Running "blender-softwaregl --factory-startup" also crashes exactly the same way.

Exact steps for others to reproduce the error

Run "blender" or "blender-softwaregl --factory-startup" in terminal.

Disabling OpenGL and Composite extensions in CompizConfig Settings Manager had no effect.

What is your output from:

$ glxinfo | grep -i opengl
$ glxinfo | grep GLX_ARB

If you do not see the "GLX_ARB_create_context" in the grep command, then your GPU driver does not support the needed functionality to run blender.
It says here that the intel i965 driver should have that extension: https://mesamatrix.net/

lshw -c video shows my system is using i915.

I think you are using software rendering (so you are not using you GPU to render).
The vendor string and renderer string implies as much. And that is why you are locked to opengl 2.1.

Blender 2.8 requires at least opengl 3.3. So you will have to figure out how to get the intel drivers working properly.
This is not a blender problem though.
