Patch Installation Instructions:
-------------------------------- 
Refer to the man pages for instructions on using 'patchadd' and 'patchrm'
scripts provided with Solaris.  Any other special or non-generic
installation instructions should be described below as special
instructions.  The following example installs a patch to a standalone
machine:
 
	example# patchadd /var/spool/patch/104945-02
 
The following example removes a patch from a standalone system:
 
	example# patchrm 104945-02
 
For additional examples please see the appropriate man pages.

NOTE 1:
RFE 4293551 dtsession in xinerama mode should (optionally) not center
	    the logout dialog box
=====================================================================				 
Sun(tm) delivers a version of CDE that has been extended to provide
some basic support when run in multi-headed Xinerama mode.
 
This support is to make the positioning of the following CDE dialogs 
resource configurable:
        - Login (a.k.a. dtgreet)
        - Logout Confirmation
        - Unlock Display
        - Restart Workspace Confirmation 
        - Move/Resize Coordinates. 
 
The reason for making these dialogs configurable in terms of their
window positioning is obvious, they are all non-movable.  That is,
these dialogs are all centered in the logical screen regardless of the
number of physical monitors available.  Without the ability to
configure these dialogs, they will be split across monitors and will
cause many ease-of-use issues.
 
CDE patches (108921-08,109354-05,108919-05, or newer) and the Xsun patch
(108652-19, or newer), when installed together, allow the user to configure
the positioning of the previously mentioned dialogs using the following X
resources:
	xineramaDefaultFramebuffer
	xineramaCenterHintX
	xineramaCenterHintY
 
Resource Description
========================
 
If the xineramaDefaultFramebuffer resource has a value between 0 and
(n-1), within the Xinerama screen, then dialogs will be centered on
that framebuffer.
 
If the xineramaDefaultFramebuffer resource has a value of -1, then dialogs will 
be centered using the values in xineramaCenterHintX and xineramaCenterHintY.
 
To set resources system-wide, copy Xresources and sys.resources from
/usr/dt/config/C to /etc/dt/config/C and add the appropriate lines.
Setting resources in the Xresources file affects Login, while setting
them in sys.resources affects Logout Confirmation, Unlock Display,
Restart Workspace Confirmation, and Move/Resize Coordinates.
 
Note that the resources for dtlogin, and thus the position of the Login
dialog, cannot be set on a per-user basis on a single machine because
dtgreet is run from root before the user is identified.  The position
of the other dialogs can be set on a per-user basis by creating or
modifying the appropriate resource files in the user's HOME directory,
.Xdefaults.
 
The X resources have no effect if Xinerama is not being used or if
their default values are -1.
 
Example of using these resources
================================
 
The following are a few examples assuming a two-headed system.
 
1) To set Login, Logout Confirmation, Restart Workspace Manager
Confirmation, Unlock Display and the Resize/Move Coordinate dialogs
centered on the first screen:
 
*xineramaDefaultFramebuffer: 0
 
in both Xresources and sys.resources files. 
 
Alternatively to have these dialogs centered on the second screen:
 
*xineramaDefaultFramebuffer: 1
 
in both Xresources and sys.resources files.
 
2) If desired, these dialogs do not have to be centered on a particular
screen.  Instead you can position them anywhere within the entire
Xinerama screen by setting their X and Y coordinates.  Taking a
two-headed system, each screen is 1024 pixels high by 1024 pixels wide,
it is possible to place the dialogs in the lower left part of the
second screen.  To position the dialogs 100 pixels to the left of the
second screen and 200 pixels from the bottom, set the following
resources:
 
*xineramaDefaultFramebuffer: -1
*xineramaCenterHintX: 1124
*xineramaCenterHintY: 824
 
new resource
============
 
A new resource, dtsession*cacheColors, is introduced in this patch.
 
When this resource is set to True dtsession caches frequently used colors for
sharing between applications, improving desktop performance. If this resource
is set to False, bug 4349846 is fixed which allows remote machines running
non-Solaris versions of Unix to remote display Motif applications on
multiheaded Solaris machines.
 
The resource is set to True by default. It can be set to False by adding the
following line to the Dtsession resource file:
 
dtsession*cacheColors:  False
 
Please see the dtsession(1X) man page for instructions on how to edit 
resources for dtsession.
