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.
