fglrx issue

[Colin Law]

Following on from an earlier thread about an fglrx issue, which was
flagrantly hijacked to talk about compiz et al :)

I have 12.04 running on a machine with a graphics card identified by lspci as
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
RS780D [Radeon HD 3300]
An upgrade to fglrx caused a drop back to unity 2D due to a bug [1].
I installed trusty daily in another partition in order to see whether
the problem also exists there, but on trusty I find that fglrx is not
installed at all yet everything appears to work correctly.  Nothing is
shown in Additional Drivers.

Can anyone suggest what may be going on?
