[Bug 1604657] Re: [Regression] Unity shows blank desktop with software renderer

2016-08-10 Thread Luke Granlund 
I have tested the proposed packages with success on VM snapshots from
both before and after the issue originally occurred.

I believe I've also tracked down the source of the problem to failing to
upgrade Compiz from "1:0.9.12.2+16.04.20160526-0ubuntu1" to
"1:0.9.12.2+16.04.20160714-0ubuntu1" when Unity was upgraded to
"7.4.0+16.04.20160715-0ubuntu1" (both address low graphics settings)
even though they were published simultaneously.  This is most likely due
to phased updates in Software Updater and the fact that the Unity update
doesn't appear to list the Compiz one as a dependency.  In fact,
http://people.canonical.com/~ubuntu-archive/phased-updates.html reports
that this Compiz update is currently being withheld by Software Updater
due to crashes, while the Unity update is fully rolled out.  This
possibly explains why I saw the issue on an existing VM but not on a
fresh one.

Proposed packages installed:
libunity-core-6.0-9/xenial-proposed 7.4.0+16.04.20160801.2-0ubuntu1
unity/xenial-proposed 7.4.0+16.04.20160801.2-0ubuntu1
unity-schemas/xenial-proposed 7.4.0+16.04.20160801.2-0ubuntu1
unity-services/xenial-proposed 7.4.0+16.04.20160801.2-0ubuntu1

Here are the sequences of updates I applied in testing.

1. Non-working VM -> Upgrade all packages in xenial-updates with apt-get (still 
non-working) -> The proposed updates (Working)
Comment: The problem originally appeared after a Unity update in Software 
updater where unity, but not compiz, was upgraded.  Desktop appeared after 
upgrading to proposed, but I had to re-enable several Unity plugins to avoid 
annoyances.  For example, the "Grid", "Place Windows", and "Snapping Windows" 
plug-ins, which according to CCSM were all enabled before the proposed update, 
were disabled after it.  There may or may not have been other changes, these 
were just the ones I noticed, and perhaps this behavior is expected.

2. VM prior to broken update -> Upgrade all packages in xenial-updates with 
apt-get (working) -> Upgrade to proposed updates (Still working)
Comments: Here unity and compiz are simultaneously upgraded to their mid-July 
versions and the problem I experienced never occurs in the first place.  The 
proposed update doesn't appear to break anything.

3. VM prior to broken update -> Upgrade unity and compiz (and no other 
packages) to most recent in xenial-updates (working)
Comments: Basically as 2, but strongly suggests that May compiz package is 
causing the issue with mid-July unity.

4. Non-working VM -> Upgrade just compiz to most recent package in 
xenial-updates -> Create new user (works)
Comments: Unity seems to work with a new user, but I wasn't able to repair the 
existing user's account without installing the proposed packages.

Taken together I think that using Unity 7.4.0+16.04.20160715-0ubuntu1
with Compiz 1:0.9.12.2+16.04.20160526-0ubuntu1 is almost certainly the
cause of the issue.

No matter the original cause, the proposed
7.4.0+16.04.20160801.2-0ubuntu1 updates restored functionality (with the
minor caveats discussed in point 1) to the non-working VM, and didn't
break a working one.

[Bug 1604657] Re: [Regression] Unity shows blank desktop with software renderer

2016-07-27 Thread Luke Granlund 
Having a chance to look at things more closely, Unity definitely appears
to be running.  (By this I mean compiz started with the Unity plugin,
and unity-panel-service is running.)  Running unity from the command-
line stops and restarts everything, but the desktop remains blank.

However, running unity -v (according to the source for unity.cmake this
calls compiz with --debug) *does* restore things.  I've also gotten a
desktop by running compiz --replace.  Issues persist upon rebooting,
however.  As previously mentioned, this includes steps like deleting
.cache and .config, resetting things in dconf, and other standard
workarounds for blank desktop issues.  I also tried purging and
reinstalling essentially the entire graphical stack, without success.
That suggests the issues might be with the default settings, yet they
don't show up on a fresh 16.04 installation on the same platform.

I'm stumped and migrating to fresh VMs.  I'll keep a copy of the
troublesome VM around for a few months in case the issue is confirmed or
someone has a bright idea.

[Bug 1604657] Re: [Regression] Unity shows blank desktop with software renderer

2016-07-20 Thread Luke Granlund 
If Unity is running it's being very shy.  I have the same problem on a
different machine using a VM cloned from this one several weeks ago.  A
VM with a fresh install of 16.04 LTS works fine with the new packages
for me, so perhaps this is a unique configuration issue.  However, other
than experimenting with launcher placement and turning low graphics
on/off I haven't tweaked Unity settings to my recollection.  I've
noticed that CCSM when run from console (DISPLAY=:0 ccsm &) appears to
hang at "Loading icons...", which may point in the right direction.

I have Hyper-V checkpoints immediately before and after installing the
packages that break things for me, so I should be able to investigate
any before/after question that might help.

To answer your specific questions, there are no dumps in /var/crash.
I've attached before (working) and after (non-working) unity7 logs.
I've generated them by restarting the VM from the aforementioned states
and logging on, so the times in the logs might look inconsistent.
