Public bug reported: When I remove bumblebee from my system and reboot Unity refuses to start. Lightdm works as expected. Reinstalling bumblebee through a shell (and rebooting) makes everything work again. The strange thing is that bumblebee did NOT work when I removed it, so I couldn't run software on the discrete GPU. This must mean that removing bumblebee removes some other essential package. After reinstalling bumblebee the discrete GPU now works.
--DISCLAIMER!! SOME PROFESSIONAL GUESSING IS ONGOING!-- ;-) Could the problem be that 'bbswitch-dkms' is removed but the integrated graphics not correctly configured? Or has this module no "power" over the integrated GPU? Just guessing here, I have no idea.
