If you install bumblebee but dont install the nVidia closed drivers, 'optirun XXXX' would probably use nouveau. Try ruuning 'optirun glxinfo | grep OpenGL' and you will probably get the nouveau readout.
If there is a difference between a 12.04 install and a post 2012-06-01 install (or updated) then the differnce is probably due to updates (there was some odd bugs in 12.04 including some related to graphics, maybe canonical has finally fixed some of them)
Thanks cascade9: Im late reading this msg since i must boot to lucyd my primary Dist not to precise(expiremental) to read this msg. before i read this msg i already install bumblebee and some odd observation i determine:
1. Nouveau module not loaded in default not like before i install bumblebee which is loaded by default.
2. glxinfo without optirun show something like what you said on "OpenGL vendor string: Tungsten Graphics, Inc, etc"
3. But google-earth run on intel (without optirun)
4. Using optirun, runnning some glx* show nvidia card info or simple nvidia card is now working.
5. Using optirun, nvidia module loaded "maybe your wrong on running optirun but using the nouveau driver and not the nvidia driver"
What i would like to know is if nouveau module is loaded by not using bumblebee then maybe my current 12.04 updated since 2012-06-03 using nouveau driver is using the nvidia card..
Maybe i will try to remove bumblebee and try the glxinfo command with nouveou module loaded, i missed this procedure to determine what graphics card are using before i installed bumblebee. Ive just confused since the nouveau is loaded and its purpose is for nvidia card right.
