[Desktop-packages] [Bug 1626935] Re: [yakkety] desktop is black and/or flickering after plugging in a second monitor

[Alberts Muktupāvels]

Was this tested with HiDPI? On fully updated VM (zesty) with scaling-
factor set to 2 initially window size is correct, but after resizing VM,
nautilus desktop window is 1/4 from size it should have.

I think that I have same problem also on my main pc (also zesty) -
desktop window is only 1/4 after resolution changes. Restarting nautilus
"fixes" problem until next resolution changes.

[Desktop-packages] [Bug 1626935] Re: [yakkety] desktop is black and/or flickering after plugging in a second monitor

[Rocko]

@Christopher:

1) It's a physical machine (my laptop).

2) I'm using Ubuntu 16.10.

3) Graphics-wise, it's a standard installation except for the 4.9-rc3
kernel from mainline and a PPA for nvidia graphics drivers (but I wasn't
using the nvidia card at the time this happened, it was all on the Intel
GPU).

I only mentioned it because it looked exactly like what this bug would
have looked like if the laptop screen had been resized to a larger
vertical resolution, say from 1920x900 to 1920x1080, and because just
like this bug, killing and restarting nautilus fixed it (and I *was*
already running the updated nautilus 1:3.20.3-1ubuntu3.1).

I haven't seen it happen again, though, so it's not worth following up
on at this stage since I can't readily reproduce it.

[Sinclair Yeh]

This also fixes a defect we are seeing in a VMWare guest with Ubuntu
16.10.  The issue was wallpaper does not get resized when changing to a

Rocko (rockorequin), you may be affected by another bug outside of the
scope of this report. Hence:

1) Are you referring to a physical, or virtual machine?
2) Are you using Ubuntu 16.10 or some other version?
3) Do you have any PPA/3rd party software installed or is it the default 
configuration?

[Desktop-packages] [Bug 1626935] Re: [yakkety] desktop is black and/or flickering after plugging in a second monitor

[Rocko]

I also saw artefacts this morning all along the bottom 10% of the
desktop background on the laptop monitor (the launcher was rendered
without issues). I'm not sure what triggered it, but I had resumed the
laptop and plugged in a new monitor earlier in the morning. Killing
nautilus and restarting it fixed the problem.

Although I saw some concerning artifacts when running zesty in a

been caused by this fix(?). Needs investigating.

  configuration. Instead of your wallpaper you see black.

  [ Fix ]

  Inside nautilus, the wallpaper widget connects to GTK's "monitors-
  changed" signal when it is constructed. It does this only once the
  widget is realized - a "realized" signal handler connects to
  "monitors-changed". In Yakkety, the "realized" signal handler is
  connected after the widget is already realized, meaning that the
  signal handler isn't called and we don't connect to the "monitors-
  changed" signal.

  The proposed fix remedies this by checking if we are realized and
  explicitly calling the signal handler if so.

  [ QA ]

  Have multiple monitors. Have only one of them connected. Log in. Plug
  in one monitor. If it's autoactivated, check you see your background
  on both monitors. If not, activate it ("Displays") and do the same.

  [ Regression potential ]

  I'm not sure why or where the order changed to make the widget be
  realized earlier, if it matters or if this was always buggy and we got
  lucky. I would guess a refactoring in Nautilus itself, and so the
  proposed fix is safe, but watch out for other weirdness.

Cool. That would also be the nautilus-in-Xmir wallpaper bug I
encountered recently when you resize the desktop window. I thought it
was Xmir's fault but it's probably this one.

  Have multiple monitors. Have only one of them connected. Log in. Plug

  I'm not sure why or where the order changed to make the widget be

[Rocko]

It looks like this bug is reproducible in VirtualBox by resizing the
guest window. After the nautilus update in yakkety-proposed, the bug is
fixed for that use case.

  Inside nautilus, the wallpaper widget connects to GTK's "monitors-
  changed" signal when it is constructed. It does this only once the
  widget is realized - a "realized" signal handler connects to
  "monitors-changed". In Yakkety, the "realized" signal handler is
  connected after the widget is already realized, meaning that the
  signal handler isn't called and we don't connect to the "monitors-
  changed" signal.

  The proposed fix remedies this by checking if we are realized and
  explicitly calling the signal handler if so.

  [ QA ]

  Have multiple monitors. Have only one of them connected. Log in. Plug
  in one monitor. If it's autoactivated, check you see your background
  on both monitors. If not, activate it ("Displays") and do the same.

  [ Regression potential ]

  I'm not sure why or where the order changed to make the widget be
  realized earlier, if it matters or if this was always buggy and we got
  lucky. I would guess a refactoring in Nautilus itself, and so the
  proposed fix is safe, but watch out for other weirdness.

[Brian Murray]

Hello Yung, or anyone else affected,

Accepted nautilus into yakkety-proposed. The package will build now and
be available at
https://launchpad.net/ubuntu/+source/nautilus/1:3.20.3-1ubuntu3.1 in a
few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

[Desktop-packages] [Bug 1626935] Re: [yakkety] desktop is black and/or flickering after plugging in a second monitor

[Iain Lane]

I'm fixing this by explicitly calling the signal handler once if the
widget is already realized when we connect the signal.

  [ Description ]

  Nautilus's wallpaper drawing doesn't respond to changes in monitor
  configuration. Instead of your wallpaper you see black.

  [ Fix ]

  Inside nautilus, the wallpaper widget connects to GTK's "monitors-
  changed" signal when it is constructed. It does this only once the
  widget is realized - a "realized" signal handler connects to
  "monitors-changed". In Yakkety, the "realized" signal handler is
  connected after the widget is already realized, meaning that the
  signal handler isn't called and we don't connect to the "monitors-
  changed" signal.

  The proposed fix remedies this by checking if we are realized and
  explicitly calling the signal handler if so.

  [ QA ]

  Have multiple monitors. Have only one of them connected. Log in. Plug
  in one monitor. If it's autoactivated, check you see your background
  on both monitors. If not, activate it ("Displays") and do the same.

  [ Regression potential ]

  I'm not sure why or where the order changed to make the widget be
  realized earlier, if it matters or if this was always buggy and we got
  lucky. I would guess a refactoring in Nautilus itself, and so the
  proposed fix is safe, but watch out for other weirdness.

[Desktop-packages] [Bug 1626935] Re: [yakkety] desktop is black and/or flickering after plugging in a second monitor

[Iain Lane]

GTK or nautilus itself somehow changed the order that things are
realized in, which broke an assumption in nautilus that this would
happen after the widget was constructed.

[Daniel van Vugt]

Whatever the logic in nautilus listening for xrandr display layout
changes is, is what seems to be broken. It should be reconfiguring
itself when xrandr reports the displays have changed.

[Desktop-packages] [Bug 1626935] Re: [yakkety] desktop is black and/or flickering after plugging in a second monitor

[Treviño]

I've the impression this is due to nautilus not being properly resized
when display size changes (in a VM) or a new one is added...

nautilus -q

and starting the filemanager again should fix this.

[Daniel van Vugt]

I thought it was plausible the underlying cause was the modesetting
driver but up in comment #4 Timo said that it happens without
modesetting and in intel too. So which is true?

[Desktop-packages] [Bug 1626935] Re: [yakkety] desktop is black and/or flickering after plugging in a second monitor

[Rocko]

Is this a modesetting driver issue? I believe I've seen this happen when
hotplugging an external monitor. It only happens for me with the modeset
driver, though, not the intel driver. The modesetting driver is
excellent for some things (eg it doesn't tear on the external monitor
like the intel driver does), but it does struggle a bit when changing
resolutions and screen layouts (eg every time I log in, it completely
unnecessarily changes my laptop screen resolution from 1920x1080 to
640x480 and then back again to 1920x1080).
