V Ubuntu jsem mel podobny problem i s jednou nvidia grafikou, mohl za
to svobodny nouveau ovladac.
Vzdy mi pomohlo bootovat s "nomodeset".

Taky nemohu v BIOSu vypnout jednu grafiku. Mam notebook ASUS P53SJ

Pouzivam Ubuntu 12.10 a bumblebee, vse dela Intel grafika, jenom kdyz
spustim program pres optirun, pocita to nvidia, ale
vypocitana data kresli na monitor pres intel grafiku. S AC napajenim
to imho nema nic spolecneho
(mozna zalezi na nastaveni bumblebee):
