  Plasma crashes when the monitor is disconnected (when it sleeps, in

Status in qtbase-opensource-src package in Ubuntu:
  Fix Released

Bug description:
  I'm reporting this on behalf of a coworker who has a 4K monitor, which
  disconnects whenever it sleeps.  Older monitors didn't do that; but Qt
  5.5 tries to be honest about it: the QScreen is destroyed whenever its
  corresponding monitor is disconnected,
  QGuiApplication::primaryScreen() returns null, and so on.  KDE
  developers have been complaining.  So in Qt 5.6 we made it keep the
  last-remaining QScreen as a fake instance, whenever the last monitor
  is disconnected.  The main patch is here

  https://codereview.qt-project.org/#/c/138201/

  You might need to cherry-pick that
  (a094af001795c9651b299d700a992150d1aba33a in qtbase) for as long as
  you are shipping Qt 5.5, to get Kubuntu behaving decently.  It's
  relevant on Ubuntu 16.04.  Too bad that Ubuntu LTS is not shipping the
  LTS Qt 5.6 release, but I know we are behind on our release schedule.

  Some users have also reported that their laptop's screen disconnects
  when it sleeps.  And I have often experienced 5.5-based builds of
  Creator crashing or disappearing when I switch machines on my KVM.
  So, sorry that we didn't fix it sooner.  It was my mistake for
  believing that modeling disappearing screens "correctly" was a good
  idea: it turned out to be a platform inconsistency which developers
  were not ready for.

I'm publishing the current silo as it seems to improve things and no
regressions spotted. I'll ask you to test yet another build next week
with Paul's promising sounding patch if I get it backported:

2016-02-26 Thread Shawn Rutledge 
I installed the ppa.  I have two monitors.  Disconnecting and
reconnecting one is OK, but I have a script for disconnecting and
reconnecting both; in that case plasma still crashes.

#!/bin/sh   

  
restore=`unxrandr`  

  
outputs=`xrandr | grep -i "^\\w" | grep connected | cut -d' ' -f1`  

  
alloff="xrandr" 

  
for o in $outputs   

  
do  

  
alloff="$alloff --output $o --off"  

  
done

  
echo $alloff

  
echo $restore   

  
$alloff
sleep 2
$restore

[Touch-packages] [Bug 1548766] Re: Plasma crashes when the monitor is disconnected (when it sleeps, in some cases)

2016-02-25 Thread Ryan 
I tested the ppa in comment #5, and I note the following changes.

Environment is a docked laptop with 2 external displays.

When the laptop is removed from the dock (external displays
disconnected), I no longer receive a segfault for plasmashell, but the
panel does not automagicailly resize to the new resolution.

When the external displays are reconnected, plasmashell segfaults (same
as previous/xenial behavior). I think this issue is resolved in QT5.5,
but not specific to this bug/patch.

Atleast I don't have to restart plasma every time I dock/undock, but
behavior is still less than optimal. Progress though.

[Touch-packages] [Bug 1548766] Re: Plasma crashes when the monitor is disconnected (when it sleeps, in some cases)

2016-02-25 Thread Timo Jyrinki 
Hi! Could you test by upgrading to ppa:ci-train-ppa-service/landing-031
on xenial? (qtbase version 5.5.1+dfsg-14ubuntu2~xenial1~test10)

The patch in question was not trivial to backport due to multitude of
changes after 5.5 but before this patch in 5.6, but in the end I managed
to leave the rebasing modifications quite small, while taking in two
other patches and one line of code from a third patch.

It seems to continue to work fine in single monitor case with KDE but I
can't test the actual bug at the moment.

I've been suffering the same issue.  Plasma crashes every time my 4K
monitor sleeps or is turned off in Kubuntu 15.10. I had to pull in Qt

  5.5 tries to be honest about it: the QScreen is destroyed whenever its
  corresponding monitor is disconnected,
  QGuiApplication::primaryScreen() returns null, and so on.  KDE
  developers have been complaining.  So in Qt 5.6 we made it keep the
  last-remaining QScreen as a fake instance, whenever the last monitor
  is disconnected.  The main patch is here

  You might need to cherry-pick that
  (a094af001795c9651b299d700a992150d1aba33a in qtbase) for as long as
  you are shipping Qt 5.5, to get Kubuntu behaving decently.  It's
  relevant on Ubuntu 16.04.  Too bad that Ubuntu LTS is not shipping the
  LTS Qt 5.6 release, but I know we are behind on our release schedule.

  Some users have also reported that their laptop's screen disconnects
  when it sleeps.  And I have often experienced 5.5-based builds of
  Creator crashing or disappearing when I switch machines on my KVM.
  So, sorry that we didn't fix it sooner.  It was my mistake for
  believing that modeling disappearing screens "correctly" was a good
  idea: it turned out to be a platform inconsistency which developers
  were not ready for.
