Trying to install Nvidia .run drivers to Ubuntu 14.04 LTS desktop version
But X server is up and has a lock to prevent concurent installations.
I think I should switch in mode 1 or so to shut off X11 but I cannot manage to do so ...
Having read lots of documentation saying switch to console mode Ctrl-Alt-F1, ... , but when I kill X11 process, it re-starts automaticaly, whith no end
You can install accelerated Nvidia driver xserver-xorg-video-nouveau from main repo:
sudo apt-get install xserver-xorg-video-nouveau
You have to stop the Display Manager. As far as I understand then different distributions there own Display Manager. On Kubuntu as I am running it's called Lightdm.
To stop it go to console mode Login using your user name and password.
Stop the lightdm service by:
$> sudo service stop lightdm
Install the Nvidia driver and start the lightdm service by
$> sudo service stop lightdm
I can't recommend install NVidia's own driver from there web site as I haven't had very good experience with the driver. Instead go to the system settings and install the latest driver using the Additional Drivers app.
