Kubuntu 12.04 : starting load fallback graphics devices [fail]

Question

Just after booting, while Kubuntu loads its modules and checks all of it, this message appears and the loading work stops.

As a matter of fact the Kubuntu's login screen never comes and it switches automatically on the tty1 in console mode. So I only can use the ttys 1 to 6 in console mode and the tty7 still out of order.

The following procedure to re-install the NVIDIA driver did not work :

1. Remove the existing nvidia driver :

   sudo apt-get purge nvidia-current

2. Upgrade to the new driver: (follow this link)

   sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

   sudo apt-get update

   sudo apt-get dist-upgrade

   sudo apt-get install nvidia-current

Any idea ? Thank you very much for your time.

Answer 1

Fixed !

As the re-installation of the nvidia current driver version did not work I thought to install one other version. This link shows how to install NVIDIA driver on ubuntu : BinaryDriverHowto/Nvidia

So I did exactly the same procedure as above but I replaced

nvidia-current with nvidia-319.

You can access to the possible versions list with auto-completion on :

sudo apt-get install nvidia-

It fully resolved my problem after reboot.

Afterward, I saw that the current version seems to be set on the 304 version but I don't know why precisely.
