  Plugging HDMI screen in causes system hang

Status in linux package in Ubuntu:
  Fix Released

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

Cannot plug in my second monitor, it locks the system up until I unplug
it.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[cement_head]

@aluvian This might be a longshot, but you might try adding the System76
PPA and installing their nVIDIA driver.  The reason?  All of their
laptops are custom spec'd laptops made by CLEVO, so thier custom tweaks
might help you.  The other thing to try and helped my situation (I do
not have the nVIDIA driver) is to download the Intel Linex Driver tool
and run that.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[aLuViAn]

Hi,

I have been experiencing the same behavior as well on Ubuntu 16.04 LTS.
Just bought a new laptop (Got it from China - Hasee ZX8-KP5D1, basically Clevo 
PM7xxDM) The basic specs are :

Core i5 7th Gen. 7400
nVidia GeForce 1070 GTX
LCD FHD
(Let me know if it needs more info)

When I connect HDMI to an external monitor, I can't see anything on the 
external monitor and my LCD built-in display crashes. The mouse pointer does 
not move - or has a huge lag and jumps from one side to the other side - 
nothing can be opened. The only solution is hard reboot.
Even if I connect HDMI before boot, Ubuntu desktop behaves the same way.
Now I am using miniDisplay port with VGA adapter. It works fine unless the 
screen goes off (Due to  inactivity) and turns back on. Then The external 
monitor won't turn on, though I can see it in my "displays" screen. If I 
disconnect and reconnect, everything is back to normal (I guess this one is not 
related to the bug)

@johnnynobody,

Please file a new bug.
Also, I don't think all DC codes are in the mainline yet. The easiest way to 
"solve" the issue is use AMDGPU-Pro from AMD.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[johnnynobody]

I have this problem running 16.04.3 with the kernel package and drivers
from https://github.com/M-Bab/linux-kernel-amdgpu-binaries. Those
binaries are the only solution that I've found to fixing the problem of
the display going to a blank screen and won't "wake up". But when I try
to use the HDMI port the screen goes blank and won't wake up and nothing
gets displayed on the TV - I'm still able to ssh in from another PC and
reboot the PC that's "frozen" but I don't get a login screen if I leave
the HDMI cable plugged in. I have tried the oibaf and padoka
repositories, also, but that hasn't solved the problem either.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Maik Ihde]

Similar behavior on a Dell Latitude 5470 w/ Intel/AMD Dual graphics with
Mint 18.1. Suspend didn't work with the standard kernel (Display dark,
total freeze) but 4.5.2 helped. However Plugging in or out the VGA Cable
makes it freeze.

Yesterday updated to Kernel 4.8.0-42-generic x86_64 but still freezes
when (un-)plugging VGA. A tail on syslog with a kerlen Oops (via ssh
before it died) is attached together with output of "inxi -Fxz"


** Attachment added: "kernel oops and inxi output"

[Luís Fernando Heckler]

I was experimenting similar behaviour using kernel 4.6.0 x86_64 (linux
mint + cinnamon).

After upgrading to  4.8.0-040800-generic x86_64 seems fine now.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Fabrizio Bertoglio]

Hello,

I have Linux Mint 18 with two cards:

Card-1: Intel Haswell-ULT Integrated Graphics Controller
Card-2: Advanced Micro Devices [AMD/ATI] Sun LE [Radeon HD 8550M / R5

As I had this issue upgrading to Kernel: 4.6.0-040600-generic x86_64 (64
bit gcc: 5.3.1) solved it.

Lately I experimented some screen flickering and some tear dropping,
especially when I remove the External Monitors.

What Kernel should I install?

Thanks
Fabrizio Bertoglio

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Laurent]

I had the exact same issue on a Lenovo Thinkpad 13 (Intel core i5 6200
with skylake graphics) with Linux Mint 18 (based on 16.04 xenial)
running ubuntu kernel 4.4.0-21. Upgrading to kernel 4.4.31 from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.31/ fixed it.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Usievaład Čorny]

I had this issue with Ubuntu 16.04 (4.4.something).
After upgrade to 16.10 (4.8.0-17-generic) issue is still reproduced.
NVIDIA Corporation GM204M [GeForce GTX 970M], eDP, DP and HDMI connected. 
Without HDMI works well.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Roi Rosenthal]

switched to kernel 4.7.2, seems to improve/solve the issue.
definitely improvement of the lag when detecting a new display and returning to 
responsive state.

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Mikko Pesari]

Still freezes when using DisplayPort on kernel 4.4.0-24. Tested with
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7-rc3-yakkety/ and DP
works fine - however, display is not recognized when using VGA.

  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1

  If I plug in an external HDMI monitor (FHD) either into either HDMI

  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Mikko Pesari]

Hmm, looks like it's not completely fixed on 4.4.0-23 after all. HP
EliteBook 840 G3 has DisplayPort and VGA connectors. With VGA connector
everything works fine but with DP I get a freeze when disconnecting the
cable and sometimes when changing mode between mirror, extended, 1
display configurations.

[Timo Aaltonen]

Christian: your cpu is broadwell, not skylake like for others on this
bug. Broadwell uses the stock i915 driver from 4.4, so file a new bug.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[cement_head]

@dev1 Does your bug occur when using an upstream kernel?

You can test by (a) installing GRUB Customizer
(https://launchpad.net/~danielrichter2007/+archive/ubuntu/grub-
customizer) and then installing (b) an upstream kernel, say 4.6.x
(http://ubuntuhandbook.org/index.php/2016/05/install-linux-
kernel-4-6-ubuntu-16-04/).

The run GRUB customizer and choose the 4.6 kernel.  Reboot & test.  If
something goes wrong, choose your old kernel and uninstall the 4.6.x
kernel.

I've also seen this bug with Sky Lake and the mini-display to VGA
adapters. But I agree with @tjaalton, I do not think this is your bug.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Christian Sarrasin]

@Timo: ok thanks for letting me know but your terse reply eludes me
somewhat.  Are you suggesting - despite similarities in symptoms and
context - that:

1. My problem is different therefore I need to raise a new one?
2. There is another bug to which I should attach this?
3. My contribution is garbage/noise?
4. Anything else?

TiA

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Christian Sarrasin]

This has been happening to me for about ~2 months too: hangs, typically
after resuming from suspend, either immediately after resume or within a
couple of minutes.  Hard power-cycle by holding down power button is
only way out (CTRL+ALT+F1 unresponsive and entire laptop appears
frozen).

Think it's definitely related to external displays (I use a mini-DP
cable) as I don't seem to have the issue when just using the laptop's
internal screen.

Environment: 
* ThinkPad X1 Carbon 3rd Gen (2015, Broadwell)
* Integrated Intel HD5500 graphics
* Stock Ubuntu 14.04/Unity with Kernel 3.19.

The attached crash log has no less than 2549 occurrences of the ominous
"[drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt
lied (SDE)!".  These tend to occur more often just before freezes and
suggest the following might be related:

I don't use MATE either. I am using 16.04 LTS but I have the same
problem as it is described in this bug. Besides the bug report mentioned
above is a duplicate of bug #1574347.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Christoforos Samaras]

@cement_head (andor-udel) yes I went into the folder I had extracted tar
ball, made the install.sh executable (sudo chmod ug+x install.sh) and
afterwards I ran ./install.sh

Now I enabled the xenial-proposed option (settings -> software
-> Developer Options -> run in terminal ''sudo update dist-upgrade'') to
install the latest kernel and everything runs fine. I only have a
problem when I resume from suspension with network manager. It uses
wrong icons (when I am wireless connected I see the ethernet connection
icon (2 arrows)). The problem is fixed if I restart network manager
(sudo service network -manager restart). It's the bug reported here

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

[Timo Aaltonen]

marking fix committed as i915_bpo update to v4.6(-rc7) is now in
proposed

dmc fw version has nothing to do with this, and yes 16.04 has the latest
one already

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[cement_head]

@christoforos-samaras How do you update the Sky Lake firmware once
you've downloaded the tar ball?  Do you just run the install script?

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Christoforos Samaras]

After disabling in my Dell screen MST support (DP 1.2 disabled), did a
firmware upgrade from the following link
https://01.org/linuxgraphics/downloads/skylake-dmc-1.26 and applying the
kernel images located in http://koti.kapsi.fi/~tjaalton/skl/mst ,now
system works fine. I had no freezes and I was able to suspend / resume
the system without issues.

Images used (linux-image-4.4.0-23-generic_4.4.0-23.40~bpo1_amd64.deb and
linux-image-extra-4.4.0-23-generic_4.4.0-23.40~bpo1_amd64.deb)

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[cement_head]

I should mention that I have the Xorg Edgers PPA enabled and use their
graphics drivers (stack).

Although I think that Xenial is pretty up-to-date right now...

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Mondane]

Sadly, kernel 4.4.0-22.40 still gives me problems when moving the mouse
from the external monitor (connected with VGA) to the laptopscreen. I'm
hoping 4.6 will come to Ubuntu as it's being tested for a related
problem here:

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[cement_head]

Okay.  Kernel update 4.4.0-22.40 is working without issues, plugging in
HDMI, plugging in VGA (probably HDMI>VGA on-board) is also working
without issue(s).

Looks as though this finally got fixed - it's a bit ridiculous that this
took so long for an LTS kernel on a widely used chipset (Intel HD / Sky
Lake).

Anyway, thanks!

unplug it afterwards and plug it again the system gets freezing. And if
this  does not happen in the 2nd time it will definitely happen in the
third time. I tested this 4 times and my system went freezing all of
them after plugging/unplugging the cable for 2nd or 3rd time.

  Plugging HDMI screen in causes system hang

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Brian J. Cohen]

After some struggling I was able to boot your 4.4.0-23-generic #40~bpo1
and it appears to function at least as well as 4.6.0 rc7 did with
regards to the freezing.

Nope. After doing that, now I can't run an upgrade:

sudo apt-get upgrade
[sudo] password for X: 
Reading package lists... Done
Building dependency tree   
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 linux-signed-image-4.4.0-22-generic : Depends: linux-image-4.4.0-22-generic (= 
4.4.0-22.39) but 4.4.0-22.39+bpo2 is installed
E: Unmet dependencies. Try using -f.

apt install linux-image-4.4.0-22-generic=4.4.0-22.39 linux-image-
extra-4.4.0-22-generic=4.4.0-22.39

should downgrade those and make apt happy, then you can install
-23.40~bpo1 from the url without worries, and that'll upgrade to proper
-23.40 once it's available, or you can purge them after testing

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Christoforos Samaras]

I installed images (I had to run 'apt-get -f install') and my machine
boots fine. I noticed the following issues though:

I have connected 2 Dell U2415 monitors to my Latitude E7470. I managed
to have them connected with daisy chaining but what I am writing below
happened in bot cases (2 monitors in daisy chain or 1 monitor in HDMI
and 1 in miniDP).

Now my machine does not hang when it resumes from suspension but when it
tries to get suspended. Actually when the system is getting into
suspension mode I have noticed that the screen which is connected to the
HDMI port (when i had them in daisy chain it was the other screen which
is directly connected to the laptop) is flickering and let's say that in
10 times I tried top suspend my system get frozen in half of them. I
also had the following issue: When I was suspending my system with power
cable on and I was removing it before I was trying to resume, my system
when I was pressing the power button to wake it , It was not getting
back but it was restarting (reboot). I also noticed too many hangs
during suspension when I was trying to suspend through command line with
'systemctl suspend' command.

If you think I have to post some logs tell me which ones you would like
to see. Running dmesg though did not notice anything weird.

Thanks!

Sounds like I can't help you unless I got rid of secure boot? If you
mean otherwise you'll have to forgive me, I'm clearly not following your
shorthand. I don't deal with this stuff often.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Timo Aaltonen]

I can't build signed packages.. so you can install fresh -23 from the
same place and not worry about the signed crap because you don't have
meta packages that need -23

but to fix that error you need to reinstall the stock linux-
image-*-4.4.0-22 packages

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Brian J. Cohen]

I think what the others are referring to is:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 linux-signed-image-4.4.0-22-generic : Depends: linux-image-4.4.0-22-generic (= 
4.4.0-22.39) but 4.4.0-22.39+bpo2 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a 
solution).

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Brian J. Cohen]

@tjaalton: Tried unsuccessfully to boot your kernel. I'm using disk
encryption and it never prompts me to decrypt the disk. Just keeps
outputting a warning about failing to connect to lvmetad (I didn't copy
it down).  I do get the same warning on other kernels that boot
correctly but only once.

  Plugging HDMI screen in causes system hang

Status in linux package in Ubuntu:

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Timo Aaltonen]

I still need test results from my kernel build, since that has what is
going to be in the next SRU kernel and if it's still broken then there's
something to be backported to core-drm (from v4.4..v4.6)

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Brian J. Cohen]

4.6.0-rc7 seems to have resolved the freezing issues I had on the Lenovo
T460s, including when modifying the resolution or launcher placement
after a suspend cycle.

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

[cement_head]

BTW, a handy-dandy GUI-based tool to have installed to test different
kernels is the GRUB-CUSTOMIZER package.  Please DO NOT uninstall the
"stock" 4.4.x kernel, you may to fall-back to it if the upstream kernel
doesn't work.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[cement_head]

@tjaalton

To manually install an upstream kernel I would need to install the
packages in purple (not blue) for an AMD64 machine?

  Plugging HDMI screen in causes system hang

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Mondane]

Since yesterday on

No LSB modules are available.
Distributor ID: Ubuntu
Description:Ubuntu 16.04 LTS
Release:16.04
Codename:   xenial


I have 

Linux 4.4.0-22-generic #39-Ubuntu SMP Thu May 5 16:53:32 UTC 2016 x86_64
x86_64 x86_64 GNU/Linux

But still, when I have booted my laptop (HP ProBook 650 G2 with HP
ProBook 650 G2) and hook-up a VGA monitor, Ubuntu freezes. Could it be
more code must be ported back?

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Brian J. Cohen]

Running 4.4.0-22.38 on a Thinkpad T460s, I'm now able to attach an
external monitor via HDMI without the machine freezing in the manner
described by others. However, I can still make it freeze if I enable (in
System Settings > Brightness & Lock) 'Turn screen off when inactive
for:' and let the screen turn itself off via the timeout specified. When
I awaken the screen by, say, moving the mouse, I find two things have
happened:

1. The launcher has reverted its placement to the built-in display (I
had changed in in 'Displays' to live on the external display.***

2. The system will lockup hard if I move the mouse between displays.


*** This also happens when I first attach the external display; my preference 
for launcher placement is not being remembered, unlike my resolution settings, 
which are.

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[SamF]

I'm also getting this problem. It seems, as others have said, to be
triggered by moving the mouse from laptop screen to external monitor or
vice versa.

Re: [Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[jnshey]

In order to boot, I need to set acpi=off when I use 4.4.8, which solves the
external monitor issue. However, I am not able to shut down my computer
without pressing the physical button. Any ideas?

Kernel 4.4.8  solved my issues completely! I can plug any monitor before
or after boot using DP or HDMI. I also have multiple window managers

[Kernel-packages] [Bug 1559308] Re: Plugging HDMI screen in causes system hang

[Koen Roggemans]

In comment #8 it's mentioned that it is not fixed in 4.4.0-22. I hope that's a 
typo :-(
I have a crashing 4.4.0-21 (Thinkpad 13 with an Intel N3150 processor / HD 510 
Graphics) 
My workaround is installing kernel 4.6RC6

  Plugging HDMI screen in causes system hang

Bug description:
  I have a 4K UHD laptop screen and am running Ubuntu Gnome 16.04 Beta1
  using 4.4.0-13-generic and the Nouveau drivers.

  If I plug in an external HDMI monitor (FHD) either into either HDMI
  port (there's one on the machine and there's one available via a usb
  3.1 extra adaptor) then the whole system hangs, completely
  unresponsive and needing a hard reboot. Before hanging the 2nd display
  gets an image as expected, but the laptop's screen flashes randomly,
  sometimes you see weird artifacts. Then the hang comes.

[Michael G.]

@tjaalton: Could you please elaborate what that means? Does that mean
that a fix will be available via the ubuntu updater soon? Or do we have
to wait till 16.10? Thanks!
