I tried starting XBMC and an information window appeared saying:

     XBMC needs hardware accelerated OpenGL rendering.
     Install an appropriate graphics driver.

this suggests I uninstalled the driver because it WAS working. how did that
happen? what
should I install?  I thought perhaps 'apt-get install opengl' but the
repository includes only opengl-4.2-html-doc and opengl-4.2-man-doc
which seems to be the documentation.

An inquiring mind wants to know.
