[Touch-packages] [Bug 1521403] Re: Unity8 crashes with SIGSEGV in Screen::makeCurrent (./src/platforms/mirserver/screen.cpp:406)

2017-01-18 Thread Daniel van Vugt 
Yeah, sorry I was meaning to tell you but never caught you on IRC... I
noticed Xmir does modify the display config, but only to implement DPMS.
That's legacy code from the days when Xmir was full screen. Although
full screen mode is also the default mode. So I'm wondering if we need
to make the behaviour conditional rather than delete the feature. It
should be disabled in windowed and rootless modes...

It is actually valid for apps to be able to change the power mode of the
display. mirout in Mir 0.26.0 has such an option. But I agree it's bad
for apps to do it unexpectedly.

2017-01-18 Thread Gerry Boland 
Yeah I figured it out. Non rootless (rooted!) XMir wants to decide the
display power state (DPMS). Unity8/QtMir never had to deal with clients
doing that before.

Longer term Unity8 should filter such requests as it's quite rude for an
app to be able to turn off your display on you, but I've a branch up to
at least not crash.

I've more work to do on this though, as waking up the display isn't
working with that branch. To be continued

2017-01-11 Thread Gerry Boland 
I'm failing to reproduce this unfortunately. I'm also failing to create
a libertine container. It was failing due to bug 1653973, so I installed
silo 2341, but now it fails with:

Failed to download http://images.linuxcontainers.org//meta/1.0/index-user
LxcContainer.py:254: ERROR: create_libertine_container(): Failed to create 
container
libertine-container-manager:94: ERROR: create():Failed to create container

This is odd, as networking is fine, and I can wget that URL
successfully.


I've left my AMD laptop running with unity8 for hours yesterday, and no crash.

Can you paste more of that unity8.log please? From the output, it
indicates that the physical display state changed somehow, or at least
Mir thinks it did. Disabling screen blanking was a good idea, but are
you sure it worked? How did you try it?

Also, what GPU have you got?

Some more data points...

I disabled the screen blanking, but that made no difference.

But with the screen not blanked, I started an X app through Xmir and
left U8 idle and observed at almost exactly 10 minutes of idle time, U8
crashed.  This is what was in unity8.log at the time of the crash:

2017-01-09 Thread Christopher Townsend 
This is the easiest way to reproduce for me:

- Unity 8 desktop session, either X+O or Zesty
- Create a Libertine container and install an app in it such as Firefox.
- Start the X app.
- Wait ~30 minutes, ie, leave the system alone.

Xmir seems to exacerbate the issue, but I have observed the crash
without Xmir running.

Bug #1654581 was duped to this one, but I will say that the crash has
become much more prevalent, like nearly 100% reproducible after the last
