    Unity desktop - icons missing, colours changed - ubuntu 12.04

    Hi Folks,

    I believe I'm running ubuntu 12.04, with the Unity window manager/desktop.

    My system has been working fine for months.

    This afternoon, I clicked on the System Settings icon in the bar on the left of the screen. (It's not labelled, so I can never remember what Unity calls that bar.) I think I then selected "appearance". I did not change anything. Almost immediately after that a number of icons disappeared from the bar - I can still hover and get their names, or click on them, but there's no icon. Several screens have changed from purple to blue. That wouldn't bug me - it's nicer than unity's ubiquitous purple - but title bars are unreadable.

    I rebooted - no obvious change resulted.

    I installed a large number of recent updates, using "sudo apt-get update" and "sudo apt-get upgrade", not the annoying GUI tool that sometimes appears on that left-side icon bar. No obvious change.

    I rebooted again. Still no change.

    Missing icons include: "Home Folder", "Terminal", "system Settings", "Angband (X11)", "Workspace switcher", and "trash" - plus any others where there's no hover-over text.

    Would anyone care to hazard a guess as to:
    (1) what might have happened
    (2) how one might fix it
    (3) where to find useful documentation on unity, including where it keeps its icons, config files, etc., and which packages it uses?
    (4) whether this might have been caused by some kind of automatic update, and if so, how to identify and disable it? I really don't appreciate systems that suddenly stop working without me changing anything! If I wanted that, I could install windows.

    Thanks for any insight.

    [Update - I've got a lot of complaints in $HOME/.xsession-errors, with things like:

    ** (gnome-control-center:2880): WARNING **: Could not find icon

    This would be so much useful if the error message had included (a) what icon it was looking for (b) where it was looking.

    At least it gives me a software component - with man page - to look at.
