Bug description:
  [Impact]

   * When a TV is power-cycled, it is no longer detected as an available 
display.
   
   * The root issue is in xfce4-settings: xfsettingsd.
   
   * The related patch correctly handles the NULL mode the TV enters when 
powered off.

  [Test Case]

   * Connect a TV to a computer running xfce4-settings 4.12.0, this can be in a 
single configuration or dual-monitor.
   
   * Power the TV off.
   
   * Power the TV on.
   
   * Expected: TV powers on and remains connected as an available display.
   
   * Actual: TV powers on and is not connected or detected.

  [Regression Potential]

   * Regression potential is minimal: The associated patch targets this
  very specific scenario and behavior, and does not interact with the
  rest of the codebase.

  [Original Report]
  I had an HTPC with Mythbuntu 12.04 installed. Upon upgrading a new behavior 
that if the TV is power cycled it no longer detects a link with the HTPC.

  When this happens I can find in the xorg log that there is an
  accompanying log item:

  [ 39829.509] (II) NVIDIA(0): Setting mode "NULL"

  After debugging with NVIDIA at
  https://devtalk.nvidia.com/default/topic/729955/linux/tv-stops-being-
  detected/ we've deteremined it's a X client that reacts to the RANDR
  events causing the mode to be set to NULL.

  Working through the list in an Xfce environment, the culprit is
  xfsettingsd. If xfsettingsd is running, it causes the TV to come up in
  a NULL mode. If it's killed, it remains in the mode it was previously
  running in.

  Until this is fixed, this behavior can be worked around with a simple shell 
script:
  ==
  #!/bin/sh
  #Fix TV state when HDMI link is lost.
  #By Mario Limonciello 

  OUTPUT="HDMI-0"
  BAD_MODE="1280x720"
  GOOD_MODE="1920x1080"

  for MODE in $BAD_MODE $GOOD_MODE; do
   DISPLAY=:0 xrandr --output $OUTPUT --mode $MODE
   sleep 2
  done

[Linux-traipu] [Bug 1308105]

[Vincentiwilliam]

Haven't had any problems since installing the patch from #53. I plan to
upgrade Arch next weekend but haven't seen a new release of
xfce4-settings (4.12.0-3).

[Drew Lustro]

Wow... thank heavens. I can also very that the patch from Comment #53
has solved this bug that has been driving me nuts for weeks. I would
lose my entire X session every single day as soon as the screen
blanked... quite troublesome when you're trying to make linux work as
your daily drive, haha.

I had to learn how to patch a .deb file properly in the process, but
that was worth it too.

Cannot thank you enough, @jkampe68

[Linux-traipu] [Bug 1308105]

[Jkampe68]

I see one issue in the patch;

When enabling the crtc it _unconditionally_ sets the output crtc (preferred) 
mode, rotation etc. properties.
In multimonitor setups this likely leads screens to appear mirrored after power 
cycle (see comment #63 and #64)

The patch should be improved by reading/restoring the crtc output
properties from saved xfconfig. I simply was not up to the task to write
that code, maybe someone can contribute?

[Bluesabre-1]

I'm really impressed, thanks to the persistence with trying to find a
solution to this bug.  As several of you have mentioned, the patch in
#53 / #54 (courtesy of jkampe68) seems to resolve the issue. I have
tested this patch myself, and while not being able to reproduce the
original issue, I have verified that there do not seem to be any
regressions with this patch.

I have committed this change here:
https://git.xfce.org/xfce/xfce4-settings/commit/?id=2233f20a7ec6d7cb7dcc5752d62d98e37d9c21ad

I'm planning to do a new release including this patch shortly. HUGE
shout out to everyone that helped figure this one out!

I just upgraded Arch (-Syu) with xfce4-settings ignored in pacman.conf, then 
upgraded xfce4-settings from the aur using James' 
[url]https://aur.archlinux.org/packages/xfce4-settings-blank-screen-fix/[/url]
and all is well (tested KVM switch, tested turn off monitor), thanks James!

[Linux-traipu] [Bug 1308105]

[graysky]

In troubleshooing with ToZ in the forums, it seems as through this bug
is related to bug #12480 as well.  The patch from comment #53 seems to
be allowing my monitor to wake from suspend under the 4.4.x series of
kernels. I will preform more tests before calling this solved, but
wanted to document this in the ticket.

[Linux-traipu] [Bug 1308105]

[Luuk van der Duim]

On Linux Mint 18 xfce, I too got bitten by this bug.
After power off / power on, the monitor reports 'no signal'.

Intel Integrated Q45/Q43 Graphics (Dell Optiplex 780 USFF)
DisplayPort <--> DVI-D cable
Acer V243HL LCD Monitor (1920x1080 @60Hz)


I applied 'Enable crtc if it is disabled after power cycle' patch as provided 
in comment #53 by jkampe68 to the source package of xfce4-settings 
(4.12.0-2ubuntu1)

This fixed the issue. Thank you jkampe68.

I sincerely hope this patch or an adaptation that fixes the problem
accordingly will find its way into the xfce4-repository.

Thanks in advance!

Luuk

(In reply to jkampe68 from comment #68)

I suggest that we close this issue and create a new for the mirrored-
after-power-cycle.

[Linux-traipu] [Bug 1308105]

[Travis-o]

Similarly I keep losing my configured resolution of 1280x720, with the
system defaulting back to 1920x1080 every time (which looks rubbish on
my crappy monitor).

Manually running "xfsettingsd --replace" is a workaround, but not ideal.
All progress though, it's still much better than rebooting every time.
Thanks a ton for getting us this far.

Hi - sorry to comment on an old closed bug, but has anyone ever reported
the remaining problem (monitors mirrored after wake) as Natanael Copa

Probably had 2 dozen or more suspend/wake cycles using the patch from
comment #53 under linux v4.4.6 and it xfce4 is behaving as it should
waking the monitor.  If the patch as-is is grammatically correct, etc. I
would recommended applying it to xfce4-settings.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Dion Bonner]

This is affecting me on Mythbuntu 16.0.4.3 - with all updates applied as
of 10.09.2017.  Machine is an Intel NUC NUC6CAYS.

Display is a Panasonic TV connected via HDMI.

As with other users above running xrandr --output 'DP-1' --mode
'1920x1080' brings the display back to life, as does restarting X11.
The problem can be cured by killing xfsettingsd.

dmesg and Xorg.log (concatenated together) attached so that you can get
a sense of the hardware involved.

Sorry not sure whether this issue is Ubuntu specific or whether the bug
belongs upstream with the XFCE guys.  Happy to help in any way I can.

  I had an HTPC with Mythbuntu 12.04 installed.  Upon upgrading a new
  behavior that if the TV is power cycled it no longer detects a link

  After debugging with NVIDIA at
  https://devtalk.nvidia.com/default/topic/729955/linux/tv-stops-being-

  events causing the mode to be set to NULL.

  Working through the list in an Xfce environment, the culprit is
  xfsettingsd.  If xfsettingsd is running, it causes the TV to come up

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Anna Thomas]

Running Xubuntu 16.04.1 with all updates applied as of 31/01/17 this bug
affected me when using the HDMI port of a Braswell chipset Shuttle
XS36V5. When resuming my Samsung TV from standby the HDMI wouldn't wake
up and thus no picture. It was the only display device attached. Tried
various combinations of power management settings in UEFI/XFCE/TV to no
avail, as well as a different HDMI port on TV as well as different HDMI.

Upon a 'sudo reboot' from SSH or by pressing the power button on the
shuttle (had power button set to 'shutdown' instead of 'ask') the TV
would wake up within a second or two and show the shutting down logo.

Consulted your Freenode IRC channel, Flocculant suggested applying:

https://launchpadlibrarian.net/269857837/xfce4-settings_4.12.0-3ubuntu1_amd64.deb

Which i did with 'dpkg -i xfce4-settings_4.12.0-3ubuntu1_amd64.deb &&
apt-get install -f' and this fixed it. Petition to get this fix applied
to a SRU for 16.04 thanks <3

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Stefan Fleischmann]

Note that there is a Ubuntu package of 4.12.1 available now
http://packages.ubuntu.com/zesty/xfce4-settings which can be installed
at least without dependency issues on Ubuntu 16.04.

The upstream commit that fixes the issue is here
https://git.xfce.org/xfce/xfce4-settings/commit/?id=2233f20a7ec6d7cb7dcc5752d62d98e37d9c21ad.

As mentioned in the upstream bug report: "[...] one issue in the patch;
when enabling the crtc it _unconditionally_ sets the output crtc
(preferred) mode, rotation etc. properties". Anyway it was decided to
merge the patch and address that issue in a new bug #. So maybe the best
way is to do the same here, i.e. mark this as fixed in zesty and apply
the patch in xenial and yakkety. And create a new bug for the lost
screen resolution and other settings.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Bengt Nilsson]

I tried xfce4-settings 4.12.1-11 as mentioned in #133 and indeed it "works", X 
does not crash.
However, the set screen resolution is lost. When I turn on the screen again, 
the desktop defaults to the highest possible screen resolution. 
In my case, it means that my desktop menu bar and docky are placed outside the 
screen bounds, tricky to reset.
Better than it was before, but not quite there yet.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Patricio]

I downloaded xfce4-settings 4.12.1-11 as stated in comment #130 but for
my i386-based xubuntu 16.04 from
https://packages.debian.org/stretch/i386/xfce4-settings/download

This solved it for me.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Aaron Whitehouse]

Jonathan,

Given the latest version of xfce-settings (4.12.1) was easy to install
and fixed all of my issues (see comment #130 above), it would be
interesting to know whether this also fixed your problem.

Kind regards,

Aaron

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Jonathan Boler]

I also installed
http://ftp.uk.debian.org/debian/pool/main/x/xfce4-settings/xfce4-settings_4.12.1-1_amd64.deb
but my 2nd monitor doesn't come back on after it's entered power-save
mode when I move the mouse which does turn my primary laptop display
back on.

No combination of xrandr commands or switching to the console with CTRL-
ALT-F1 brings it back on. The only thing that works is to power cycle
the monitor which causes the display setup to switch back to single
display mode. Then I have to go re-configure the dual display setup
which is really annoying because I have to move all my windows back to
their correct positions on the 2 displays.

I've tested my external monitor on windows and it always comes back on
immediately even after entering the same power save mode so it's not an
issue with the monitor.

Interestingly when I use the displayport over USB-C pass through it all
works correctly. It's only with HDMI that the problem occurs.

I'm using a Dell Precision 5510 laptop with Intel Graphics enabled and
the nvidia graphics disabled on Xubuntu 16.04.1 with all updates
applied. I've also tested this with the same results on Ubuntu 16.10
with all updates applied.

xrandr shows it's still sending the signal to the external HDMI display
even though the display is still in power saving mode:

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Aaron Whitehouse]

I have an ASUS Z170M-Plus Mobo with an Intel Core i3-6100T, Intel HD 530
graphics and a Samsung TV connected through HDMI, running Mythbuntu
16.04.

I had the issue that when I turned the TV off and then back on again, the TV 
would say "No Signal" and I would have to run 
$ sudo service lightdm restart
to get it to work again.

Based on Alexandre's comment #128, I installed xfce-settings 4.12.1 from here:
https://packages.debian.org/stretch/amd64/xfce4-settings/download
http://ftp.uk.debian.org/debian/pool/main/x/xfce4-settings/xfce4-settings_4.12.1-1_amd64.deb
and installed it on my Mythbuntu 16.04 installation. To my surprise, I didn't 
have any dependency issues, it all applied without problems and now the problem 
seems fixed! I can turn the TV off and on again and the picture comes back as 
expected.

Great work all in getting this sorted.

[Patricio]

Thanks for that!
I think I'll keep waiting for the patched version to come out for my distro 
(32bit Xubuntu 16.04) as I'm really trying to avoid installing dev tool and 
compiling from source... I guess I'm just too old and grumpy now and prefer to 
spend time using my computers than fixing them. I already filled my quota of 
applying manual patches for things to just work in the 90's :D.

Anyway, I really appreciate the effort many of you guys put into making
my life easier with great, open software.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Alexandre ACEBEDO]

Hi!
The XFCE4's maintainer claimed to have merged the patch for this bug here:
https://bugzilla.xfce.org/show_bug.cgi?id=11107#c67 on 2016-08-12.

A new version of xfce-settings (4.12.1) has been released on 2016-09-15
so we can assume that the fix is integrated in the release.

Note that the patch is not the same as the one I've linked in comment
#107. I still have to test the new version.

Note also that the 4.12.1 version was not integrated in ubuntu 16.10 so
we still have to recompile and install it manually :(

Hi.
This affects me too.
I'm looking for what some other users refer to as "Alexander's patch" but I 
can't find it.
Additionally, I see the post numbers jump fro #2 to #41... How can I see the 
other posts? Perhaps the patch was posted there?

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Manuel Widmer]

As another workaround it is possible to disable the hotplug events in xorg conf.
here the steps:
switch to tty (crtl + alt + f1) and log in.
sudo service lightdm stop
sudo Xorg -configure   # this creates an xorg.conf and displays where it is 
stored
sudo cp /path/to/xorg.conf.new /etc/X11/xorg.conf
sudo vim /etc/X11/xorg.conf

then add to the "Device" section: 
 Option "UseHotplugEvents" "false" 

save and quit and restart lightdm:
sudo service lightdm start

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Brax]

The patch by philmanjaro works for me too by following instructions by
Alexandre ACEBEDO (aacebedo) from 2016-01-25, on a braswell system
(N3150 - Zbox CI323)

One thing though, I still have an issue if the TV is turned off when the
PC is booted initially, xrandr will give me the proper info and tell me
the screen is connected once I power it on, but xfce will still show it
as Disabled (by connecting with x11vnc), I'm not sure if it's related or
not

xrandr -auto sometimes fixes it but not always I sometimes have to
reboot the system with the TV powered on for it to start working again

[Ian Young]

The patch in comment #53 works for me too, meaning that the desktop
remains visible after power cycling my receiver.  However, the MythTV
frontend disappears (but the process is still running, according to ps).
mythfrontend.log doesn't provide any clues as to what is happening at
the time the receiver is turned off, either.  I guess I could upgrade to
Mythbuntu 16.04 but I'm expecting to encounter new problems then, such
as no more 32-bit Chrome.

[Drew Lustro]

OK. This has been driving me nuts for weeks. I would lose my entire X
session every single day as soon as the screen blanked... quite
troublesome when you're trying to make linux work as your daily drive,
haha.

*Confirmed fix* w/ the patch suggested on xfce's bugzilla:
https://bugzilla.xfce.org/show_bug.cgi?id=11107#c53

Download the xfce4-settings source, apply the patch, increment with a
non-maintainer version number (for no future apt-get conflicts once this
gets an official fix), and reinstall your patched xfce4-settings.

I had to learn how to patch a .deb file properly in the process, but
that was worth it too.

GPU: GTX 970 over DisplayPort 1.2
Monitor: Dell P2715 (4K@60Hz, hardware rev A03)

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Chuck McManis]

Ok I have confirmed that the patch in #115 (Saved the Patch by jkampe68
(http://bug-attachment.xfce.org/attachment.cgi?id=6590) as .patch file.)
fixes the issue on NUC derived systems (Intel graphics, I've got a
NUC5i7RYH and a Gigabyte BRIX) where the screen attached to the display
port output does not come back on when power is re-applied to the
monitor. The next step is validating that the screen can recover after a
"sleep state" which has been initiated by light-lock.

I pulled the git repo applied the patch, ran autogen.sh then make, then
make install. Rebooted and verified the new settingsd was running (

cmcmanis@charliehorse:~$ xfsettingsd --version
xfsettingsd 4.12.0git-56abfbd (Xfce 4.12)

Copyright (c) 2008-2011
The Xfce development team. All rights reserved.

Please report bugs to .
cmcmanis@charliehorse:~$ 

Power cycled the monitor, and where previously this would always cause
it to not come back, it now returns. System is Xubuntu 16.04 otherwise
vanilla install.

[Chuck McManis]

I have confirmed that this patch allows my NUC derived systems to
recover the display when the monitor is switched off and then switched
on again. This for a NUC5i7RYH and a Gigabyte BRIX (GB-BXi5H-4200)

Scratch that, forgot to autogen.sh first, did it earlier but did not
repeat after resolving the last dependency. So not it compiled, on to
testing.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Chuck McManis]

Trying to implement the suggestion in #115, I've got the git repo from
xfce.org and applied the patch, did the configure which ends with:

Build Configuration:

* Installation prefix:   /usr
* Debug Support: full
* Xrandr support:yes
* UPower support:no
* Libnotify support: no
* Xcursor support:   yes
* Xorg libinput support: no
* Embedded settings dialogs  no
* Sounds settings supportno
* Libxklavier support:   yes
* Mime settings (gio-unix):  yes

But attempting a build gives the error:

make[4]: Entering directory 
'/home/cmcmanis/src/xfce4-settings/dialogs/appearance-settings'
  CC   xfce4_appearance_settings-main.o
main.c:44:34: fatal error: appearance-dialog_ui.h: No such file or directory
compilation terminated.
Makefile:667: recipe for target 'xfce4_appearance_settings-main.o' failed

So presumably there is a missing step here somewhere.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Vaughan Harper]

Just a minor point: Glen pointed out in comment #86 that the curl
command to get the patch files doesn't work.

I've done some playing around. For some reason 'curl
https://bugzilla.xfce.org/attachment.cgi?id=5681' doesn't work - but
'curl -L http://bugzilla.xfce.org/attachment.cgi?id=5681', which follows
the 302 redirect from 'http://bugzilla.xfce.org/...' to
'https://bugzilla.xfce.org/...', does work.

So it's possible to get the patches by issuing:

curl -L http://bugzilla.xfce.org/attachment.cgi?id=5681 > alexander-patch.diff
curl -L http://bugzilla.xfce.org/attachment.cgi?id=5723 > sean-patch.diff

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Andy Wood]

Reproducible on HP Pavilion SE a6655f, AMD x64, with Asus brand Geforce GT-220 
(ENGT220) video card, only connected output is HDMI to surround receiver, then 
HDMI to Panasonic LED TV.
Unused workaround from comment #22 (disable xfsettingfsd) and has been solid 
since. I switched inputs on the TV away from the surround to a digital cable 
box, watched a little TV, then back without issue. I turned off TV and 
surround, turned back on, and I can still see the output from the HP. 

Mythbuntu 14.0.4 LTS (fresh install of 14.04.4 actually).

A side-effect was that sometimes the mouse pointer would also disappear
if I switched away and back again. I'll be watching that problem closely
on this HP PC now that I've worked around the current problem.

The patch in #53 is working for me. Arch Linux 4.3.3.2-ck. Asus Radeon
R7-240 video card (using the hdmi port), Asus M5A88-M computer. I can
now switch via k-v-m to other pc's, can turn off power to monitor for
extended periods and all resumes when power is back on or k-v-m is
switched back to the Arch pc (other pc's are vga).

[Linux-traipu] [Bug 1308105]

[Jkampe68]

As suggested in comment 49
I think proper solution is enable crtc upon reconnection IF it is disabled.

Here is a prototype for patch - I'm hoping maintainer (Sean?) 
can suggest "correct code" to enable crtc.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Alexandre ACEBEDO]

I have exactly the same issue on 15.10 with an intel card.
philmmanjaro on github has published a patch to solve the issue. Just applies 
the patch on xfce 4.12 source code
The workaround to fix this is the following:

$> sudo apt-get install xfce4-dev-tools libexo-1-dev libgarcon-1-0-dev 
libxfce4ui-1-dev libxklavier-dev
$> git clone git://git.xfce.org/xfce/xfce4-settings
$> git clone https://github.com/manjaro/packages-extra.git
$> cd xfce4-settings
$> git checkout xfce4-settings-4.12.0
$> patch -p1 < ../packages-extra/xfce4-settings/hdmi-power-cycling.patch
$> ./configure --prefix=/usr --enable-pluggable-dialogs --enable-libxklavier 
$> make
$> sudo make install
$> sudo reboot now

seeing this in 16.04 daily xubuntu

didn't get anywhere with the script in the LP bug report, nor trying to

I am though getting success here using the one-liner (though sleeping

[Linux-traipu] [Bug 1308105]

[Vincentiwilliam]

I still get this in xfce4-settings.4.12.0-3 when I shut off the monitor via its 
power button, or switch to another pc via a K-V-M switch. I'm unable to resume 
the display when switching back to my Linux pc or turning the power back on. I 
have to run 4.10.1-1. For a while I used the 4.11.3-3 fix from Manjaro but that 
doesn't work now either since last -Syu. I'm running Archlinux 4.3.0-1-ck on an 
Asus M5A88-M mobo, with on-board Radeon 4250 graphics using the HDMI port. The 
HDMI is directly connected to an Asus VS247 lcd monitor. The K-V-M only 
switches the keyboard and mouse from the Linux pc, the other pc's it also 
switches the VGA as they are connected to the monitor VGA (the monitor default 
is HDMI so I manually switch the monitor by its selector button to VGA for the 
VGA pc's). I have to remote into the Linux pc and do a normal reboot in order 
to get the display to turn on else use the power button on front of the Linux 
pc :(.
Not sure where to look to troubleshoot. Thank you for your consideration.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Ivan Kozik]

I have a Viewsonic VX2475Smhl-4K attached with a DisplayPort cable to a
Gigabyte GTX 970 (nvidia-358 driver, ASUS Z97-A, UEFI boot with CSM
disabled), and it requires `xrandr --auto` after being power cycled.
That's easy to set to a keyboard shortcut when logged in, but harder in
xflock4.  Even less amusing, Linux text VTs don't work until an `xrandr
--auto` in an X session.

There were reports that non-VESA-compliant DisplayPort cables that wire
pin 20 (DP_PWR) cause this problem, but I checked my Cable Matters cable
with a multimeter and it does not wire pin 20.

Microsoft has a page about this problem: https://support.microsoft.com
/en-us/kb/2625567

[Erik Hovland]

Adding my me too. I have a ECS Liva X with an intel graphics chip. When
I turn off my Samsung TV the screen goes away. I added the suggestion
above (killall xsettingsd) to the /etc/mythtv/session-settings and was
able to confirm that it does workaround the problem.

[Linux-traipu] [Bug 1308105]

[Newacct407]

Looking at Sean's comment of 2015-02-19, it appears that a functional
patch is still being sought.  I am experiencing the problem of the
display not coming back when it is reconnected.  I'm posting this in
hopes that it assists the maintainers of the code in resolving the
issue.  With the 4.12 branch from git, I was able to reproduce this bug
with just a regular desktop (non HDMI) by disconnecting and reconnecting
the monitor.  When the monitor was reconnected, the screen does not
resume.

In the xfce_displays_helper_screen_on_event function in the top section
it has the condition of the disconnection of the monitor.  In that
section it is calling a forced disable of the crtc via

  crtc-mode = None;
  xfce_displays_helper_disable_crtc (helper, crtc-id);

However, in the else condition below where it is adding in new outputs,
the crtc is still in a disabled status when this gets executed after the
cable has been reattached.  (mode = None, width=0, etc)

I think that the proper solution is to get the crtc re-enabled/refreshed
upon reconnection and I'm hoping that those that actually know this code
would know how to do this (I tried a couple of options across various
functions but they did not work).

The interim hack solution that seems to work for me is to comment out
the code that is disabling the crtc.  This doesn't seem to spawn
additional displays but may other regression problems.  And since it is
a true hack rather than a correct solution, I'm not attaching it as a
patch.

Hope this helps, let me know if testing is needed or if you can point me
to the proper method of getting the crtc information refreshed.

[Linux-traipu] [Bug 1308105]

[M-zdila]

On my system (Linux bono 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1
(2015-05-24) x86_64 GNU/Linux) the issue appeared only cca 2 weeks ago.
I don't know which package update (Debian Testing) caused it.

Everytime the monitor blanks it can't resume.

My workaround is to have this code running:
while true; do xrandr -d :0 --output HDMI1 --mode 1920x1080; sleep 10; done

My display card:
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen 
Core processor Graphics Controller (rev 09)

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Ernst Sjöstrand]

My best solutions to the MythBuntu/XBMC/Kodi usecase:

1) Run a MythBuntu/XBMC/Kodi-session without any desktop at all! They're in 
/usr/share/xsessions/
for running completely standalone.

2) Running a really minimal WM that doesn't try to manage screens at all like 
Openbox. Works
well with Steam big picture mode.

[Adam Kaminski]

I am currently experiencing this issue with a foxconn d180s j1800
motherboard and Xubuntu 15.04. After turning off the TV and receiver I
do not receive any video when turning them back on.  Running the script
fixhdmi.sh posted above or 'xrandr -d :0 --auto' seems to fix the issue.
I just need to figure out how to trigger when TV turns back on.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Arjen]

You could probably just use 'xrandr --auto', at least that worked for
me.

I have actually now a different 'fix', by simply never having the system
notice the hdmi-link goes down. I used this wiki-page to fix that for my
Intel Haswell-cpu graphics.

https://wiki.archlinux.org/index.php/Kernel_mode_setting

My final cmdline is now this:
video=HDMI-A-1:1920x1080@60e 
dmr_kms_helper.edid_firmware=HDMI-A-1:edid/tv-edid-data.edid

The tv-edid-data file is located in /usr/lib/firmware/edid/ and was derived via 
'get-edid'. It actually also seemed to work with the built-in '1920x1080.edid' 
(saves you retrieving it from your receiver, but I thought it a bit more save 
to have the actual edid).
Just supplying the video-parameter wasn't enough in my case, it failed to 
actually set the resolution to 1920x1080 (and used 1024x768 instead). Adding 
the edid-data fixed that (it may even be sufficient to only force-load the edid 
data).

The reason this works is not because it fixes the issue, but because it
prevents the hdmi-link from ever going down - as far as the kernel is
concerned.

I have been having this issue on my 14.04 install for a while now (probably as 
long as Mario), i have been using my rPi and a button to run a command over ssh 
to fix it 
DISPLAY=:0.0 xrandr --output HDMI-0 --auto

i upgraded me and my dad to xfce 4.12 and now he has the issue ga-a55m-ds2 
motherboard and a AMD A6-3500 APU
he is running xubuntu 14.04 w/ linux 3.16.7 w/ xfce 4.12 (open source drivers, 
NOT fglrx/catalyst)
he is using DVI on a HP 2009M monitor
this command restores the display for him
DISPLAY=:0.0 xrandr --output DVI-0 --auto
he seems to have this issue wen the power manager turns the display off and the 
monitor goes into standby

[Linux-traipu] [Bug 1308105]

[Bigwoof1234]

Hi Sean,

interesting. I have never tried to configure the monitor as this is my
projector display and not my laptop.

This is wierd as the bug you mentioned would suck for laptop / PC use
where you plug in and configure external displays somewhat regularly but
the bug that is the point of this bug report is terrible for anyone
using a projector or LCD display that is attached to a media PC and
switched off fairly regularly.

I guess I'll just continue using my patched version until a suitable
fixes all bugs version is written.

Thanks for the explanation for why the patch has not been included yet
b.t.w. It was very informative!

Raj

[Linux-traipu] [Bug 1308105]

[Bigwoof1234]

so the original bug of the display resetting to NULL has *not* been
fixed in the latest git version.

I left it for a day, came back and the display was blank when I turned
on the projector.

I have applied Alexander's 1 line patch and I'm testing that now. But
the git version has *not* fixed the problem.

Someone else has reported the same issue with the git version in the
ubuntu version of this bug report btw

https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-
drivers-331/+bug/1308105

see the last comment at the bottom

can we please include the 1 line patch to the master repo?

Thanks,

Raj

[Linux-traipu] [Bug 1308105]

[Bluesabre-1]

I would add the one-line patch, but then every monitor event triggers
the new monitor signal since all previously known monitors are now
forgotten.

To see this bug in action, enable the setting Configure new displays
when connected, then manipulate the monitors with the settings dialog.
Move them, turn them on/off, click apply.

You'll quickly find many many display settings popping up.

So while this patch fixes this bug for you, it also creates a new bug
for everyone. Please continue to explore and provide additional patches.
It's difficult to provide a proper fix when the original issue does not
affect me or Simon, the other active maintainer of the display
settings..

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Glen Dragon]

For those trying the above commands...  the curl to get the patch files is 
likely not working.
I'm not motivated enough on curl to figure out the problem, but i was able to 
copy/paste with a browser.
If you are unsure, look at the patch files, git diff, the output of patch, 
etc...


For me the latest git did not fix the problem.
Sean's (updated) patch also did not fix the problem.
Alexander's patch *did* fix my problem.

My use case is with a single display attached to a A/V receiver.  Turning the 
receiver off, and back on did not come pack.  
Using alexander's one liner, it works great.

IMHO, this is a big issue, and i'm shocked that it's not been rectified
yet.

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[fkervin]

I've spent a good amount of hours researching and making tests,
unfortunately I can't make it work and I'm really desperate, so I'd
really thank any help.

I hope someone can lend me a hand (mainly on the procedures of patches of 
alexander and sean, I can't make them work).


The script of first solution works (in my case replacing HDMI-0 with HDMI1), I 
create it in ~/fixhdmi.sh and chmod 755 it.
 
The question here is automating the process, and in this I've not been able to, 
It only works running script manually from terminal (I've no try to make a 
shortcut, it's not valid for my needs) :(

I even added a wait time before the process (since the TV takes some
time in beign ready I thought it could help) and a message after with
zenity:

[code]#!/bin/sh
#Fix TV state when HDMI link is lost.
#By Mario Limonciello email address hidden
sleep 10
OUTPUT=HDMI1
BAD_MODE=1280x720
GOOD_MODE=1920x1080

for MODE in $BAD_MODE $GOOD_MODE; do
 DISPLAY=:0 xrandr --output $OUTPUT --mode $MODE
 sleep 2
done
zenity --info --title=HDMI --text=fixhdmi.sh has been executed
[/code]

I've found a few entries explaining the procedure of udev, so I've
create a the file /etc/udev/rules.d/hdmi.rules with this content

[code]KERNEL==card0, SUBSYSTEM==drm, ACTION==change,
RUN+=/home/fkervin/fixhdmi.sh[/code]

I also tryed:
[code]SUBSYSTEM==drm, ACTION==change, RUN+=/home/fkervin/fixhdmi.sh[/code]

I tried another ones I don't remember...

The result without the udev entry is no signal message, with it I have
cursor on screen over black for a seconds but then dissapear and no
signal message again. It makes me think that

the udev could be working on TV disconnect but not on connect (only an
idea). Later when I tried the alexander's mod I had the same effect,
(cursor and blank screen), I don't how it there is any relation.

I've try udevadm in a power-off/power-on of the TV, having this result:

[code]
fkervin@fkervin:~$ sudo udevadm monitor
[sudo] password for fkervin: 
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[121.525065] change   /devices/pci:00/:00:02.0/drm/card0 (drm)
UDEV  [135.590008] change   /devices/pci:00/:00:02.0/drm/card0 (drm)
KERNEL[142.156140] change   /devices/pci:00/:00:02.0/drm/card0 (drm)
UDEV  [156.226634] change   /devices/pci:00/:00:02.0/drm/card0 (drm)
[/code]

I can't figure out how to make udev rule work :(

-

I've try to install Xfce 4.12 packages:

[code]
sudo add-apt-repository ppa:xubuntu-dev/xfce-4.12
sudo apt-get update
sudo apt-get upgrade
[/code]

It unfortunately doesn't solve the problem.

--

killing xfsettingsd makes it work, but since it interfere on the icons,
text and many elements, it's not appropiate.

--

In the option of installing an older xfce4-settings:

by adding the saucy mirrors to you sources.list, and running apt-get
update  apt-get install xfce4-settings/saucy or apt-get -t saucy
install xfce4-settings

I don't know what should I add to sources.list.

--

Alexander and sean's procedures:
I've try several times with no results, for example:

fkervin@fkervin:~$ sudo apt-get install xfce4-dev-tools libexo-1-dev 
libgarcon-1-0-dev libxfce4ui-1-dev

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[Alexander Schmidt]

With the current git-master (xfce4-settings
8adbd2e2463f5cc46c7ed94c0acf264155476268) and NO patches the issue does
not occur for me. That is, neither when powering my HDMI-connected
screen off and on again nor when physically disconnecting and
reconnecting it.

However, I cannot even reproduce the original issue anymore. Weird!

My current configuration:
Xubuntu 14.04 x64
Kernel 3.13.0-45-generic
Intel Core i5-4590S
Intel driver 2.99.911-0intel1
Monitor attached with a HDMI-to-HDMI cable

Things that indeed changed:
- new, different mainboard (the old one died some weeks ago due to a power 
supply voltage peak)
- new but identical CPU (died due to the same reason)
- upgraded packages from the official Xubuntu 14.04 sources (got no related 
PPAs or such, so it's just regular updates)
- new kernel version (probably does not matter)

Btw, my machine is not a laptop, so I'm down to 0 outputs when
physically disconnecting my screen (I kind of remember this being
relevant in the source code).

[Linux-traipu] [Bug 1308105] Re: Xfce resets TV mode to NULL when power cycled

[fkervin]

Hi Everyone,

I'm glad to have found this thread (Many thanks to ToZ in
forum.xfce.org): https://forum.xfce.org/viewtopic.php?id=9391

My problem is I read so many possible solutions that I really don't know
what to do. I have an intel onboard graphics card and if I turn off TV i
have blank screen when later I switch it on again (Xubuntu 14.04)

What is the procedure you reccomend me to do?  From last posts here it
seems to be a fixed releaded, how do I install?

I've make a recopilation of all the possible solutions I've read here:

FIRST - Use this script when problem happends:
==
#!/bin/sh
#Fix TV state when HDMI link is lost.
#By Mario Limonciello email address hidden

OUTPUT=HDMI-0
BAD_MODE=1280x720
GOOD_MODE=1920x1080

for MODE in $BAD_MODE $GOOD_MODE; do
 DISPLAY=:0 xrandr --output $OUTPUT --mode $MODE
 sleep 2
done
==

My question is: How can I run the script when HDMI link is lost if I've
no video signal?


SECOND - install gnome-settings-daemon and launch on system boot.
It seems too easy to be true, hehe, Do i try?


THIRD - killall xfsettingsd
In my case I can leave computer on with desktop on screen, so I can't do this 
on any program boot. Whose are the consequences of killing this application on 
system boot?
I've read it can causes an undesired problem, fonts are unreadable (could cause 
some problem with image quality)

FOUR - Using DVI cable instead of HDMI
I could use a DVI to HDMI cable, at last I can get sound from it, althought I'd 
prefer maintaining the DVI connection.

FIVE - downgrade xfce-settings to the 4.11.0 package from Saucy, and locked 
it at that version (4.11.3 causes the problem).
How can I do this?

SEVEN - Create xorg.conf and add those lines:
Option ConnectedMonitor DFP1
Option UseDisplayDevice DFP1

OR
   Option ConnectedMonitor DFP-0
   Option UseDisplayDevice DFP-0

to the devices section of /etc/X11/xorg.conf.

Only for nVidia cards

EIGHT - Install a patched 4.11.3 (from my PPA here: 
https://launchpad.net/~landronimirc/+archive/ubuntu/collection , includes 
fix_for_bug11107.patch).
The person who told this seems to not have solved with this procedure. How can 
I do this? I mean, How can I Install this patched version.

NINE - Sean's patch, fix_for_bug11107.patch
I don't know where to download it from or how to install, it seems to be 
explained in next option (TEN)

TEN - Alexander's patch, also Sean's, explained here:
For Ubuntu 14.04, this is how your you can build xfsettings with the patches:

sudo apt-get install xfce4-dev-tools libexo-1-dev libgarcon-1-0-dev 
libxfce4ui-1-dev
git clone git://git.xfce.org/xfce/xfce4-settings
cd xfce4-settings
curl https://bugzilla.xfce.org/attachment.cgi?id=5681  alexander-patch.diff
curl https://bugzilla.xfce.org/attachment.cgi?id=5723  sean-patch.diff
Choose a patch to Apply: patch -p1  patch
./autogen.sh  make  sudo make install
/usr/local/bin/xfsettings --replace

If you wanna to try other patch, first remove what's applied:
patch -R -p1  applied patch

After playing, remember to remove the installed xfsettings:
sudo make uninstall

How to test?:
- if I do `/usr/bin/xfsettingsd --replace` (4.11.3), then I can easily 
replicate the crash
- if I do `/usr/local/bin/xfsettingsd --replace` (GIT master with Sean's 
updated patch), the I can no longer replicate the crash

Problem: Mirror display is not available.




So I would really thank if someone can lend me a hand

Regards and thanks in advance

@Steve
I guess that Olivier, Alexander or Sean are more suitable to tackle this than 
me, all I did was to give some instructions and update the patch, so don't 
expect a patch from me any sooner.
I use a 27 display and 19 in extended mode(configured via NVidia Settings) 
and everything works smoothly, but as soon as possible, I'll give it a go(with 
and without patches) and see what happens while switching, plugging and 
unplugging them.

[Linux-traipu] [Bug 1308105]

[Liviu Andronic]

I would only suggest to prospective testers to first try out
Xfce4-Settings GIT (hence with Olivier's recent fix) with *no patch*. At
least here it fixes the issue, and maybe this addresses your concerns,
too.

Bug description:
  I had an HTPC with Mythbuntu 12.04 installed.  Upon upgrading a new
  behavior that if the TV is power cycled it no longer detects a link
  with the HTPC.

  When this happens I can find in the xorg log that there is an
  accompanying log item:

  After debugging with NVIDIA at
  https://devtalk.nvidia.com/default/topic/729955/linux/tv-stops-being-

  events causing the mode to be set to NULL.

  Working through the list in an Xfce environment, the culprit is
  xfsettingsd.  If xfsettingsd is running, it causes the TV to come up
  in a NULL mode.  If it's killed, it remains in the mode it was
  previously running in.

[Steve Dodier-Lazaro]

Raj,

Thanks for clarifying. There might have been several sources of crashes
in the same report.

Could the people who commented on this report test whether
Xfce4-Settings git (hence with Olivier's recent fix) + Alexander's patch
work well for them?

Olivier, André: would you like to take ownership of this bug and push
whichever additional patch is required?

[Bigwoof1234]

i'll test the latest git version without any additional patches early
next week when I get back home. I'll report what I find after a day or
two of testing (the bug only manifests when the display has been off for
quite some time)

Thanks,

Raj

[Bigwoof1234]

Hi,

just wanted to point out that Sean's patch did *not* fix the screen
disappearing issue for me but the one liner from Alexander did.

Was a different patch apply to the main tree to fix the original reason
for this bug report? I'm willing to test the latest version, but I can
only do it next week at the earliest.

[Linux-traipu] [Bug 1308105]

[Liviu Andronic]

As for the xfsettingsd crash, I noticed that with current master I was no 
longer experiencing the crashes. So I did some GIT bisecting, and it turns out 
that I can reproduce the crash with: 
http://git.xfce.org/xfce/xfce4-settings/commit/?id=5a7f55a049147320adb8e2dc8495d6f868c4d6ac

But I get no more crashes with: 
http://git.xfce.org/xfce/xfce4-settings/commit/?id=404d982f2936a58649423642956be563982b2ffa

It seems to me that Olivier has inadvertently fixed this issue... Just
to confirm, I do NOT get xfsettingsd crashes when using master and my
usual test case. As far as my setup is concerned, this issue is fixed.


=
So what remains to be addressed is the disabled `Mirror displays` option 
introduced in 835671ad8db9bcaed4ec3d53753b7f9a8b4610a7. Should I open a 
separate ticket on this issue?

[Andreldm1989-j]

@Jesse
If everything goes well, this fix is going to be on Xfce 4.12, the question is 
if Xubuntu is going to ship it in 15.04.
You can also build it by yourself or use a PPA, maybe 
https://launchpad.net/~xubuntu-dev/+archive/ubuntu/xfce-4.12.

[Linux-traipu] [Bug 1308105]

[Steve Dodier-Lazaro]

Glad to hear it's fixed for you. Looking at the two commits,
XfceOutputInfo *output was probably unitialised, causing a NULL check to
be ignored and a SEGFAULT.

Thanks for this thorough testing and debugging, Liviu. I'll close this
issue, please do open another report for your Mirror Display issue, and
mark it high -- I've spotted some variable initialisation bugs in that
code too.

[Linux-traipu] [Bug 1308105]

[Liviu Andronic]

As far as fixing the issue goes, it's very simple:

- if I do `/usr/bin/xfsettingsd --replace` (4.11.3), then I can easily 
replicate the crash
- if I do `/usr/local/bin/xfsettingsd --replace` (GIT master with Sean's 
updated patch), the I can no longer replicate the crash

I think the patch is effective at addressing the issue.

As for the disabled `Mirror displays` option, if I remove the stock
xfce4-settings and only keep the /usr/local/bin installation, then the
issue persists: when I connect the HDMI cable, the `Mirror displays`
option is disabled (see attached screenshot). I'm not sure how else to
test this...

  I had an HTPC with Mythbuntu 12.04 installed.  Upon upgrading a new
  behavior that if the TV is power cycled it no longer detects a link

  events causing the mode to be set to NULL.

  Working through the list in an Xfce environment, the culprit is
  xfsettingsd.  If xfsettingsd is running, it causes the TV to come up
  in a NULL mode.  If it's killed, it remains in the mode it was
  previously running in.

Hi Liviu,

Let us know in a few days if the bug is fixed with the patch, and if no
side effects were found, so we can release it in time for 4.12.

Thanks.

[Linux-traipu] [Bug 1308105]

[Liviu Andronic]

Thanks a lot André! And thanks a lot for the instructions; although I
know most of them individually, stringing them all together wasn't
immediately obvious.

I've tested Sean's updated patch and I'm happy to report that it seems
indeed to solve the `xfsettingsd` crashes. I will test it for a couple
more days to make sure that all is OK, but so far looks very promising!
I'll report back if I'm still hitting trouble.

(The only nagging issue was that after `make install`---hence having
both /usr/bin/xfsettingsd and /usr/local/bin/xfsettingsd---for some
reason the Mirror display option was greyed out. I suspect it's some
issue with having both binaries installed at the same time, but I can't
say.)

I tested Alexander's patch, and although I'm not yet sure if it helps
with the xfsettingsd crash, the approach is buggy. First I notice that
'Mirror displays' option is now disabled, and each time I switch from
one option to the other, 4 instances of the display window are being
opened. Overall, not the way to go.

@André

It would be great if you could post an updated version of Sean's patch!

[Linux-traipu] [Bug 1308105]

[Liviu Andronic]

Hi!

Unfortunately this doesn't seem to help in my case. I've installed a
patched 4.11.3 (from my PPA here:
https://launchpad.net/~landronimirc/+archive/ubuntu/collection ,
includes fix_for_bug11107.patch), then logged out, logged in.

Then: 
- connect HDMI cable for external display
- in simple dialog select Display #2 (right-most choice)
- then select Display #1 (left-most choice)
- then unplug HDMI cable

More often than not this is sufficient to trigger the xfsettingsd crash.

  detected/ we've deteremined it's a X client that reacts to the RANDR
  events causing the mode to be set to NULL.

  Working through the list in an Xfce environment, the culprit is
  xfsettingsd.  If xfsettingsd is running, it causes the TV to come up
  in a NULL mode.  If it's killed, it remains in the mode it was
  previously running in.

  
  Until this is fixed, this behavior can be worked around with a simple shell 
script:
  ==
  #!/bin/sh
  #Fix TV state when HDMI link is lost.
  #By Mario Limonciello supe...@ubuntu.com

  OUTPUT=HDMI-0
  BAD_MODE=1280x720
  GOOD_MODE=1920x1080

  for MODE in $BAD_MODE $GOOD_MODE; do
   DISPLAY=:0 xrandr --output $OUTPUT --mode $MODE
   sleep 2
  done
