I don't think it's a problem with compiz nor nvidia-comon. The same happened to me this morning with upgrade. In the morning I was still on 10.10.
from apt/history.log (I removed some packages like thunderbird from the list) : Upgrade: linux-image-2.6.35-30-generic:amd64 (2.6.35-30.60, 2.6.35-30.61), linux-generic:amd64 (2.6.35.30.38, 2.6.35.30.39), linux-headers-2.6.35-30-generic:amd64 (2.6.35-30.60, 2.6.35-30.61), tzdata-java:amd64 (2011j-0ubuntu0.10.10, 2011k-0ubuntu0.10.10), linux-headers-generic:amd64 (2.6.35.30.38, 2.6.35.30.39), linux-image-generic:amd64 (2.6.35.30.38, 2.6.35.30.39), linux-headers-2.6.35-30:amd64 (2.6.35-30.60, 2.6.35-30.61), ibpq-dev:amd64 (8.4.8-0ubuntu0.10.10, 8.4.9-0ubuntu0.10.10), tzdata:amd64 (2011j-0ubuntu0.10.10, 2011k-0ubuntu0.10.10), libpq5:amd64 (8.4.8-0ubuntu0.10.10, 8.4.9-0ubuntu0.10.10), linux-libc-dev:amd64 (2.6.35-1030.60, 2.6.35-1030.61), After that I tried nouveau, starting with older kernel, upgrade to natty, xorg-edgers ...
