC-XTRAP,MULTI-BUFFERING,SEC_XAG." If you have user-written, third-party, or other HP X Window System extensions, you can use this parameter to enable the extensions at server startup.
To prevent contention over resources or server requests, some combinations of extensions should not be loaded on the same display server system. See the hp DECwindows Motif for hp OpenVMS Alpha Release Notes for the list of unsupported combinations of server extensions. |
The following parameter definition specifies the range of server extensions to enable:
Example
$ DECW$SERVER_EXTENSIONS == "XIE,DEC-XTRAP,XINERAMA,SEC_XAG,DBE" |
This parameter controls whether test extensions, XTEST and DEC-XTRAP, are enabled. Valid values for this parameter are T (True-disable) or F (False-enable) The default value is F.
The following parameter definition enables all test extensions:
Example
$ DECW$SERVER_DISABLE_TEST == "F" |
The XINERAMA extension (formerly known as Panoramix) is used to construct a multiheaded X Window system and have it function as a single virtual display. Use the parameters in this section to define and enable the screens in the display, control their order, and set the boundary and shape of the display.
By default, all screens in the display are enabled. You can use DECW$SERVER_ONLYSCREEN, DECW$SERVER_DISABLESCREEN to selectively remove one or more screens from the display. Disabled screens are not initialized and are not assigned a screen number. For instructions on how to configure a multiheaded display using the XINERAMA extension, see Section 2.3. For a brief description of the XINERAMA extension, see Section 3.5.1.9.
With a multiheaded system based on the XINERAMA extension, screens are initialized in alphabetical order according to their device name versus their physical position. Use this parameter to change the order in which the screens are initialized.
The following parameter definition changes the initialization order in a four-screen multiheaded display:
Example
$ DECW$SERVER_SCREENS == "GYB0,GYA0,GYD0,GYC0" |
With a multiheaded system based on the XINERAMA extension, you can choose to re-enable disabled screens in the display individually. This parameter enables the specified screen(s). The valid value ranges from 0 to 15, which represent the maximum number of screens supported by XINERAMA.
The following example enables the second screen (1) in a four-screen (0,1,2,3) multiheaded display:
Example
$ DECW$SERVER_ENABLESCREEN == "1" |
With a multiheaded system based on the XINERAMA extension, you can choose to disable each screen in the display individually. This parameter disables the specified screen. The valid value ranges from 0 to 15, which represents the maximum number of screens supported by XINERAMA.
Once a screen is disabled, it is no longer initialized as part of the display and is not assigned a screen number. Note that this changes the existing screen order and alters the display of any predefined edge attachments.
The following parameter definition disables the third screen (2) in a four-screen (0,1,2,3) multiheaded display:
Example
$ DECW$SERVER_DISABLESCREEN == "2" |
With a multiheaded system based on the XINERAMA extension, you can choose to enable individual screens in the display at the exclusion of all others. This parameter explicitly enables the specified screen(s) and disables all others. The valid value ranges from 0 to 15, which represents the maximum number of screens supported by XINERAMA.
The following parameter definition enables the second screen (1) and disables all other screens (0,2,3) in a four-screen (0,1,2,3) multiheaded display:
Example
$ DECW$SERVER_ONLYSCREEN == "1" |
With a multiheaded system based on the XINERAMA extension, edge controls are used to define the boundaries of the virtual display. This parameter determines to what screen(s) the left boundary of the display is attached. The values are determined by screen number, for example:
left-screen#, index-screen#, right-screen#
where index-screen# represents the number of the screen to which you want the boundary attached, left-screen# indicates the number of the screen directly to the left of the index, and right-screen# indicates the number of the screen directly to the right of the index. Repeat this pattern for each screen you to which you want the border attached. A value of -1 equates to none.
The following parameter definition specifies the left edge of a square, four-screen display arranged in the following order:
where the left edge of the second and fourth screens (indices 1 and 3) are attached to the first and third screens (0,2):
Example
$ DECW$SERVER_EDGE_LEFT == "-1,0,-1,2" |
With a multiheaded system based on the XINERAMA extension, edge controls are used to define the boundaries of the virtual display. This parameter determines to what screen the right boundary of the display is attached. The values are determined by screen number, for example:
right-screen#, index-screen#, left-screen#
where index-screen# represents the number of the screen to which you want the boundary attached, right-screen# indicates the number of the screen directly to the right of the index, and left-screen# indicates the number of the screen directly to the left of the index. Repeat this pattern for each screen you to which you want the border attached. A value of -1 equates to none.
The following parameter definition specifies the right edge of a square, four-screen display arranged in the following order:
where the right edges of the first and third screens (indices 0 and 2) are attached to the second and fourth screens (1,3):
Example
$ DECW$SERVER_EDGE_RIGHT == "1,-1,3,-1" |
With a multiheaded system based on the XINERAMA extension, edge controls are used to define the boundaries of the virtual display. This parameter determines to what screen the top boundary of the display is attached. The values are determined by screen number, for example:
top-screen#, index-screen#, bottom-screen#
where index-screen# represents the number of the screen to which you want the boundary attached, top-screen# indicates the number of the screen directly above the index, and bottom-screen# indicates the number of the screen directly below the index. Repeat this pattern for each screen you to which you want the border attached. A value of -1 equates to none.
The following parameter definition specifies the top edge of a square, four-screen display arranged in the following order:
where the top edges of the first and second screens (indices 0 and 1) are attached to the third and fourth screens (2,3):
Example
$ DECW$SERVER_EDGE_TOP == "2,3,-1,-1" |
With a multiheaded system based on the XINERAMA extension, edge controls are used to define the boundaries of the virtual display. This parameter determines to what screen the bottom boundary of the display is attached. The values are determined by screen number, for example:
bottom-screen#, index-screen#, top-screen#
where index-screen# represents the number of the screen to which you want the boundary attached, bottom-screen# indicates the number of the screen directly below the index, and top-screen# indicates the number of the screen directly above the index. Repeat this pattern for each screen you to which you want the border attached. A value of -1 equates to none.
The following parameter definition specifies the bottom edge of a square, four-screen display arranged in the following order:
where the bottom edges of the third and fourth screens (indices 2 and 3) are attached to the first and second screens (0,1):
Example
$ DECW$SERVER_EDGE_BOTTOM == "-1,-1,0,1" |
The X Keyboard extension (XKB) provides enhanced capabilities for defining the keyboard layout and audio feedback. It is a standard extension and includes all features previously provided by the proprietary AccessX extension. Use the new parameters in this section when using XKB to specify the settings for the X Keyboard layout files.
See Section 2.5 for instructions on how to load X Keyboard layout files. For a brief description of the extension, see Section 3.5.
This parameter enables the AccessX keyboard features for disabled users, such as sticky keys or slow keys. The valid values are 0 (disabled) or 1 (enabled). The default is 0.
The following example enables the AccessX features:
Example
$ DECW$SERVER_ENABLE_ACCESSX == "1" |
DECW$SERVER_XKEYBOARD_COMPILED_DIR
When using XKB, this parameter specifies the default directory for all compiled X Keyboard files. This directory is also where the server places any keymap files that it compiles on demand. The default is SYS$COMMON:[SYS$KEYMAP.XKB.COMPILED].
The following parameter definition changes the root directory to SYS$COMMON:[SYS$KEYMAP.XKB.SERVER1]:
Example
$ DECW$SERVER_XKEYBOARD_COMPILED_DIR == "SYS$COMMON:[SYS$KEYMAP.XKB.SERVER1]" |
DECW$SERVER_XKEYBOARD_DIRECTORY
When using XKB, this parameter specifies the default root directory for all X Keyboard files. All component source X Keyboard files are stored in subdirectories under this root directory. The default is DECW$SYSCOMMON:[SYS$KEYMAP.XKB].
The following parameter definition changes the root directory to SYS$COMMON:[SYS$KEYMAP.XKB]:
Example
$ DECW$SERVER_XKEYBOARD_DIRECTORY == "SYS$COMMON:[SYS$KEYMAP.XKB]" |
DECW$SERVER_XKEYBOARD_LOAD_MAP
When using XKB, this parameter loads the X Keyboard layout specified by DECW$SERVER_XKEYBOARD_MAP. The valid values for this parameter are 0 (disabled) or 1 (enabled). The default is 0. When this parameter is disabled, the DECwindows keyboard maps are used.
The following parameter definition loads the default X Keyboard layout file:
Example
$ DECW$SERVER_XKEYBOARD_LOAD_MAP == "1" |
When using XKB, this parameter specifies the default compiled X Keyboard layout file for your keyboard. The valid values for this parameter are the names of any compiled layout files that currently exist in the area specified by DECW$SERVER_XKEYBOARD_COMPILED_DIR. The default is DIGITAL_US_LK201.
The following parameter definition changes the X Keyboard layout to an alternate keyboard layout:
Example
$ DECW$SERVER_XKEYBOARD_MAP == "DIGITAL_US_LK401" |
When using XKB, this parameter specifies the number of milliseconds before a keystroke is first repeated. The valid values for this parameter are 0 to 1000. The default is 660.
The following parameter specifies the delay for keystroke repetition:
Example
$ DECW$SERVER_KEY_REPEAT_DELAY == "800" |
DECW$SERVER_KEY_REPEAT_INTERVAL
When using XKB, this parameter specifies the number of milliseconds between repeated keystrokes. The valid values for this parameter are 0 to 1000. The default is 40.
