After yesterday’s upgrades including libindicator7, unity-greeter crashes repeatedly until failsafe kicks in, and even then, after selecting low graphics mode for the session, it crashes. I managed to get X working again by downgrading unity-greeter back to 0.2.0-0ubuntu4 which I’m filing this report with. The crashing update was version 0.2.0-0ubuntu5.
I’m attaching the crash file.
It seems I’m not able to reproduce this on my other computer (also running up-to-date Precise), so I’ll look for differences in the setups.
