It seems the problem had existed before in Ubuntu 14.04 and Dell recommended using proprietary drivers for trackpad. Here is the Dell KB with the info: http://www.dell.com/support/article/us/en/19/SLN297219/EN
Just to experiment I tried doing the same with my Ubuntu 16.04 and installed the drivers as instructed in the link. I haven't faced any issues yet (its been two days). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576844 Title: Touchpad/Trackpad freezes then eventually unfreezes (repeatedly) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1576844/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
