Well, after updating bumblebee my system reached the "leave me alone please!" state, so I uninstalled bumblebee, nvidia-current, etc.
One of the main issues was that it was trying to boot with the nouveau driver, apparently, and the following message appears:

[drm] nouveau 0000:01:00.0: LVDS present in DCB table, but couldn't determine its native mode. Disabling.

After that I saw some scary messages such as "soft lockup on cpu#2 for 61s!", the system got unusable.

Luckily, I was able to enter in recovery mode, and managed to reinstall libgl1-mesa-dri & -glx, uninstall bumblebee and (fingers-crossed) it is working as usual, except for turning off the nvidia card, it doesn't work now:

insmod: error inserting 'acpi_call.ko': -1 Invalid module format

but at least I can use my notebook. VGA-switcheroo is enabled but echo OFF says Permission denied (even with sudo).

$ cat /sys/kernel/debug/vgaswitcheroo/switch
0:+:Pwr:0000:00:02.0
1: :Pwr:0000:01:00.0
