Bug description:
  Since Maverick, when using the touchpad, it's often not working and stucks for seconds, in short, it is unusesable. This bug still happens in Ubuntu 11.10 on a Lenovo L520 with 3.0.0-13-generic. Its a Synaptics touchpad, maybe it's kernel bug. Dmesg produces the following output:
