2.1 OpenVMS Display Device and Layered Product Interfaces
This section contains release notes that pertain to the OpenVMS display
device (SET DISPLAY) and DECwindows Motif layered product interfaces.
2.1.1 OpenVMS Display Device (SET DISPLAY)
This section contains notes pertaining to OpenVMS display devices
created and managed using the SET DISPLAY and SHOW DISPLAY commands.
For more information on these commands, see the HP OpenVMS DCL Dictionary: N--Z or online
188.8.131.52 SET DISPLAY/REVOKE Error Message is Misleading
The error message for revoking a cookie that has timed out is
misleading. The error message indicates there is a %SYSTEM-F-BADPARAM,
bad parameter value. This does not indicate the nature of the error.
184.108.40.206 I/O Error Displayed When Using SET DISPLAY/REVOKE
Using the SET DISPLAY/REVOKE command to revoke a generated, trusted, cookie can sometimes result in an I/O error similar to the following:
XIO: fatal IO error 65535 (connection aborted) on X server ":0.0" after 10 requests (8 known processed) with 0 events remaining.
This error results from the cookie being used by the SET DISPLAY/REVOKE command to connect to the server. Revoking the cookie breaks the connection to the display server.
Although the error appears fatal, the revoke operation actually
220.127.116.11 Display Devices Not Deleted Upon Exit
When creating user-mode display devices with the DCL SET DISPLAY command, note that any unused devices may not be deleted when you log out of DECwindows Motif. Display devices created with SET DISPLAY are seen as permanent devices until used by an X client application and are not destroyed upon exit.
To avoid this problem, create supervisor-mode display devices.
This section contains release notes related to the DECwindows Motif
interface to DECTPU.
18.104.22.168 Small Display Monitors and DECTPU
When running DECTPU for DECwindows Motif on small display monitors, the main window can be less than fully visible.
To correct this condition, follow these steps:
Tpu.Tpu$MainWindow.X: 0 Tpu.Tpu$MainWindow.Y: 0 Tpu.Tpu$MainWindow.Rows: 21 Tpu*condensedFont: on Tpu*fontSetSelection: 1
$ DEFINE TPU$DEFAULTS SYS$LOGIN:EVE_SMALL_WINDOW.DAT $ EDIT/TPU/INTER=DECWINDOWS LOGIN.COM
This section contains release notes that pertain to the general
DECwindows Motif user environment. This includes corrections,
restrictions, and known problems that are common to both the
New Desktop and the Traditional DECwindows Desktop environments.
2.2.1 Web Browser Support
The HP Secure Web Browser (SWB) is the officially supported web browser for the HP OpenVMS Alpha and HP OpenVMS I64 operating systems. SWB is a licensed part of these operating systems and is based on the Mozilla Web Browser, which is designed for standards compliance, performance, and portability.
The OpenVMS Alpha version of the browser is available from the following location:
This page contains installation and running instructions, as well as information about hardware and software prerequisites, system parameters, account quotas, and problem reporting.
The OpenVMS I64 version of the browser is a part of one or more of the OpenVMS I64 Operating Environments (OEs) and is included on the OE distribution media. See the HP OpenVMS I64 Software Product Description (SPD) for more information on the specific OE bundles available with this release of OpenVMS.
There may be instances where running Java applications from the SWB will cause the system to freeze briefly. This is due to the way the DECwindows X display server currently handles non-blocking write operations to a requesting client application. See Section 4.1.4 for more information on this restriction.
Previously, on systems running DECwindows Motif for OpenVMS Alpha Version 1.3 or higher, scaled bitonal images were displayed incorrectly. The top-right corner of the image would overlay the top-left quarter of the image.
