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
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
