Offhand this sounds like a "compiz crashed" bug, particularly if you're
finding the issue does not appear with lubuntu or other non-unity
ubuntu's. If this is true, then you should be able to launch a terminal
window via "<ctrl><alt> t" when the system is showing just the
background.
In any case, since this bug was filed originally against linux, it does
not have the X debugging info. Please reproduce the problem and then
run 'apport-collect 1076776'. You may need to ssh into the box while
the system is blank/lockedup/corrupted, so we can see the exact error
state.
If it is compiz crashing, your ~/.xsession-errors may have some more
relevant error message about why compiz crashed.

Title:
12.10: Default background after logon
Status in “linux” package in Ubuntu:
Confirmed
Status in “xserver-xorg-video-nouveau” package in Ubuntu:
Incomplete
Bug description:
After logging onto Ubuntu 12.10, only the default background is shown
and nothing else. This occurs on an HP TC1100 tablet using GeForce4
420 Go 32M
Using Ubuntu 12.04 worked fine before and after logon.
In 12.10, I tested kernel 3.2.0-23 but the same problem occurs.
WORKAROUND: Use the following kernel parameter, but the OS responds slower:
