The Question is: This is a DECWindows Question. Under Motif 1.2-6 is there a way to configure a two headed Alpha Station DS20 so that the pointer (cursor) will pass from one head to another in the vertical direction. This is the case for the application, where the monitors are positioned one on top of the other, making the most visually optiomal pathfor moving from on head to the another from the top of the bottom monitor and from the bottom ofthe top moni tor. I have checked every config file that I can find, looking for an entry that relates to this. Is this possible? The Answer is :
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 (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$APPSSCREEN within the file:
SYS$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:
$ DECW$APPSSCREEN==1
into DECW$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.
