Renaming those files disables the Object Graphics hardware-accelerated
rendering path. You are not using OG by running the TV command, but I
guess that the drivers are getting loaded anyway somehow.

Anyway, in Linux, those gl_driver.so libraries use whatever OpenGL
libraries and drivers are installed on your Ubuntu installation. The
error message suggests a problem with drivers associated with the
OpenGL libraries. Therefore, the problem may be outside of IDL and in
the graphics drivers installed in the OS.

One direction, which should have been suggested by ITTVIS support,
would be to check out your OpenGL drivers with other applications.
Try running glxgears, which is shipped in that distro. Glxgears is a
simple test program that can be used to see if the OpenGL libs are
basically working. Might try googling around for any known problems
with OpenGL on your particular distro and hardware (graphics
adapter). Look for any driver updates from the graphics card vendor
and/or use the Ubuntu package manager to install alternate drivers.
