Frank, thank you for reporting this and helping make Ubuntu better.
In order to allow additional upstream developers to examine the issue, at your
earliest convenience, could you please test the latest upstream kernel
available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please
keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the
daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was
released upstream.
4) Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds .
If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.
If the latest kernel did not allow you to test to the issue (ex. you couldn't
boot into the OS) please make a comment in your report about this, and continue
to test the next most recent kernel version until you can test to the issue.
Once you've tested the upstream kernel, please comment on which kernel version
specifically you tested. If this issue is fixed in the mainline kernel, please
add the following tags by clicking on the yellow circle with a black pencil
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ
Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.
If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ
Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.
Also, you don't need to apport-collect further unless specifically
requested to do so.
It is most helpful that after testing of the latest upstream kernel is
complete, you mark this report Status Confirmed.
Lastly, to keep this issue relevant to upstream, please continue to test
the latest mainline kernel as it becomes available.
Thank you for your help.

Title:
Intel HD Graphics 520 lagging after kernel upgrade
Status in linux package in Ubuntu:
Incomplete
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.
