MKS X/Server 8.2 - high performance X Server for Windows

MKS X/Server 8.2 is the latest version of MKS' newest interoperability product, MKS X/Server, a high performance X Server for Windows environments. For a list of fixes included in this release as well as other MKS X/Server releases, see Fixed Problems below. This release adds support for direct rendering, dramatically improving performance of graphically intensive applications, enhances support for remote access through Citrix, Microsoft Terminal Server, Remote Desktop, and VPN connections. Additional details about these and other enhancements can be found in the following sections:

Direct Rendering Support

MKS X/Server 8.2's direct rendering support enables applications migrated with MKS Toolkit for Enterprise Developers (both 32 and 64-bit editions), and using the MKS NuTCRACKER Platform to boost performance by communicating directly with the Windows OpenGL libraries.

To enable direct rendering, select MKS XServer > Configuration > MKS X Server Configuration from the Start menu and click on the Server icon. In the Extensions list, scroll down to GLX and check its box. With GLX highlighted, click the Properties button. On the GLX Properties dialog, check the Enable Direct Rendering box. The Help button on the dialog details the other GLX properties that can be set.

GLX Support

MKS X/Server 8.2 fully supports the 1.4 release of GLX.

Enhanced Support for Accelerated Open GL Applications

MKS X/Server 8.2 provides greater user control over Pixel Format to Visual mapping.

Remote Environment Support

Along with the existing certification of Microsoft Terminal Services and Remote Desktop environments, MKS X/Server 8.2 adds support for Citrix as well as an enhanced XDMCP implementation for easier connection over VPNs .

Installing MKS X/Server

If you have SCO XVision Eclipse, you must uninstall it, or install MKS X/Server on another machine.

When installing MKS 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 MKS X/Server products share a common installer. If you are installing from a CD, insert the MKS X/Server distribution CD; the installer should start automatically. If you are installing from an electronic distribution, run the self-extracting installer.

To install MKS 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 MKS X/Server. Such software can sometimes cause the installation to be interrupted and rolled back. Once you have installed MKS X/Server, you can turn virus protection back on.

For step-by-step installation instructions and an installation FAQ, see http://www.mkssoftware.com/support/install.asp.

Silent and Administrative Installations

For step-by-step installation instructions and information on administrative and silent installations for MKS X/Server see http://www.mkssoftware.com/support/install.asp.


Uninstalling MKS X/Server

Uninstalling MKS X/Server

To uninstall MKS X/Server, use the following procedure:

  1. From the Control Panel run Add/Remove Programs.

  2. Remove MKS X/Server.

You must reboot your system before reinstalling MKS X/Server.

Uninstalling SCO XVision Eclipse

  1. From the Control Panel run Add/Remove Programs.

  2. 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 MKS X/Server.


Known Issues

The following known issues exist in MKS X/Server:

  • MKS X/Server.
    • On Windows 2000, if you use "Focus Follows Mouse" with the "Leave Windows In Place" policy, you will see strange focus behavior when using MS-DOS Command Prompt windows.
    • On Windows 2000, if you use "Focus Follows Mouse" with the "Leave Windows In Place" policy, an Explorer window will have a corrupted title bar when you move the pointer out of the window. This does not affect the window itself. The window title is restored when the window receives focus again.


  • 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 server display.


  • XVSpy.
    • 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 available.
    • 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.


  • Vision Resume.
    • To use Vision Resume with XRemote, you must disable host access control for MKS X/Server.
    • When used with Vision Resume, Netscape might display "Sequence lost". You can safely ignore this message.
    • Some SCO UNIX X clients, such as scocal and scocolor, work with Vision Resume when MKS X/Server is using a PseudoColor display but not when it is using a TrueColor display.
      These clients will fail with third-party X servers when running with Vision Resume, unless the following lines are appended to the server's rgb.txt file (for example, /usr/lib/X11/rgb.txt):
      203 203 192            scoBackground
      11  0   113            scoForeground
      255 240 248            scoTopShadow
      255 206 137            scoActiveBackground
      43  45  49             scoActiveForeground
      254 222 255            scoActiveTopShadow
      172 186 204            scoAltBackground
      0   0   255            scoHighlight
      If you have problems starting a Resume session, ensure a link has been made between /usr/bin/xresume and /usr/local/xserver/bin/xresume
      (see the Help topic 'Configuring Vision Resume on UNIX' for more details).
    • If on starting a Resume session you see the error message "Cannot relocate your Resume session to that display" this may be caused by a network naming problem. Try displaying an X client from the UNIX host that you run the proxy server on to your Vision X Server, using the X Server's full DNS name (for example, xclock -display myPC.myCO.co.uk:0). If this reports "Cannot open Display" then you have a naming problem—try adding the full DNS name to /etc/hosts.


  • Multiuser Windows environments.
    • MKS 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.


  • MKS X/Server 3D.
    • Restrictions
      • Backing store shouldn't be used with the GLX extension.
      • OpenGL extensions are not available.
    • Notes
      • The GLX extension is disabled by default. The GLX extension can be re-enabled using the MKS X/Server Configuration program.
      • On true color displays, GLX color index visuals are only available using the Pseudo Color default visual class.
      • 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.
