Have you guys tried uninstalling the Intel Xorg driver so you default
to kernel mode settings. That solved a lot of flicker issues for me.

$ sudo dpkg --purge  install xserver-xorg-video-intel

[Brad Buran]

Same here. It appears to have reappeared using the XPS9350.
4.10.0-21-generic. Flickering is intermittent (e.g., once a day) and
goes away if I resize the window I'm currently using.

Same here. I upgraded from Xubuntu 16.04 to 17.04 maybe a month ago and
that finally fixed my screen flickering issue, but it has now returned.
I have been seeing it again at least couple of days now.

Running kernel 4.10.0-21-generic on Asus Zenbook laptop with Intel
Skylake.

I can happily confirm that this does not occur anymore on Ubuntu 16.04 (
kernel 4.4) .

[John Smith]

I'm having this same issue on a Dell 7537 running Ubuntu 16.10 (kernel
4.8).

The flickering that occurs is a rapid change in the brightness of the screen, 
in a random, persistently manner (it never stops).
Not so often the screen goes all white and quickly returns to normal.

It's interesting to mention that on Ubuntu 16.04 (kernel 4.4) the bug
appears to be fixed, as the flickering does not occur.

Guys, there is an entry on the Chromium site talking about xorg modesetting
vs intel xorg driver. By installing modesetting module and getting rid of
the intel driver, the flicker was gone completely on Ubuntu 16.04.

[Bug 1554613] Re: Screen flickers on XPS 13 9350/9550 (Intel Skylake/Broadwell GPU)

[Sukttarb]

On my Dell XPS 13-9350, I had been running 4.4.0-38.57 for two weeks and
continued to experience screen flash while using google-chrome-beta
until updating this morning to 54.0.2840.50-1. No more flash. Halleluja!

At least for my DELL 3800, current kernel in Ubuntu Xenial, 4.4.0-38.57,
fixes the flickering

Yikes. In your case it isn't the browser for sure. I read somewhere that
the adaptive brightness control might be a culprit but don't count on that
being true unless confirmed.

[Thiago Martins]

Anmar,

I am 100% sure that it is not the browser, please guys, watch this:

https://www.youtube.com/watch?v=BC287yYPfTA

This BUG is not fixed. Or maybe, what I'm seeing here is a different
bug.

On Ubuntu 16.10, things looks a little bit better but, Chrome still
flickers.

Ubuntu 14.04 is fine. While 16.04 and 16.10 are just terrible.

Chrome flickers... but FF doesn't for me. Are you sure it isn't the
browser.

I'm on 4.4.0-28-generic (Xenial), problem still here.

A good website to test it, is TradingView:

https://www.tradingview.com/chart/7ipqeH3N/

Google Chrome window flickers a lot! Especially if you really use the
above website, by login in, clicking on its functions, pop-up windows
and etc...

Hardware is a Macbook Pro, end-2015.

[Bug 1554613] Re: Screen flickers on XPS 13 9350/9550 (Intel Skylake/Broadwell GPU)

[Alexander Vinbæk Strand]

Still no problems with Linux Mint 18 beta, and I found out that Linux
Mint 18 use the same kernel and driver as Ubuntu 16.04, so why does
everything work in Linux Mint 18 Beta when not in Ubuntu 16.04?

I have the same card and I have the same problem with Ubuntu earlier as
this bug is for, but after I installed Linux Mint instead of Ubuntu then
I can't see any problems with graphics.

I don't know if I can help, but here is some files from my computer with
logs and information that I hope can be used to fix the bug in Ubuntu.

Here is the output of:

lsb_release -a
Distributor ID: LinuxMint
Description:Linux Mint 18 Sarah
Release:18

I can help with testing Linux Mint 18 beta on different kernels if you
want, so I can see if I get the same problem as Ubuntu with the Intel
graphics card, but only if someone can tell me what i should test, and
how to do it, because I have never done that before, but I want to find
out if there is just the kernel Linux Mint 18 uses that is not affected
or there is a fix on Linux Mint that Ubuntu does not have, because if
there is a fix, then I think we also can use it on Ubuntu.

I have this bug with Ubuntu only.
Linux mint 18 beta cinnamon (based on Ubuntu 16.04) does not have that that 
problem. 
Maybe the Mint team have found a fix that could also be used on Ubuntu.

I don't know if Ubuntu uses different kernel than Mint.

I want to share my experience: I have a Dell XPS 13 9350 QHD SSD: 512GB RAM: 
16GB. Bios 1.3.3.
I installed plain Ubuntu 16.04 erasing all Windows partitions. I did not apply 
any workaround (I read about this bug).
I do NOT experience this bug.

In the meantime I stambled upon these link, according to which TLP causes 
screen flickers:
https://ubuntu-mate.community/t/solved-screen-flickering-only-when-on-battery-skylake-16-04/5201/21

I don't know if it is the same problem, but you may try to
disable/remove TLP.

@Vasya: seems a different problem. The flickering which this bug is
referring to is application-independent, and visible in the full
screen(s).

I have flickering problem in Chrome on my ASUS UX301LA laptop. The funny
thing is that latest kernel (4.6) doesn't fix anything.

@romano-giannetti and anyone who followed the instructions referenced in 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1554613/comments/125,
There was a typo in instructions, please read bug description for details and 
fix.


** Description changed:

  *** Temporary workaround ***
  Install Kernel from the following location:
  - http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-yakkety/
  
  OR
  Perform the following:
  - $ apt-add-repository "deb 
http://ppa.launchpad.net/canonical-kernel-team/ppa/ubuntu yakkety main"
  - $ echo -en "Package: *\nPin: release 
o=LP-PPA-canonical-kernel-team-ppa\nPin-Priority: -1\n" >> 
/etc/apt/preferences.d/canonical-kernel-team-ubuntu-ppa-yakkety
  - $ apt update
  - $ apt install linux-image-extra-4.6.0-6-generic 
linux-headers-4.6.0-6-generic linux-tools-4.6.0-6-generic
+ ```
+ There was a typo in instructions (/etc/preferences.d should have been 
/etc/apt/preferences.d).
+ As result you might have upgraded Linux META packages and therefor you won't 
receive proper upgrades of Xenial native Linux packages (hoping they will ever 
contain the fix).
+ I suggest you move 
/etc/preferences.d/canonical-kernel-team-ubuntu-ppa-yakkety to 
/etc/apt/preferences.d/ and downgrade related packages:
+ $ apt update
+ $ apt install linux-headers-generic/xenial-updates 
linux-tools-generic/xenial-updates linux-image-generic/xenial-updates
+ ```

I had this problem with a Dell desktop; It was especially bad with the
second monitor, which blanked out every time it lost focus. I can
confirm that

- $ apt-add-repository "deb 
http://ppa.launchpad.net/canonical-kernel-team/ppa/ubuntu yakkety main"
- $ echo -en "Package: *\nPin: release 
o=LP-PPA-canonical-kernel-team-ppa\nPin-Priority: -1\n" >> 
/etc/preferences.d/canonical-kernel-team-ubuntu-ppa-yakkety
- $ apt update
- $ apt install linux-image-extra-4.6.0-6-generic linux-headers-4.6.0-6-generic 
linux-tools-4.6.0-6-generic

after having created the directory /etc/preferences.d manually, and so
upgrading to the yakkety kernel, fixed the issue.

Can anyone please post the instruction to revert this and go back to
normal Xenial kernel release when the bug is fixed there? Thanks!

Amazingly, Bluetooth ON/OFF seems to have an effect on this bug. I have
been running with Bluetooth constantly ON for the past couple of days
and have seen no flicker at all. As soon as I turn off Bluetooth a
flicker occurs after a couple of minutes. I also copied the firmware
file from the Windows drivers for the Dell Wireless 1830 card as
Bluetooth wasn't finding any devices without it. I am not 100% sure, but
I think before adding the bluetooth firmware I got flicker with
Bluetooth ON as well. You can get the firmware file from this thread -
https://bbs.archlinux.org/viewtopic.php?id=204739

I am running an XPS 9550 with an i7-6700HQ.

I've installed the following Mainline PPA kernel on today's Ubuntu MATE
16.10

  * http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc7-yakkety/

All screen flicker is gone. Just running Ubuntu MATE 16.10, without this
kernel upgrade, the flicker was still present.

@Brad, are you using Ubuntu MATE by chance? I've long suspected that the
MATE desktop environment (or at least Ubuntu MATE) has its own
flickering issue that is not related at all.

@eugenesan but the workaround you posted in the summary lists mainline
kernels. These kernels still have the problem so they are not work
arounds. The link posted by @bettini will solve the current problem, but
they have other bugs(suspend resume bug). So there is no current work
around for this problem without introducing other bugs.

@bettini
I guess any 4.6.0rc+intel-drm-next starting 20160420 should work, but I 
personally tested only the ones documented as a workaround in this bug 
description.

@pranith
On my system, 4.6.0rc3+intel-drm-next solved the issue.
Other people report solution only with more recent version, 
4.6.0rc5+intel-drm-next.
The difference in reports might be related to installed BIOS version or/and 
power management behavior in different conditions.
Anyways, I highly recommend updating XPS systems to BIOS v1.33 since it fixes  
so called "blank screen" issues which might be related.

@eugenesan Does the temporary workaround fix this issue? AFAIK, it is
still present in 4.6 rc mainline kernels and only fixed in intel-drm-
next which will go to 4.7-rc1.
