i have recently installed Ubuntu 12.04 in a Intel Ivy Bridge with integrated graphics and NVidia GPU with Optimus tech, however i cant manage it to work properly. I have already passed by the solution of bumblebee project, however iam got the following message when try to run anything with nvidia card( e.g. with
[ERROR]The Bumblebee daemon has not been started yet or the socket path /var/run/bumblebee.socket was incorrect. [ERROR]Could not connect to bumblebee daemon - is it running?
Since the nvidia card is not working properly, some softwares like Scilab, that make use of X11 system for graphic handling and plotting, wont work too.
my bios has no option concerning graphics card and the log of daemon returned:
Jul 5 16:10:51 humannoise-W251ESQ-W270ESQ bumblebeed: Module 'nvidia' is not found. Jul 5 16:10:51 humannoise-W251ESQ-W270ESQ kernel: [ 17.943272] init: bumblebeed main process (980) terminated with status 1 Jul 5 16:10:51 humannoise-W251ESQ-W270ESQ kernel: [ 17.943288] init: bumblebeed main process ended, respawning Jul 5 16:10:51 humannoise-W251ESQ-W270ESQ bumblebeed: Module 'nvidia' is not found.
lspci -nn | grep '\[030\]:' returned:

Ok, for the command
dpkg -l | grep '^ii' | grep nvidia i got :
ii bumblebee-nvidia 3.0-2~preciseppa1 nVidia Optimus support using the proprietary NVIDIA driver ii nvidia-current 302.17-0ubuntu1~precise~xup1 NVIDIA binary Xorg driver, kernel module and VDPAU library ii nvidia-current-updates 295.49-0ubuntu0.1 NVIDIA binary Xorg driver, kernel module and VDPAU library ii nvidia-settings 302.17-0ubuntu1~precise~xup3 Tool of configuring the NVIDIA graphics driver ii nvidia-settings-updates 295.33-0ubuntu1 Tool of configuring the NVIDIA graphics driver
After full reinstallation, including the remove of any previous nvidia drive,
lsmod | grep -E 'nvidia|nouveau' returned:
nvidia 10888310 46
dmesg | grep -C3 -E 'nouveau|NVRM' returned things like:

Some programs, like Scilab, are now working fine under optirun(e.g.
>optirun scilab) call.
