Thanks for your report. This could be an intermittent upgrade issue. Is this i386 or amd64?

[Nicola Lunghi (nicola.lunghi)]

i386.... but I have tried to install the fglrx driver.... I Investigate more and then report...

[Bowmore (bowmore)]

The ATI proprietary driver (fglrx) doesn't work until fixed by AMD/ATI.

The workaround is to manually purge fglrx
$ apt-get remove --purge fglrx*

I mark it as a dupe of Bug #313027.
