I know there are lot of posts with similar titles... but I think I've tried about all of them.

I can't seem to get nvidia drivers to work.

Failure mode. I go through the below steps... After rebooting... the system will seem to boot normally (even a glimpse of the ubuntu splash page).. but eventually... all output from my HDMI will cease.. and my TV will just say "no signal from HDMI"

System

Nvidia 760GTX
Samsung 46" TV as Monitor
Connected Via HDMI from video card to monitor.

Steps.

1. Clean install of ubuntu 14.04
2. apt-get update && apt-get upgrade -y
3. add-apt-repository ppa:graphics-drivers/ppa
4. apt-get update

from here it diverges.. first I tried

ubuntu-drivers autoinstall

and I would get the failure mode described above.

All subsequent attempts... I instead would do a...

ubuntu-drivers devices

and then 

sudo apt-get install nvidia-361

For this last step.. I started with the the 'recommended' driver listed here (364).. and then I tried the one nvidia recommends for the 760GTX on their website (361)... and then I tried all the rest...

Same failure mode.

Any ideas? I'm wondering if others might have some insight into the failure mode where the HDMI signal just seems to get lost.

Thanks!

  • you can read my article over here to understand a little bit more about nvidia drivers... I've been using nvidia official driver on Ubuntu for all the years using hdmi and on different nvidia videocards and no issues whatsoever. – JoKeR Apr 12 '16 at 09:48
  • I will give using the official drivers from their website a try and report back. – Deanconia Apr 12 '16 at 23:27

It seems difficult to figure out the issue from the problems you just described. Primarily, I suspect this could be nouveau issue. If you are installing Nvidia driver, then nouveau should be disabled.

One way you can do to disable nouveau is by adding nouveau.modeset=0 as kernel parameter :

# grubby --update-kernel=ALL --args=nouveau.modeset=0

and then reboot the system.

The GTX760 has a DVI-I output connector. Try connecting a DVI to VGA adaptor to it and then connect to a monitor using a VGA cable. If this works then you will be able to play with the different drivers. The article by JoKeR seems very comprehensive.

  • Hmm... but it also has HDMI (which is what I'm using while using the standard xorg drivers)... Are you thinking that the DVI -> VGA would work while the HDMI would not? – Deanconia Apr 12 '16 at 23:12
  • I think it is certainly worth a try since this is an analog output rather than digital. I am using a much older Nvidea card (GeForce 8600) and I had problems using the xorg (nouveau) driver. In my case it would sometimes boot correctly and sometimes boot to a black screen. Changing to the recommended Nvidea driver has made it much more reliable. – Steve Roome Apr 13 '16 at 09:17
