Nvidia Graphics Debugger does not work with packaged drivers

[Giuseppe D'Angelo]

Launching any application in the Nvidia Linux Graphics Debugger does not work with the Ubuntu packaged drivers, but it works by manually installing the Nvidia upstream drivers (same version). A packaging issue is the likely issue of this.

Steps to reproduce:

1) install LGD from https://developer.nvidia.com/linux-graphics-debugger
2) launch it, against x64, connect to localhost, click on the Launch tab and click on the "Install debugger" button
3) try to launch any OpenGL application under LD_PRELOAD=~/.tgd/libs/libNvidia_gfx_debugger.so . For instance:

$ LD_PRELOAD=~/.tgd/libs/libNvidia_gfx_debugger.so glxgears
LGD: Starting GTI initialization...
LGD: GLX vendor: NVIDIA Corporation
LGD: Graphics interception initialized
Xlib: extension "NV-GLX" missing on display ":0".
Error: glXCreateContext failed
Segmentation fault (core dumped)
