tdeering, would you need a backport to a release prior to Raring, or may this be marked Status Invalid? Declining the linux (Ubuntu) task as this is not reproducible in Raring for the original reporter as per https://bugs.launchpad.net/ubuntu/+source/linux/+bug/964231/comments/22 . ** Tags added: needs-bisect needs-full-computer-model needs-upstream- testing ** Description changed: With a fresh install of Ubuntu 11.10 x64, the system has many "microfreezes" when I connect an external monitor via HDMI. These last maybe 10ms and occur about once per second. As I move my cursor around the screen, it stops motion during these microfreezes, causing a very irritating stutter effect. This only happens when using HDMI- when connected via VGA to an external monitor, the system behaves smoothly as - expected. + expected.
