lightdm crashes on startup on 3.2.0-24+ running on MacBookPro 8.2

[Robert]

Trying to boot into Ubuntu, lightdm crashes and I can't get to the UI login screen. I'm running Ubuntu 12.04 kernel version 3.2.0-24 (or 3.2.0-25) on a MacBookPro 8.2. The last version that worked is 3.2.0-23.

dmesg shows the following (hopefully relevant) info:

X/driver crash

[penalvch (penalvch)]

Robert, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg <replace-with-bug-number>

Thank you for your understanding.
