I have purchased Dell inspiron few days back with Nvidia GT640M graphics card.
Now I want to install supporting drivers for ubuntu 12.04 64 OS but unable to do so.
I tried all effort using ubuntu forums. But nothing solves the problem.
Once I install nvidia-current drivers from linux developers or from nvidia website, my resolution goes to ~600x600 something like.
I am forced to delete then xorg.conf.
Please help if anyone have encountered this problem or any resolution.
