I am a newable ubuntu user about a month ago.

My maschine'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 reduse the brightness of my screen i saw a link for bumblebee https://wiki.ubuntu.com/Bumblebee#Installation and i realised 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 recomended.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

etc/modprobe.d/nvidia-graphics-drivers.conf 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 undersand why Nvidia is blacklisted and why if i reinstall drivers it doesen'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!
