Bug Description
After upgrading to kernel version 4.4.0-53 on a clean install of Lubuntu, I have experienced a persistent problem where the desktop graphics (or any graphics when not using tty 1 to 6) appear to lag or freeze every 1 to 2 seconds for between 0.5 to 1 second. During the freezes, no mouse input is recorded, and most keyboard input is lost.
I'm fairly sure this is a kernel issue, as booting with kernel 4.4.0-31 fixes the issue. This problem is also present in 4.4.0-57.
I am using a Lenovo ThinkPad X1 Carbon with integrated Intel graphics, which aren't the most powerful (they couldn't handle Unity, hence Lubunut). I am running Lubuntu 16.04 LTS, though I have tried a clean install (from the .iso) of Lubuntu 16.10, and this but still appears. The laptop has a4 core i5-6200U processor (2.3 GHz), 8 Gigs of RAM, and Intel HD Graphics 520 (Skylake)
This does not appear to be a thermal issue, or a processor speed issue (the problem persists weather speed step is enabled in the bios or not), though my testing with processor speed step and kernel performance settings (performance/power save) was at best amateur.
