Hi, i have the same problem on my 12.04 (unity 5.10.0-0ubuntu6) Laptop. I have a Intel® Core™ i7-2720QM CPU @ 2.20GHz × 8 with 12 GB DDR3 RAM and an ATI GPU. I am using the open source driver and not the properitary one.
the Problem: If i enable my 3 screens, everything starts lagging on the screen. If i only use my Laptop i have no problem with that. Please let me know if you need more informations.
