Hi All,
Multiple X Display Support
Support for multiple X displays has been added by allowing users to run
multiple, simultaneous copies of the X server (limited only by available
memory and resources) as long as each copy has a unique display number. This
feature is particularly useful for users who would like to establish
multiple XDM (X Display Manager) sessions with different hosts.
The following command-line parameters are supported by the Exceed X Server
(exceed.exe):
-d <display#>
-m passive|query|indirect|broadcast
-h <hostname>
-w multiple|single
where <display#> represents the desired display number from 0 to 9999
inclusive and <hostname> represents the connect host for the XDMCP-query or
XDMCP-indirect startup modes.
For example, to start the Exceed X server in single window mode on display 1
with a startup mode of XDMCP-query to host xdmhost specify:
home\EXCEED -d 1 -m query -h xdmhost -w single
For a particular command-line parameter, if you would like the setting to
default to its current Xconfig value in the exceed.cfg configuration file,
omit its specification on the command-line.
The easiest way to startup multiple simultaneous copies of the Exceed X
Server is to use Xsession. In Xsession, you should uncheck the Run X Server
option, add a New Program of type Windows App to the session for every copy
of the X server in the session. For each X server in the session, make sure
either the command line is fully specified or the exceed.cfg value is
suitable, and make sure a unique display number is used. Enter the session
description text in the Description field, save the session, and install a
program shortcut to enable double-click startup of the session.
In a future release, Xsession will let you specify the startup of multiple
copies of the X server with different display numbers without the use of the
above command-line parameters. At this time their direct use will be
discouraged.
The current implementation of multiple X display support has several
restrictions or caveats. For example:
1 Since all X displays currently share the same configuration file, do
not make changes to your configuration while the X server is running.
2 Since only one X display can own the desktop/root window and the
configuration file is shared, do not enable the following Multiple Window
Mode Xconfig settings if you are using the multiple X display feature: Root
Mouse Actions to X, Root Drawing, and multiple screens. You can still use
the Root Mouse Actions to X toolbar button, but make sure the setting is
only selected for one X display at a time.
3 Colormaps are not shared between X displays which may result in
color flashing in 256 color video mode when you change the focus between
windows that are on different X displays.
4 Multiple copies of the X server cannot share a single log file. To
solve this problem, the name of the log file in your configuration file is
used to construct the log file name for each copy of the X server in the
following manner: if the log file name in your configuration file is
exceed.log, then each copy of the X server will use a log file whose name is
exceed<display#>.log
where <display#> is the display number of the X server.
To disable support for multiple X displays, set a value named
DisableMultipleXDisplays to 1 (DWORD) for the registry key
HKEY_LOCAL_MACHINE\Software\Hummingbird\Exceed\XServe r in the registry
database.
Mit freundlichen Grüßen / Best Regards

I'd like to simultaneously open sessions from my one PC on two different
UNIX machines. How do I do so?
Thanks
Philip
