I'm affected by this problem too, on Lenovo Thinkpad L520 running Ubuntu 11.10 amd64. I've built a new vanilla kernel (3.2.0) for 11.10, as well as tried Ubuntu 12.04 alpha 1. However, both are affected by this bug: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/912992

However, I boot Ubuntu 12.04 alpha and test (with an external monitor) if the included 3.2.0 kernel fixes this issue. For me the loss of synchronization occurs failrly often (=several times an hour). I'll report back my findings, hopefully next weekend.
