You have been subscribed to a public bug: I upgraded my system to 12.04 today. After reboot and login, my desktop initially displayed then a slow black screen wash happened from top to bottom. I waited several seconds and eventually the desktop came back with no panel or launcher. I received a crash popup and tried to send it, but the crash reporting process never completed.
I was able to restart X and login using the 2d desktop. The following is an excerpt from a crash file in /var/crash I can send the entire crash file if needed it is over 7mb.: SegvAnalysis: Segfault happened at: 0x7fd4a957b7e5 <_wordcopy_fwd_aligned+181>: mov (%rsi),%rax PC (0x7fd4a957b7e5) ok source "(%rsi)" (0x7fd486ce3800) not located in a known VMA region (needed readable region)! destination "%rax" ok SegvReason: reading unknown VMA SourcePackage: unity Stacktrace: #0 _wordcopy_fwd_aligned (dstp=59130960, srcp=140550771456000, len=640) at wordcopy.c:80 a0 = <optimized out> a1 = <optimized out> #1 0x00007fd4a9575635 in __memmove_sse2 (dest=0x3864450, src=<optimized out>, len=5120) at ../string/memmove.c:76 dstp = <optimized out> srcp = <optimized out> #2 0x00007fd49c7f9753 in ??
