I am having problems with laggy mouse pointer movement in Ubuntu 16.10. The problem only occures after graphic intensive activities such as playing 1080p videos, browsing high-res images or playing games. When it appears, it persists until I reboot my computer, even logging off and on doesn't help. Also, the problem only appears when I am using integrated touchpad of my notebook - when I connect a USB mouse the pointer moves as usual (but it still lags when I try to use touchpad). I am using NVIDIA GeForce 940MX card with NVIDIA binary driver 367.57.

I found a solution to my problem. At first I rebooted my computer and entered the BIOS settings using F2 key. Then I changed the Touchpad settings from Advanced to Basic.
Please note that this solution is likely to be hardware-specific - I am using Acer Aspire E 15. You can also check out this thread on Ubuntu Forums where I've found it.
