uninstalling bumblebee leaves unusable system

[Paul Greindl]

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.

Status changed to 'Confirmed' because the bug affects multiple users.

After removing, the kernel will not load nvidia nor nouveau for an nvidia graphics card. The only fix seems to be re-installing ubuntu.

[korst (jasperkorst)]

can it be ta this is because /etc/modprobe.d/bumblebee.conf is still left behind? (this file blacklists nvidia drivers) http://askubuntu.com/a/403329/154126

[Paul Greindl (paul-greindl)]

Could be... Anyway I think if you remove bumblebee, which has the nvidia driver as a dependency, the integrated graphics should be activated. I guess it's somewhere here something goes wrong.

File /etc/modprobe.d/bumblebee.conf still remains in the system after removing bumblebee - 3.2.1-7 on Ubuntu 15.04

[Vincent Cheng (vincent-c)]

Fixed (for real) in bumblebee/3.2.1-11, sorry for the bogus attempt in -6.
