Here's the problem. I got my friend started using Linux a couple of years ago. He lives 350 miles away but I went to see him
a little over a year ago and installed PCLOS for him and he loves it. He calls me to walk him through whatever minor problems
that arise which are almost always self inflicted. I walked him through changing all of the repos and got him set up with the new
ones. Well evidently he went a long time without updating anything and yesterday he opened synaptic and clicked "mark all upgrades"
and there were a lot. After they installed, he rebooted and he's stuck in cli. Apparently he borked his nvidia driver. Now here's my
question...
How can he either re-install the nvidia driver or change to the nouveau driver from cli? I tried the apt-get install nvidia-current
command but that didn't work, he probably doesn't have the right repo enabled.
I'd sure like to get him back to his desktop if possible. I'd have him come here and ask himself but it wouldn't do any good.
I have to spoon feed him everything over the phone.

P.S. Don't hate me.

Added: He doesn't do anything graphics intensive so I'm sure the nouveau driver would be fine if that's easier.
