So, sam, this is the bug I can reproduce reliably without the workaround on both my netbooks and sometimes on my laptop, depending on boot.

FYI, I reintroduced the wokaround for the week-end. Hope that + aquarius full backtrace (http://paste.ubuntu.com/559475/ for the record) will help you in your debugging :)

People are getting it with the workaround as well (not on my machine) but at least rickspencer3 and seb128.

To avoid this bug, restart in "recovery mode" and select the option of low resolution. You'll be able to switch to Ubuntu Classic Desktop.
