A package such as Xinerama might be of interest; support for virtual stacking of multiheaded X Windows displays is available in DECwindows releases more current than V1.2-6. Please see the DECwindows
documentation:
https://docs.vmssoftware.com/vsi-decwin ... ent-guide/ (for current DECwindows releases) for details of configuring and using Xinerama.
Older implementations of DECwindows such as V1.2-6 have a less flexible relationship among multiple screens, and typically assume a horizontal organization. Both left-to-right and right-to-left can be configured.
By default, whichever physical screen is X Windows screen 0 will be the default application screen though this can be changed with the SET DISPLAY command or with the default application screen mechanism via the symbol DECW$APPSSCREEN within the file:
Code: Select all
SYS$MANAGER:DECW$PRIVATE_APPS_SETUP.COM
For example, if you want the login box to appear on the right-side screen in a typical two-headed multi-headed system, add the line:
into DECW$PRIVATE_APPS_SETUP.COM.
With Xinerama, you have full flexibility to locate the adjacencies among the various screens as desired, and vertical orientations among the available DECwindows X Windows screens are supported.
Do ensure you have installed the current ECO kit for the particular DECwindows release in use, as well as current ECOs for OpenVMS.
