Identification

this command 

lspci | grep VGA

more detailed w/o root 

lspci -vnn | grep VGA -A 12

more detailed (requires sudo root) - this actually shows the driver being used. 

sudo lshw -C video

OpenGL

Determine OpenGL version 

glxinfo | grep "OpenGL version"

glxgears is a simple utility to test 3D Acceleration 

sudo apt install mesa-utils
glxgears

Why mesa-utils and what is mesa? Mesa is an open-source implementation of the OpenGL. The OpenGL libGL.so comes with your driver.

What is your video card 

lspci
lspci|grep -i vga

To upgrade to a newer version of OpenGL you will have to update the graphic card driver. The graphics chip AND corresponding driver will provide higher possible OpenGL support.

You may not have the option to upgrade to a newer graphics driver. For example the Radeon HD 7560D can not be updated with a new driver other than one the distribution includes in the kernel. Radeon HD 7560D is not supported by amdgpu because it is not GCN hardware, it is supported only by the radeon driver.
