Updating NVIDIA Graphics Driver in Linux (Ubuntu 14.04)<\/p>\n
If you have been playing with NVIDIA graphics installs then deactivate the driver from the Additional Drivers window and then reactivate to reinstall.<\/p>\n
You can also remove all references to nvidia kernels install via<\/p>\n
\nsudo apt-get remove nvidia*\r\n<\/code><\/pre>\nsudo apt-get remove --purge nvidia-*\r\n<\/code><\/pre>\nThen installing\u00a0
nvidia-current<\/code>:<\/p>\nsudo apt-get install nvdia-current<\/code><\/pre>\n<\/blockquote>\nThen reinstall the driver from Additional Drivers window.<\/p>\n
Install nvidia-331. I did it through Synaptic Package Manager.<\/p>\n
sudo apt-get install nvidia-331<\/code><\/pre>\n<\/p>\n
Additionally run the Nvidia routine to generate a new xorg.conf<\/p>\n
\ngksudo nvidia-settings<\/code><\/pre>\n<\/blockquote>\n<\/p>\n
To stop your display manager or the X server, you can type in the console this code:<\/p>\n
sudo stop lightdm or\r\n\r\n sudo lightdm stop\r\n<\/code><\/pre>\nIf you are not using\u00a0lightdm<\/strong>\u00a0as your default display manager (DM), replace lightdm with your default display manager, which can be either\u00a0kdm<\/strong>\u00a0or\u00a0gdm<\/strong>\u00a0or whatever your display manager is.<\/p>\n
You should get a message in the terminal console saying –> lightdm stopped\/waiting<\/p>\n
And now you can finally install the nvidia driver using a code similar to this one:<\/p>\n
sudo sh NVIDIA-Linux-x86_64.....run (for Ubuntu 64bit) \r\n<\/code><\/pre>\nor<\/p>\n
sudo sh NVIDIA-Linux-x86.....run (for Ubuntu 32bit)\r\n<\/code><\/pre>\nIf you don’t type the exact name of the driver, you’ll get this message:\u00a0NVIDIA-Linux… could not be found<\/strong>\u00a0and you should type again the code for installing the driver.<\/p>\n
Nvidia installer automatically installs the driver, and at the end it will ask you whether you want to save your new X configuration. Press Yes. After reboot and getting to your desktop and changing your NVIDIA settings as you please you should open a terminal window and type in this code:<\/p>\n
sudo nvidia-xconfig\r\n<\/code><\/pre>\nsudo apt-get install nvidia-settings<\/pre>\nto save your new nvidia configuration in \/etc\/X11\/xorg.conf.<\/p>\n
It can happen that after reboot your system shows a black screen or enters the low graphics mode. To fix this you should exit again to the console terminal, login with your username and password, and use the code provided above\u00a0sudo nvidia-xconfig<\/strong>\u00a0and also make use of the following tutorial. It is meant to\u00a0fix the greeter<\/a>\u00a0assuming that they haven’t fixed this bug in Ubuntu 14.04.<\/p>\n
