What does it mean when it says 'set to manually installed' when I type in
'apt-get install openssh-server'?

why did the sound stop working?
>>Another problem that just started is the sound on the print server
stopped working. I clicked on the speaker icon >>to turn it up and I see it
is maxed. So then I clicked 'sound settings' and the output volume is maxed
so I >>investigate the tabs. The first tab (hardware) has nothing in the
'choose a device to configure' window. So >>somehow the driver was removed
(I guess).
