Try to configure vsync for multiple options. 

When we have a notebook with intel+nvidia, OpenGL sets both
`glXSwapIntervalSGI` (nvidia) and `glXSwapIntervalMESA` (intel) for
usage. That means that if the display is controlled by one, we may
disable vsync for the other card, therefore having no actual effect
on gameplay. With this, we check for all available functions and try
them all.

This may lead to some false warnings, but useful for debugging
purposes.
