After a few sleep cycles, I sorted out the problems.
Here are the notes I've made for the future :

  NVidia vs Nouveau : 

  NVidia : (1) use non-Nouveau kernel ;
           (2) emerge with 'linux' symlink pointing to current kernel ;
           (3) 'nvidia-eg.conf' must be in  /etc/X11/xorg.conf.d/  cont :

               Section "Device"
                 Identifier  "Device0"
                 Driver      "nvidia"
                 Option      "TripleBuffer"     "True"
                 Option      "NoLogo"           "True"
                 Option      "DynamicTwinView"  "False"
               EndSection

           (4) 'eselect opengl set nvidia'.

  Nouveau : (1) 'emerge xf86-video-nouveau' ;
            (2) use Nouveau kernel :

                  Driver -> Graphics -> <*>DirectRenderingMgr [Y]
                                        <*>NouveauCards [Y] ;
                                        
            (3) move 'nvidia-eg.conf' out of  /etc/X11/xorg.conf.d/ ;
            (4) add '10nouveau.conf' to  /etc/X11/xorg.conf.d/  containing :

                Section "Device"
                  Identifier  "Card0"
                  Driver      "nouveau"
                EndSection ;
             
            (5) 'eselect opengl set xorg-x11'.

HTH others.
