  Bluetooth mouse laggy and erratic

Bug description:
  I installed Ubuntu 15.04 (64 bit) on a DELL XPS 13 (model 9343, bios
  A03) notebook. I use a DELL bluetooth mouse but sometimes it behaves
  erratically (laggy, jumpy). The problem happens after a few (sometimes
  one) suspend and resume. I am attaching below some info on my system.
  Thank you.
