Jacob Zimmermann, in order to allow additional upstream mainline kernel
developers to examine the issue, at your earliest convenience, could you please
test the latest mainline 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 mainline kernel, please comment on which kernel version
specifically you tested. If this issue is not reproducible 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 issue is reproducible with the mainline kernel, 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 mainline 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:
Major performance regression from Ubuntu 17.10 with i915
Status in linux package in Ubuntu:
Incomplete
Bug description:
Desktop performance on my laptop (Intel HD 520, driver: i915) used to
be generally good on previous Ubuntu releases but on 18.04, there is a
VERY noticeable regression. Moving windows around in GNOME is choppy
and tearing. It gets dramatic after the laptop resumes from suspend,
GNOME drops to literally ~1-2 FPS. Logging out and restarting the
session usually fixes the problem in that it restores the barely
acceptable performance level prior to suspend.
