That's a known issue; the nvidia module name has been changed in
Debian as of 319.32-2 (if I remember correctly). Also see .

That's intended; primus enables vblank synchronization by default
(i.e. FPS will not go beyond monitor refresh rate). If, for some

vblank_mode=0 in your environment, e.g. try running
$ vblank_mode=0 optirun glxgears
