No, only in that terminal session.  All graphical desktop applications
run under the user which logged in to the graphical desktop.

Uh, you saw it where?  I hope you meant /etc/modprobe.d.  That's where
it has to be.

It's just as well.  But to keep airflow within the system as the designers
assumed, it's a good idea to install a slot cover where the card used
to be, if you have one.

That web page is all one continuous narrative.  Assume that it goes
in the last directory "cd"ed to unless otherwise noted.

Strictly speaking, UTF-8 is a type of character encoding and can be used
with multiple file formats, not just plain text.

OK, so where do we go from here?  First, verify that "local" is indeed
present in /etc/modprobe.d.  Second, verify that /etc/modprobe.conf does
*not* exist.  Third, issue

cat /etc/modprobe.d/local

and make sure its outut is as expected (i.e. the file is in plain text format.)
Fourth, issue "lsmod" and check to make sure that the
blacklisted module is not loaded.  If all three of these things check
out, then I'd like to see the output of dmesg.

Also, check to make sure that the following packages are installed:

alsa-base
alsa-utils

(You can check by means of

   dpkg-query -l alsa-base|grep ii

for example.)

Also, try another "lspci" to see if removing the internal modem card
also resulted in the Intel audio controller disappearing.
