For a list of fixes included in this release as well as other MKS
X/Server releases, see Fixed Problems
below. Details on the new features of this release can be found in
the following sections:
OpenSSL updated to version 1.0.2
OpenSSL has been updated to 1.0.2.
Windows Vista support dropped.
Due to the fact that Vista does not have support for SHA256 code signing certificates, and an inability to purchase SHA1 code signing certificates, support for Windows Vista has been dropped (both 32 and 64-bit editions).
Windows Server 2003 support dropped.
With this release, support for Windows Server 2003 has been dropped (both 32 and 64-bit editions).
Build environment updated.
With this release our build environment was updated to use a newer compiler. Normally this is not of interest to end-users except for the fact that future hot fixes will be much more version specific than they have been in the past.

Installing PTC X/Server
If you have SCO XVision Eclipse, you must
it, or install PTC X/Server on another machine.
When installing PTC X/Server you must install from an account
with local or domain administrator privileges. You do not need to
be an Administrator, but your login ID must be a member of the
local or domain Windows Administrators group before you can install.
All PTC X/Server products share a common installer. If you are
installing from a CD, insert the PTC X/Server distribution CD; the
installer should start automatically. If you are installing from
an electronic distribution, run the self-extracting installer.
To install PTC X/Server, click the Install X/Server button
and follow the instructions on the dialogs that appear.
Note: You should turn off all virus protection software
before installing PTC X/Server. Such software can sometimes cause
the installation to be interrupted and rolled back. Once you have
installed PTC X/Server, you can turn virus protection back on.

For step-by-step installation instructions and information on
administrative and silent installations for PTC X/Server see
If you are installing a patch for PTC X/Server and PTC MKS Toolkit on the same machine, PTC recommends applying
the PTC MKS Toolkit patch to update the shared components before applying the PTC X/Server patch. It is not an
error to install the PTC XServer patch first, but you may be asked to reboot after patch install is complete.
Installing PTC MKS Toolkit first will reduce the risk that a reboot will be needed.
For step-by-step patch installation instruction for PTC X/Server see
Uninstalling PTC X/Server
Uninstalling PTC X/Server
To uninstall PTC X/Server, use the following procedure:
- From the Control Panel select Programs and Features.
- Remove PTC X/Server.
You must reboot your system before reinstalling PTC X/Server.
Uninstalling SCO XVision Eclipse
- From the Control Panel run Add/Remove Programs.
- Remove SCO XVision Eclipse. (This is only necessary if the
XVision X server is installed. This X Server was normally only
installed with previous versions of MKS Toolkit for
Interoperability and MKS Toolkit for Enterprise Developers.)
You must reboot your system before reinstalling PTC X/Server.
Activating PTC XServer
PTC XServer version 10.1 is copy protected and requires activation
against the MKS Activation Server (located at
to operate. The software is node fixed (that is, it is attached to a
single computer system) and user counted (the Named Authenticated
Users must be specified and are enforced). This activation takes place
after installation, so you need to plan your product rollout or
do not find yourself with unactivated software on users' machines.
Older versions of MKS X/Server permitted a single serial number to be
installed on multiple machines. For example 5 one user licenses could
have been installed using the first serial number and still remained
true to the license. Activation enforces the exact words of the
PTC Shrink Wrap License Agreement such that you will either have to
install those 5 different Serial Numbers on 5 different machines or
ask PTC Sales to consolidate them into a single Serial Number with 5 licenses.
Furthermore, you could request version upgrade media on a single Serial Number
and then used that media to upgrade machines with a different Serial Number.
This will no longer work. You must request that each Serial Number be upgraded
to the new release so that it may be activated with the new media. Failure to do
so will result in an activation error.
If you have some serial numbers under a valid Support Contract and
some that are not, and they have not been retired, you will be
unable to update any of your serial numbers until you bring all
licenses in use under a valid Support Contract, or retire unused licenses
permanently, or submit to PTC Sales in writing, you will not
update said serial numbers to any later version, unless you purchase
an update license at a later date.

We, the PTC XServer Product Team, sincerely value and appreciate
your business and want to do everything we can to ensure a
successful implementation of our products.
The following known issues exist in PTC X/Server:
- Overlay Planes using NVIDIA Cards on Vista.
- Currently, issues exist with using Overlay Planes on
systems with NVIDIA cards running Windows Vista. To implement
Overlay Planes, X11 uses two separate Win32 windows (one for
the main plane and one for the overlay). Normally, Windows
expects one window with two layers, so problems can result.
There are two approaches to dealing with this issue.
This issue has been submitted to NVIDIA and their development
group is looking into the problem as NVIDIA bug number 479862.
- Do not initialize the main plane. This results in a GPF
- Initialize the main plane. This works on all systems
except those using NVIDIA cards and running Windows
Vista. On Windows Vista, the main plane of the overlay
window is not transparent and is 100% black, thus
obscuring the main plane behind it.
- Wandering Overlay Planes with NVIDIA Cards.
- On systems using an NVIDIA video card and running Windows
XP, 2003, or Vista, moving the main window causes the overlay
to wander with respect to its parent. The main window itself
is not moving. However, if the display is repainted, everything
is where it is supposed to be. For this reason, the overlay
plane is currently hidden during such a move (when full window
drag is enabled) and shown again once it reaches its
destination. Once Microsoft provides a fix for this problem
(Microsoft SXR081104600800), an environment variable will be
available to turn this behavior on and off.
- NuTCRACKER Platform Applications and Black Screens with NVIDIA Cards.
- When PTC X/Server is running on a system with a NVIDIA
video card and has both Hardware Acceleration and Direct
Rendering enabled, a request to use direct rendering from a
NuTCRACKER Platform application using OpenGL results in
nothing but a black screen. Disabling either Hardware
Acceleration or Direct Rendering should solve the problem.
NVIDIA is aware of the issue and questions about the
availability of a fix should be referred to them.
- NuTCRACKER Platform Applications and Direct Rendering
- When direct rendering is enabled for a NuTCRACKER
Platform application that uses OpenGL and an XServer is set
to use Direct Rendering, there
are times (very random) when the client application appears
to freeze when exiting (CTRL-C does not work and you must use
kill -9 command to force it to exit). In this case,
the Microsoft Win32 library OpenGL32.dll is waiting for a thread to
set a variable. This variable will never be set, since during the
DLL_PROCESS_DETACH, only one thread remains
running. This has been reported to Microsoft as
SRX081104600852 and appears only to be a problem when running
Windows XP, Windows 2003, and Windows 2003 R2. On Windows
Vista, you may see a slight delay at process exit but the
process does exit.
- Connecting to CDE on Solaris Using IPv6.
- You must use either use an IPv4 IP address or disable
IPv6 XDMCP when connecting to an IPv6-enabled Solaris
system running CDE. You can disable IPv6 XDMCP by checking
the Disable IPv6 on the XDMCP Advanced Settings
- XRemote and RPS.
- If you wish to use Remote Program Starter (RPS) to
start X clients over XRemote, you must manually set the
display name for the RPS command to match the XRemote proxy
- Do not use a font server while recording an X session.
- Terminal Emulators.
- When using an embedded emulator in-place, only a limited
implementation of the emulator toolbar support is available.
- When using an emulator in an ActiveX document container
application, the emulator's printing facilities are not
- When using an embedded emulator in-place in Microsoft Word,
or in an ActiveX document container application, the emulator's
context help does not work.
- To upgrade desktop VT320 applications, the VT420 emulator
must be installed.
- Multiuser Windows environments.
- PTC X/Server Printing does not work on Windows 2000
or Windows Terminal Server running in multi-user mode.
You can use LPD Printing in these environments.
- PTC X/Server 3D.
- Backing store shouldn't be used with
the GLX extension.
- OpenGL extensions are not available.
- The GLX extension is enabled by default. The
GLX extension can be disabled using the PTC X/Server
- If you experience problems with colors when
running OpenGL applications on a 256 color display,
setting the X/Server default visual class to TrueColor
may improve the situation.
To do this, choose:
X/Server Properties > Color tab > Let me specify a particular default visual class.
- Matrox Millennium video cards running in 16-bit
color can prevent some OpenGL applications from
running or displaying correctly. Matrox has been
informed of this problem.
Please contact the correct Technical Support orginization based on the where you acquired the PTC X/Server.
