Harmony Fails to Open or Crashes on Startup on Linux

Periodically, Harmony does not open and displays an NVIDIA error message in the shell. This may not happen all the time. Users may report this error after running the application several times successfully.

The NVIDIA error message directs users to instructions in the Readme file:

/usr/share/doc/NVIDIA_GLX-1.0/README.txt

Problems with the security node of the PAM system can cause these periodic problems. Follow the instructions in the NVIDIA Readme to resolve this error.

If you continue to experience problems, verify that the xorg.conf file (in /etc/X11/) contains the correct driver information (the driver should be nvidia, not nv).

If this does not resolve the problem, reinstall your NVIDIA driver.
