nvidia-detector "none"

[Ema0404]

Hi all,
I installed linux mint 14. I have an Acer Aspire 5755G with a nVidia GeForce GT 540M. I tried to install manually the linux drivers but the console said that the video card wasn't detected, infact typing

Code: Select all

nvidia-detector

the output is

Code: Select all

none

What does this mean?

before going any further with any driver installation, open a terminal and share with us the output of

Code: Select all

inxi -SGx

that is an optimus enabled technology card and driver installation can't be done the usual way

Adding ubuntu-x-swat and an update/upgrade/reboot may help solve your problem

what is ubuntu-x-swat? and what should I do for add it?

However I installed nvidia drivers (downloaded from the nvidia's official site), even if it said that drivers don't work. Not a good idea: my resolution was 640x480. I correct it editing xorg-conf like this:

user@host ~ $ cat /etc/X11/xorg.conf

and it seems to work.

it is useless in the gpu configuration you have.

I correct it editing xorg-conf like this:

this was a smart trick but i believe that it didn't addressed the main issue

GLX Renderer: N/A GLX Version: N/A Direct Rendering: N/A

< this one: according to this output you have no direct rendering (no 3d acceleration) furthermore you can't use the nvidia card in a per-app basis like you could with bumblebee https://wiki.ubuntu.com/Bumblebee
(now a warning note: bumblebee doesn't like to be installed when it detects traces of other nvidia drivers installations; it will fail)

[Ema0404]

I have already installed bumblebee but it doesn't work. Infact when I tried to configure nvidia settings with "optirun" the program didn't see nvidia card. Now, it doesn't like nvidia drivers (maybe). This is the output

Code: Select all

user@host ~ $ optirun nvidia-settings
