Title:
  Intermittent screen blinking with 4k external mini display port with
  4.4 kernels

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Xenial:
  Confirmed

Bug description:
  When using an external 4K monitor plugged into the mini display port on my 
Dell XPS 13 9343 using both the laptop screen and the external monitor 
(external monitor is left and laptop screen right), when using all of the 
following kernels:
  4.4.0-2.16-generic
  4.4.0-4.19-generic
  4.4.0-6.21-generic
  4.4.0-7.22-generic

  the external monitor will sometimes blink off for about a second or
  two, then back on. What is weird is this seems to only happen when
  typing into a gnome-terminal as opposed to firefox or evolution.
  Simply changing to a gnome-terminal and typing into it doesn't cause
  the blinking, but it might happen immediately or it might take several
  minutes.

  4.3.0-7.18-generic worked fine and I can go hours and hours in a
  gnome-terminal with no issues.

2016-05-26 Thread Joseph Salisbury
I built the next test kernel, up to the following commit:
a2736b07df1f17c24c8890eb7b2dac529d9725d3

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1547619

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

I have booted into this kernel:

Since the bug doesn't always show itself right away, I will want to use
the kernel for at least several hours. I'll report back as soon as I see
the bug or after using the computer throughout the day.

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-05-24 Thread Jamie Strandboge
I have booted into this kernel:

$ cat /proc/version 
Linux version 4.3.0-040300rc5-generic (jsalisbury@gomeisa) (gcc version 5.2.1 
20151010 (Ubuntu 5.2.1-22ubuntu2) ) #201605201447 SMP Fri May 20 18:50:00 UTC 
2016

Since the bug doesn't always show itself right away, I will want to use
the kernel for at least several hours. I'll report back as soon as I see
the bug or after using the computer throughout the day.

  When using an external 4K monitor plugged into the mini display port on my

(external monitor is left and laptop screen right), when using all of the

  the external monitor will sometimes blink off for about a second or
  two, then back on. What is weird is this seems to only happen when
  typing into a gnome-terminal as opposed to firefox or evolution.
  Simply changing to a gnome-terminal and typing into it doesn't cause
  the blinking, but it might happen immediately or it might take several
  minutes.

Title:
  Intermittent screen blinking with 4k external mini display port with
  4.4 kernels

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Xenial:
  In Progress

Bug description:
  When using an external 4K monitor plugged into the mini display port on my 
Dell XPS 13 9343 using both the laptop screen and the external monitor 
(external monitor is left and laptop screen right), when using all of the 
following kernels:
  4.4.0-2.16-generic
  4.4.0-4.19-generic
  4.4.0-6.21-generic
  4.4.0-7.22-generic

  the external monitor will sometimes blink off for about a second or
  two, then back on. What is weird is this seems to only happen when
  typing into a gnome-terminal as opposed to firefox or evolution.
  Simply changing to a gnome-terminal and typing into it doesn't cause
  the blinking, but it might happen immediately or it might take several
  minutes.

  4.3.0-7.18-generic worked fine and I can go hours and hours in a
  gnome-terminal with no issues.

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-05-16 Thread Jamie Strandboge
I have booted into this kernel:

$ cat /proc/version
Linux version 4.3.0-040300rc5-generic (jsalisbury@gomeisa) (gcc version 5.2.1 
20151010 (Ubuntu 5.2.1-22ubuntu2) ) #201605111621 SMP Wed May 11 20:26:24 UTC 
2016

Since the bug doesn't always show itself right away, I will want to use
the kernel for at least several hours. I'll report back as soon as I see
the bug or after using the computer throughout the day.

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-05-11 Thread Joseph Salisbury
I built the next test kernel, up to the following commit:
c0f3f90cf454dd845dcc443afa4f0e312a8eaee0

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1547619

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

Ah, that was fast. This kernel has the bug:

$ cat /proc/version
Linux version 4.3.0-040300-generic (jsalisbury@gomeisa) (gcc version 5.3.1

  When using an external 4K monitor plugged into the mini display port on my

  the external monitor will sometimes blink off for about a second or
  two, then back on. What is weird is this seems to only happen when
  typing into a gnome-terminal as opposed to firefox or evolution.
  Simply changing to a gnome-terminal and typing into it doesn't cause
  the blinking, but it might happen immediately or it might take several
  minutes.

  4.3.0-7.18-generic worked fine and I can go hours and hours in a

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-05-09 Thread Jamie Strandboge
Apologies for the delay-- I needed our Ubuntu kernel for a number of
weeks and had to pause this bisection.

I have booted into this kernel:

$ cat /proc/version 
Linux version 4.3.0-040300-generic (jsalisbury@gomeisa) (gcc version 5.3.1 
20160311 (Ubuntu 5.3.1-11ubuntu1) ) #201603151533 SMP Tue Mar 15 19:37:15 UTC 
2016

Since the bug doesn't always show itself right away, I will want to use
the kernel for at least several hours. I'll report back as soon as I see
the bug or after using the computer throughout the day.

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-05-02 Thread Onno Steenbergen
Having this issue as well. Blinking happens on mini displayport not on
mini HDMI (running on Intel NUC with dual monitor setup). Some
applications trigger the blinking more often than others. Blinking
occurs every few minutes when working in a terminal, but it can happen
multiple times in a row. Switching to (or away from) the terminal
triggers the bug more often than just working in the terminal.

$ cat /proc/version_signature 
Ubuntu 4.4.0-21.37-generic 4.4.6

I built the next test kernel, up to the following commit:
b44a3d2a85c64208a57362a1728efb58a6556cd6

The test kernel can be downloaded from:

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-03-10 Thread Joseph Salisbury
I built the next test kernel, up to the following commit:
e6604ecb70d4b1dbc0372c6518b51c25c4b135a1

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1547619

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

People reported 4.5.0-040500rc6 fixes the bug for them.

You can see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1488719
for reference

I am on 4.5.0 RC6 myself and for me it is not fixed. It is a lot better,
screen blinking is reduced a lot but it still happens from time to time.

2016-03-04 Thread Gronor
Hi, just to add some info to this really annoying bug.
I am using external monitors connected through a display port hub which in turn 
connects to my laptop mini display port.
What I noticed is that this only happens when my monitors are at the 1920 x 
1080 resolution. If I switch to 1280 x 1024, this never ever happens.

  Simply changing to a gnome-terminal and typing into it doesn't cause
  the blinking, but it might happen immediately or it might take several

I saw a new kernel in xenial with intel fixes so I decided to try it.

This kernel has the bug:
$ cat /proc/version_signature 
Ubuntu 4.4.0-9.24-generic 4.4.3

I'll try the bisected kernel now.

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-03-01 Thread Joseph Salisbury
I started a kernel bisect between v4.3 final and v4.4-rc1. The kernel
bisect will require testing of about 13 test kernels.

I built the first test kernel, up to the following commit:
118c216e16c5ccb028cd03a0dcd56d17a07ff8d7

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1547619

Can you test that kernel and report back if it has the bug or not?  I
will build the next test kernel based on your test results.

Thanks in advance

  When using an external 4K monitor plugged into the mini display port on my 
Dell XPS 13 9343 using both the laptop screen and the external monitor 
(external monitor is left and laptop screen right), when using all of the 
following kernels:
  4.4.0-2.16-generic
  4.4.0-4.19-generic
  4.4.0-6.21-generic
  4.4.0-7.22-generic

  the external monitor will sometimes blink off for about a second or
  two, then back on. What is weird is this seems to only happen when
  typing into a gnome-terminal as opposed to firefox or evolution.
  Simply changing to a gnome-terminal and typing into it doesn't cause
  the blinking, but it might happen immediately or it might take several
  minutes.

  4.3.0-7.18-generic worked fine and I can go hours and hours in a
  gnome-terminal with no issues.

2016-02-23 Thread Joseph Salisbury
Thanks, Jamie.  If we can identify which 4.4 release candidate the
regression was introduce, we might be able to switch back to Ubuntu
kernels for the actual bisect.

Can you test the following upstream kernel to see if it has the bug:

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-02-23 Thread Jamie Strandboge
It is difficult for me to use a non-Ubuntu kernel since I do a lot of
work with apparmor for the distro. I suppose I could try for a little
while at a time, but my ability to test will be impeded (ie, I'll need
to run mainline only when not doing the other work).

I've been trying to get early Ubuntu 4.4 kernel to build, but not having
much luck.  Are you unable to test mainline kernels on this system?  It
would make the bisect much faster.

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-02-22 Thread Joseph Salisbury
I built a 4.4.0-0.3 kernel which was based off of upstream 4.4-rc4.
This kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1547619/

Can you see if this kernel has the bug or not?

  Intermittent screen blinking with 4k external mini display port with

Bug description:
  When using an external 4K monitor plugged into the mini display port on my 
Dell XPS 13 9343 using both the laptop screen and the external monitor 
(external monitor is left and laptop screen right), when using all of the 
following kernels:
  4.4.0-2.16-generic
  4.4.0-4.19-generic
  4.4.0-6.21-generic
  4.4.0-7.22-generic

  the external monitor will sometimes blink off for about a second or
  two, then back on. What is weird is this seems to only happen when
  typing into a gnome-terminal as opposed to firefox or evolution.
  Simply changing to a gnome-terminal and typing into it doesn't cause
  the blinking, but it might happen immediately or it might take several
  minutes.

  4.3.0-7.18-generic worked fine and I can go hours and hours in a
  gnome-terminal with no issues.

2016-02-22 Thread Joseph Salisbury
Thanks for testing, Jamie.  This would indicate the bug was introduced
somewhere in late 4.3.  I'll figure out the best next kernel to test and
post it shortly.

I'd like to perform a bisect to identify the commit that introduced this
regression.  To narrow the bisect window, can you test the 4.4.0-1.15
kernel first?  It can be downloaded from:

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-02-22 Thread Jamie Strandboge
** Description changed:

Dell XPS 13 9343 using both the laptop screen and the external monitor 
(external monitor is left and laptop screen right), when using all of the 
following kernels:
+ When using an external 4K monitor plugged into the mini display port on my 
Dell XPS 13 9343 using both the laptop screen and the external monitor 
(external monitor is left and laptop screen right), when using all of the 
following kernels:
  4.4.0-2.16-generic
  4.4.0-4.19-generic
  4.4.0-6.21-generic
  4.4.0-7.22-generic
  
  the external monitor will sometimes blink off for about a second or two,
  then back on. What is weird is this seems to only happen when typing
  into a gnome-terminal as opposed to firefox or evolution. Simply
  changing to a gnome-terminal and typing into it doesn't cause the
  blinking, but it might happen immediately or it might take several
  minutes.
  
  4.3.0-7.18-generic worked fine and I can go hours and hours in a gnome-
  terminal with no issues.

2016-02-22 Thread Jamie Strandboge
I have booted into this kernel:

$ cat /proc/version_signature 
Ubuntu 4.4.0-0.10Commit3b7e590bf-generic 4.4.0

Since the bug doesn't always show itself right away, I will want to use
the kernel for at least several hours. I'll report back as soon as I see
the bug or after using the computer throughout the day on Monday.

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

2016-02-22 Thread Joseph Salisbury
I was unable to bisect between 4.3.0-7.18 and 4.4.0-1.15-generic because
the commits are not linear.  Due to this, we should test and confirm
4.4.0-0.10 does not have the bug.  It shouldn't.

Once we confirm that, I can start a bisect between 4.4.0-0.10 and
4.4.0-1.15-generic.

I built a 4.4.0-0.10 kernel which can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1547619/
