if you have set an xorg.conf, then remove it :


sudo rm /etc/X11/xorg.conf

that issue is frequent with nvidia, purge it:


sudo apt-get purge nvidia*

and reinstall the genuine nvidia-current package (if you have installed/activated some ppa, then deactive them first and reupload again)


sudo apt-get install nvidia-current

then logout/in to know if that makes a difference.

Hi!, xinbye,

After you installed the NVIDIA.com driver you Posted: "it't fail", What does this mean?

The nvidia installer.log shows a successful installation. So what in fact happened.?

If you followed dino99's code you will have installed 295.40 which is bug-ridden.

Have you tried deactivating either the Integrated graphics or the nvidia card from Bios.? If not, please try both and Post the results..

According to Nvidia, your system cannot work unless that facility is available.

For those with Integrated Graphics: Extract from Nvidia's "Supported Products" notes:".... in particular, notebook and all-in-one desktop designs with switchable (hybrid) or Optimus graphics will not work if means to disable the integrated graphics in hardware are not available. ...".If , before you try that, and in both selections, you run nvidia-settings or Nvidia Xserver Settings does it show the nvidia driver in use and can you reset the resolution ?

Please Post the output from:
lspci -nnk | grep -iA3 vga
sudo apt-cache policy nvidia-current
cat /sys/module/nvidia/version
/usr/lib/nux/unity_support_test -p Copy/Paste the info to a New Reply edit box, highlight it and press the '#' symbol in the toolbar, to put it in Code boxes for easy reading.

The first command will show what drivers & modules are in use; [ with a lot more detail than your VGA attachement.]
The second will show details of the nvidia-current drivers available and if installed, which.
The third, if you do not have a nvidia.com driver installation will return 'not found' or 'no such'.

Chao!, bogan.

Hi!, xinbye,

What I meant by:" what does 'it't' mean ?", was: " In what way does what fail?:

The installation? The driver?, The display?, The command or The computer? - and HOW?

In other words: What are the symptoms of the fault you need help with? Is it just that you only get Low-Res screens?

Your Post shows you have both the nvidia.com 295.40 driver installed, and the Ubuntu 295.40 nvidia-current driver, at the same time. This will inevitably cause conflicts.

You should choose one or the other, or a later version instead.

If you copy/paste: " /usr/lib/nux/unity_support_test -p ", into a terminal, and press 'Enter', it will run that script, & it should show which OpenGL, and hence which driver is actually effective, and if unity 3d is fully supported.

I have no idea why you get a request for '-help' with 'nvidia-settings'. Try 'gksu nvidia-settings'. if that does not work run:
sudo apt-get update
sudo apt-get install nvidia-settingsfirst and re-run nvidia-settings.

Chao!, bogan.

Hi!, xinbye,

You Posted:
how do i choose ?You decide which driver you want to use, remove both the existing versions, and either use the default nouveau driver, or install the one you want to use.

Try both ways and see which is best. I would recommend not using the 295.40 nvidia-current as it is bugged. Rather, if you want to use an nvidia-current driver, use the post -release updates version offered in Additional Drivers, or the x-swat ppa 304.43 version.

I just do not know what causes the " it not run and request "-- help" " message, please post the actual message.
If you make a typo in entering the code you should get a message saying command not known or not found and suggesting you run --help with the command which will list the options. Is that what you did?

In fact you should run 'nvidia-settings' from root. ie use
gksu nvidia-settings but try: 'nvidia-settings --vv' You should get something like:
$ nvidia-settings --vv

Hi!, xinbye,

Reviewing the earlier Posts, I see that trying to install 'nvidia-settings' got a message that it was already the latest version, so perhaps, if it is not running, it is corrupted, & that is one problem's cause.

So run:
sudo apt-get install --reinstall nvidia-settingsWhen it is properly installed you should also be able to use it via 'Dash'.

Click on the Ubuntu 'Dash' Icon, and type 'nv', it should display an Icon with the Nvidia logo, entitled " NVIDIA X Server Settings" clicking on which runs the same program as 'gksu nvidia-settings' does from a terminal.

I also see that the same report notes that there are 72 packages that need updating. You really should update regularly; there is probably a kernal update included in that list.

Chao!, bogan.

Open and edit xorg.conf like this: sudo nano /etc/X11/xorg.conf.

Find the line that says: Section "Screen"

Insert a new line that says Option "UseDisplayDevice" "DFP".
and


sudo gedit /etc/modprobe.d/blacklist.conf


blacklist vga16fb
blacklist rivafb
blacklist rivatv
blacklist nouveau
blacklist lbm-nouveau

Hi!, xinbye,

Did you run 'nvidia-settings', without the '--vv'??

At what stage do you get the blank screen ?

Do you get a grub menu? a login screen ? Can you login ?

Can you boot via Recovery if you get the grub menu ?

At the blank screen, [ or at login screen ] do you get a terminal login prompt if you press: 'Crtl+Alt+F1' ??

[If you do, to return to the GUI{?} mode, press: 'Crtl+Alt+F7'].

If you can get to a terminal, please re-post:
lspci -nnk | grep -iA3 vga
sudo apt-cache policy nvidia-current
cat /sys/module/nvidia/version
/usr/lib/nux/unity_support_test -pChao!, bogan.

Hi!, xinbye,

We do not seem to be getting very far, do we?

How are you getting to a Terminal?

Please run
gksu nvidia-settings and Post the results. Do you get a "Error: unable to open display" message? { that is without the '--vv', which only tells what version is installed, and does not run the configuration program}.

Re-reading all the Posts, I do not see anything to say you tried the suggestion in my Post #4:

Have you tried deactivating either the Integrated graphics or the nvidia card from Bios.? If not, please try both and Post the results..

According to Nvidia, your system cannot work unless that facility is available.
For those with Integrated Graphics: Extract from Nvidia's "Supported Products" notes:".... in particular, notebook and all-in-one desktop designs with switchable (hybrid) or Optimus graphics will not work if means to disable the integrated graphics in hardware are not available. ...". One thing you could try, with the hybrid Intel graphics working, is to edit the Grub menu Script [ press 'e' with Ubuntu highlighted ] and add to the Linux Boot line: "video=1280x1024-24@60" {without quotes}, & press 'Crt+x' to boot.

It is reported that this can force the recognition of the Intel i915 driver. I know this is not what you want, and I do not know if it will work with a conflict with the nvidia driver, but it might show us something. If necessary, change the figures to those of your Monitor's native resolution.

Chao!, bogan.
