      On a Ubuntu 12.04 system (see environment tab) I downloaded and installed qt-linux-opensource-5.2.0-x86_64-offline.run - ran as root and installed into /opt/Qt5.2.0.

      After ssh'ing into this machine from Windows 7 desktop, I try and fire up qtcreator to remote display back to Cygwin X11 server running on my desktop, and it segfaults:

      user@colossus:~$ /opt/Qt5.2.0/Tools/QtCreator/bin/qtcreator
      Xlib: extension "NV-GLX" missing on display "localhost:10.0".

      I was going to attach the core file but it's 20MB compressed with xz, so I can't.

      Linux system does have Nvidia binary graphics driver installed. Local Windows system (Cygwin X11 Server) is using AMD Graphics.

      Other apps, such as glxgears, glxdemo, emacs, gedit, etc, operate properly via remote display.
