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:
- optimus = NVIDIA + INEL
- UMA = Intel only
Is there any idea?
