cant install nvidia-linux-x86_64-340.46.run

hi there, i am pretty new to linux. and sorry for my bad english.
i am unable to to install the newest geforce drivers on linux.
i am using a lenovo ideacentre b5, with a geforce gt555, and zorin8 linux (based on ubuntu 1x.xx dont know)
try to execute the .run - doesnt work, want root.
so i did with sudo -i
the .run runs
then i get “ERROR: You appear to be running an X server; please exit X before
installing. For further details, please see the section INSTALLING
THE NVIDIA DRIVER in the README available on the Linux driver
download page at www.nvidia.com.”
BUT THERE IS NO README!!!

so, i exit the x server with ctrl+alt+f1…right?
root…
try to run the .run again…
get the same error about the x server?!
ehm help?

hey nvidia people, please make a simply execute able file for linux drivers! allright?
thx.

edit: zorin8, 64bit, based on ubuntu 13.10 - if it helps
nvidia-installer.log (861 Bytes)

the readme is here: http://us.download.nvidia.com/XFree86/Linux-x86/340.46/README/index.html

And the error pretty clearly states what you have to do: “please exit X before installing”
If you don’t know how to do that (or how to figure that out on your own), you should not mess around with the nvidia installer but just stick to the driver packages provided by your distribution!
It you feel lucky (have fun getting your broken system to graphical mode again if you don’t even know how to exit X) you should remove any distribution provided nvidia driver components before and disable the nouveau kernel module.
The cleanest way to install a never driver version than that available specifically for your distribution is likely to get the source package and rebuild that using the updated nvidia driver package.

I don’t wanted to sound rude, but ubuntu 13.10 has reached end of life in July 17, 2014. So you would better update your system anyway. That way you get newer drivers and other more critical updates for your system.

You will need to kill the Xserver with

killall X or sudo killall X
