Re: occult nvidia kernel version skew -- getting desperate

I haven't been following this thread, but this approach to a problem
seems to me to be overly complicated.

IMHO, you will never be sure that *all* files pertaining to a particular
package have been removed from a malfunctioning computer, whatever the
issue or malfunction. 

You should consider, for *this* situation, starting an install on a
new partition or new hard disk. Preferably, a new clean hard disk. This
way there cannot be any 'nvidia' or whatever. After you have solved
the problem that you attribute to nvidia, you can try installing old
files from backups, if you really need them. Install them a few at
a time, always checking that you have not broken you new, nvidia free,

All this might not be necessary if you felt you were really in charge
of what is on your computer, but IMHO you display a serious lack of
confidence on this point. So do something that puts you in control

And if your new nvidia free installation displays the same wrong
behavior as you now experience, perhaps, just perhaps, nvidia is
not the problem.
