*Rats* !!!! I had an old Linux box where VESA did provide (gruesomely 
slow) OpenGL software rendering, but that was eons ago. All of my 
desktop (XFCE 4.12) works AOK, ditto for browser, etc., although many of 
the screensavers crash w/ messages about .... GLX extension not enabled 
:-/ .... Oh well ....
