Nvidia 331 installed but unable to select it

[NoWorries]

Been away for a while. Now returning to this thread.

@NoWorries: Would you please run the two commands I requested in my post #11?

@Don: Installing the nVidia binary driver should create a blacklist file in /etc/modprobe.d. What's the output of
tail -n +1 /etc/modprobe.d/nvidia*

Welcome back and I am sorry to have missed your request. So here is my rather belated reply. The lspci -k output is:

Well, for some reason, even though you've installed the nVidia binary driver, it isn't getting loaded. You can tell because there's no "Kernel module in use" line underneath the nVidia controller in the output of lspci -k. This is confirmed in the output of lshw -- "UNCLAIMED" means no driver loaded, which you can verify by looking at the "configuration" line and not seeing a "driver=" entry.

I believe you may need to return to the original configuration you described in your initial post and simply remember to issue optirun whenever you want an application to use the nVidia graphics.

Out of curiousity, what does grep -i nv /var/log/syslog show?

I was hoping to avoid using bumblebee with optirun as I find this an untidy solution. I am currently testing 14.10 and waiting for it to improve so that I can install it on my Laptop. I hope that the nVidia solution with their driver is better. For the interim I will install bumblebee and use optirun for those applications that perform better with the nVidia driver.

Out of curiosity, what does grep -i nv /var/log/syslog show?

My syslog is as follows:

:~$

In this output, I cannot see anything related to the nVidia/Intel graphics. The NetworkManager information is related to the fact that I have both the Wireless and an Ethernet connection to my Laptop. I prefer the latter because it is faster.

I now realise that the fact that my hdmi connection does not give any output with 14.04 whereas it did, "kind off" for 13.10, is a separate issue and unrelated to the graphic drivers.

I have now installed Bumblebee and to my surprise is was in the repositories without having to add one for Bumblebee. I also installed primus and now start tasks with

vblank_mode=0 primusrun [B]Application[/B]

After a reboot and starting two applications using primusrun, my syslog now shows:

I gather that since bumblebeed cannot get the display DPI, I still have the nVidia driver operating with this application. I get identical output when I use either optirun or simply primusrun to start an application.

My output for sudo lshw -C display no longer shows the nVidia card, ie.

AFAIK:

Jul 2 18:55:52 basil bumblebeed[2565]: [XORG] (WW) NVIDIA(0): Unable to get display device for DPI computation

is expected if your HDMI port is connected to the Intel GPU or to nothing. The nvidia driver is saying that it can't derive DPI since no physical screen is connected (to the nVidia GPU).

What does sudo powertop show for GPU usage (TAB over to "Device Stats")? The output of xrandr -q might be interesting also.

AFAIK:
is expected if your HDMI port is connected to the Intel GPU or to nothing. The nvidia driver is saying that it can't derive DPI since no physical screen is connected (to the nVidia GPU).

When I saw this message, my laptop was connected to an LCD screen via a 15 pin VGA socket. My first response was to reboot with this screen disconnected. I got exactly the same message that it couldn't derive the DPI. I normally require the HDMI connection when I go out and need to show movies or pictures. My fall-back is to use the VGA option and because this works, it must be connected to both the Intel and the nVidia video output.

For the VGA connection the powertop output is:

So, for some reason unknown to me, the system is not seeing the HDMI connection.

Please let me know what other tests I should try to get the HDMI connection.

[oshunluvr]

So in the second test, was anything displayed on the HDMI screen?

Very strange that the nvidia card and the HDMI port sort of disappear when in use.

Have you read this page: https://github.com/Bumblebee-Project...-monitor-setup

Sorry, I don't have any new ideas at the moment.
