[SOLVED] Nvidia gtx 660 driver not working on ubuntu 14.04

[Delliriumy]

The problem is with nvidia drivers. I battle for quite some time chasing my tail.

Details :

syslog warning :

"kernel : nvidia: module verification failed: signature and/or required key missing -tainting kernel"

Xorg.0.log :

"NVIDIA(1) : Setting mode "DFP-0:nvidia-auto-select"
"NVIDIA(GPU-0): Display (DELL U2410 (DFP-0) does not suppport NVIDIA 3D VISION"
"NVIDIA(GPU-0): stereo."

Xorg.1.log :

"(WW) Warning, couldn't open module nvidia"
"(EE) Failed to load module "nvidia" (module does not exists, 0)"

I can work in ctrl+shift terminals but ctrl+shift+f7 prompts black screen.

Are you installing this driver through Additional Drivers? It seems to me that this is the problem.


NVIDIA(GPU-0): Display (DELL U2410 (DFP-0) does not suppport NVIDIA 3D VISION"

What driver is this?

What do you mean by additional drivers? I tried to install from suggested repositories and didn't work at all. Now i installed directly from nvidia drivers webpage for linux.

And it have some problems with U2410m which is LCD DELL display?

Problem solved...i think. It all came down to regenerate xorg.conf and restart few times lightdm then restart pc.
