Windows-Specific Release notes for X2Go Client

Major Windows-specific changes since

This is a 4th-decimal-place minor release of x2goclient. Therefore, major changes are supposed to be few in number, and are only implemented when they are low risk.

Smaller Installer

The size of the NSIS installer has been reduced from about 21MB to about 16MB by switching to lzma solid compression


nxproxy (nx-libs-lite) now uses cygwin's libjpeg-turbo, instead of cygwin's libjpeg. This reduces the CPU usage of nxproxy.

Available Builds

All builds with version “” in their filename are current.

Corresponding server versions of Windows are also supported, but receive minimal testing:

  • Windows Server 2003 SP2

Installation Instructions

Windows-Specific Bug Fixes

As mentioned in the regular release notes:

  • Fix starting sshd on Win XP. (Fixes: #421)
  • Fix “fullscreen” mode on Windows 7 with multiple monitors.
  • Prevent high PulseAudio CPU usage on Windows XP by lowering PulseAudio's CPU priority from “high” to “normal” on XP specifically. Also do so on Windows Server 2003 (R2) (Fixes #526)
  • Enable PulseAudio log when –debug is passed. (Technically not a bugfix, but it is a minor enhancement which helps users and developers debug X2Go Client.)
  • nxproxy (nx-libs-lite) was downloaded and compiled from the release tarball, rather than from git, so that the patches are actually applied. (This may fix multiple nx-libs bugs in X2Go Client for Windows.)
  • Switch from regular NSIS 2.46 to Unicode NSIS 2.46.5 (Fixes: #528)

Noteworthy Windows-Specific Bugs

  • bug 108 - Certain legacy applications fail to start (or exhibit font-related bugs) due to the fonts not being installed on the X2Go Client. This can be worked around by using the x2goclient- installer located here: . If the problem still persists, try using x2goclient- instead.
  • bug 109 - x2goclient refuses to start after selecting a nonexistent external X server. To prevent this bug, do not select to use an external X server without specifying the path to an external X server that is actually installed. (The default path usually does not exist.) If you are experiencing this bug, work around it by setting this registry value: HKEY_CURRENT_USER\Software\Obviously Nice\x2goclient\settings\useintx = true
