I tried to run the sricpt as you asked but I have some issues... After killing lightdm, I ran the script.
First, "modprobe -r nvidia" said: "module nvidia not found", so I installed nvidia-current.
But then, "modprobe nvidia" said: "Error could not insert "nvidia_304": Unknown symbol in module or unknown paramter".

Did I miss something to do?
