I am a newable ubuntu user about a month ago.

My machine's specs are:

Linux lenovo-Ideapad-Z570 3.11.0-19-generic #33~precise1-Ubuntu SMP Wed Mar 12 21:16:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

And I'm using

Ubuntu 12.04.4 LTS

After a lot of experiments to my vga card to reduce the brightness of my screen I saw a link for bumblebee and I realized that I can fix my laptop's energy problem also.
But after the installation my ubuntu the only thing that give me is a system running in low-graphic mode.

After a lot of research I found the way to login in low res by getting in recovery menu, failsafeX, Reconf graphics, reboot and resume.

So what I have now is that my laptop can recognize the VESA:Intel®Sandybridge Mobile Graphics and not my NVIDIA GPU.

So I went to system settings -> Additional drivers and install the driver that was recommended. Reboot, but the same thing. The driver was active but not in use!!!!

So after this I've done sudo fgrep nvidia * | fgrep blacklist and I found that my NVIDIA was blacklisted!!!

I uninstalled bumblebee

$ sudo apt-get remove bumblebee
$ sudo rm bumblebee.conf

and install again Nvidia drivers but nothing again

I've tried to do this


But I had a command not found.

So I have only this now:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 540M] (rev ff)

I can't understand why Nvidia is blacklisted and why if I reinstall drivers it doesn't work.

Something more is that in bios there are only two options:

  1. optimus = NVIDIA + INEL
  2. UMA = Intel only

nothing works.

Is there any idea?

Thank you


It's not the best help, but I'm experiencing a lot of problems trying to install nvidia drivers for my GT740M. While Geforce.com informs to us that driver 331.20 supports GT740M, by executing "grep -FN 'NVRM:' /var/log/kern.log", I can see:

52044:Apr 11 13:24:13 NAUTILUS kernel: [ 3270.758568] NVRM: The NVIDIA GPU 0000:0a:00.0 (PCI ID: 10de:1292) 52045:Apr 11 13:24:13 NAUTILUS kernel: [ 3270.758568] NVRM: Installed in this system is not supported by the 331.20 52046:Apr 11 13:24:13 NAUTILUS kernel: [ 3270.758568] NVRM: NVIDIA Linux driver release. Please see 'Appendix 52047:Apr 11 13:24:13 NAUTILUS kernel: [ 3270.758568] NVRM: A - Supported NVIDIA GPU Products' in this release's 52048:Apr 11 13:24:13 NAUTILUS kernel: [ 3270.758568] NVRM: README, available on the Linux driver download page 52049:Apr 11 13:24:13 NAUTILUS kernel: [ 3270.758568] NVRM: at www.nvidia.com. 52051:Apr 11 13:24:13 NAUTILUS kernel: [ 3270.759140] NVRM: The NVIDIA probe routine failed for 1 device(s). 52052:Apr 11 13:24:13 NAUTILUS kernel: [ 3270.759143] NVRM: None of the NVIDIA graphics adapters were initialized! 52054:Apr 11 13:24:13 NAUTILUS kernel: [ 3270.759222] NVRM: NVIDIA init module failed!

Also, their 331.67 driver does not recognise my GPU (supposedly compatible with this driver, too!). I wrote to geforce.com commenting my problems. We'll see.

my original post, commands used, etc, in:

Ubuntu 12.04 Bumblebee vs Nvidia GeForce GT 740M

Best wishes! and Good Luck!
