Cannot install latest nVidia driver in kubuntu 12.04

Can you give the output of:

sudo lshw -C display; lsb_release -a; uname -a; dpkg -l | grep nvidia

Thanks

Here is the log:

Try:

sudo apt-get --reinstall install dkms

Then reboot to test

No luck. Still not activated!

The nvidia setting displays the same error message as I stated in the question!

Hi, upgrading the kernal via the moun update manager did the work! Now the nVidia driver is working!
