There are hybrid machines which have both Intel and NVidia GPUs. Depending on a switch position, you may activate one of the GPU. Usually, on-CPU GPU gives power efficiency, while discrete one provdes a performance.
For such machines, it is _very_ useful to have both libGL.so.1 installed and somehow switched around. It would be best to have Mesa and NVidia libGL.so.1 installed under other names, like libGL-mesa.so.1. and ligGL-nvidia.so.1, and provide a symlink for libGL.so.1 BTW, besides libGL.so.1, another conflicting file is /usr/local/lib/xorg/modules/extensions/libglx.so.
