Nvidia graphics card driver installed led to login loop

  • 772

I am using Ubuntu 15.10 Desktop - 64 bit version on intel Core I7 - quad core laptop with 16 GB RAM, 4 GB Graphics card(Nvidia GTX 950M). After successful install - Ubuntu was freezing due to inbuilt and default graphics driver from Ubuntu is not good enough. I went ahead and installed "Nividia GTX 950 M driver" from http://www.nvidia.com/Download/driverResults.aspx/84043/en-us

and followed this link How do I install the Nvidia driver for a GeForce GT 630

Successful install of Nvidia graphics card but I end up with login loop at the time of login(unity and lightdm).

Here are some of my files from /var/log/ syslog

Nvidia installer logs seems to be okay too. What could be the problem? The password is working fine when i use Ctrl+Alt+F1 and then login to the terminal.

Here is the last few lines of nvidia installer logs

    Generally you should use the drivers from the official Ubuntu repositories.

    Because you are having problems, using the latest drivers might be better. Install the latest official stable NVIDIA drivers for the GEFORCE GTX 950M.

    First uninstall the currently installed NVIDIA drivers. Boot the computer, when the GRUB menu appears ...

    Highlight the Ubuntu menu entry and press the E key. Add nouveau.modeset=0 to the end of the linux line. Press F10 to boot the Ubuntu operating system.

    When the login screen appears press Ctrl+Alt+F1. Enter your user name and the password, then execute :

    sudo apt-get purge nvidia*  
sudo reboot

    Now install the latest official stable NVIDIA drivers. Boot the computer, when the GRUB menu appears ...

    Highlight the Ubuntu menu entry and press the E key. Add nouveau.modeset=0 to the end of the linux line. Press F10 to boot the Ubuntu operating system.

    When the login screen appears press Ctrl+Alt+F1.
    Enter your user name and the password, then execute : 

    sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-358 nvidia-prime
sudo reboot

    Note:

    Maybe it is explicitly necessary to select the NVIDIA adapter in BIOS. When you want to use drivers 352, adding the PPA is not necessary. In this case the terminal commands you have to perform are these: 

    sudo apt-get update
sudo apt-get install nvidia-352 nvidia-prime
sudo reboot

  2. enter image description hereThanks cl-netbox to some extent I am able to resolve the issue. This is what i have done

    sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-358
sudo reboot

    Please make sure that if you went to the nividia website and installed the driver from there(N*.run) - you must un-install this by going to /usr/bin/nvidia-installer. There should be something like nvidia-install(link to uninstall). Run that one and follow all the instructions. You should install the nvidia drivers from the ppa repository after cleaning up(purging the previous nvidia install). There is a bug in ubuntu and any time there is any issue in terms of installing the nvidia driver - you will end up with login loop.

    I am out of the login loop issue. The only issue that i am facing now is that once i login into Unity desktop-i am not seeing sidebar...(resolution issue)-terminal etc....are not having the title bar etc....so it seems some more steps are needed to fix the entire set. But yes I am out of that irritating login loop issue now.

    Next update - I was missing the sidebar via which i can launch applications and that got fixed via: Was able to get rid of the unity desktop issue also finally. I was able to do Right click and open the terminal. Tried many solutions as mentioned in this thread as well as others. Finally this worked for me.

    dconf reset -f /org/compiz/

    then

    setsid unity

    Everything seems to be working fine now. Thanks everybody

  3. A simple solution for me is, make sure your cable is plugged into the graphic card instead of the motherboard. IF you plug it into the motherboard, I am guessing ubuntu get confused somewehere.

    I have been dealing this problem for so long and finally this works for me. Thanks god.

    I just plug it into the GPU and reboot. problem solved.

    I have nvr thought about using the GPU for display because I am writing CUDA program and I dun really need the graphics from the graphic card.

    I also have to edit grub - remove gtfxmode line on line3/4 - add nomodeset noquiet and nosplash
