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 > -----Original Message----- > From: [email protected] > Sent: Sat, 16 Jul 2011 17:48:18 -0300 > To: [email protected] > Subject: Re: [Hybrid-graphics-linux] Bumblebee test on PCI ID: 10de:0a75 > > Vga switcheroo reports that can handle the card.
