[Bug 1511615] Re: 8086:0a26 xorg crashes on Ubuntu 15.10 with Intel graphics


aldebx, thank you for reporting this and helping make Ubuntu better.
However, your crash report is missing.

Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer. First, execute at a terminal:
cd /var/crash && sudo rm * ; sudo apt-get update && sudo apt-get -y dist-upgrade && sudo service apport start force_start=1

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart. Now reproduce the crash, then open a terminal, navigate to your /var/crash directory and file your report with:
sudo ubuntu-bug /var/crash/_my_crash_report.crash

where _my_crash_report.crash is the crash you would like to report. By
default, this sends the crash to the Ubuntu Error Tracker
infrastructure, which is different than Launchpad. For more on this,
please see https://wiki.ubuntu.com/ErrorTracker .

However, if after doing this you would still like to have a crash report posted to Launchpad, for example to ease triage and add others to your report, one would need to open the following file via a terminal:
sudo nano /etc/apport/crashdb.conf

and comment out the line:
'problem_types': ['Bug', 'Package'],

by changing it to:
# 'problem_types': ['Bug', 'Package'],

Save, close, and file the crash report via:
sudo ubuntu-bug /var/crash/_my_crash_report.crash

If you do open this report, please feel free to subscribe me to it.

However, I'm closing this report since the process outlined above will
deal with this issue more efficiently. Also, please do not attach your
crash report manually to this report and reopen it. Thank you for your

  8086:0a26 xorg crashes on Ubuntu 15.10 with Intel graphics

Status in xorg package in Ubuntu:

Bug description:
  Symptom: xorg crashes on windows creation

  How to reproduce: No 100% reproducibility, however intensively using
  2D/3D acceleration triggers the bug (e.g. by opening several new
  windows and/or menus in a Unity desktop environment)

  Affected hardware: Intel HD Graphics 4400/5000 etc
  Affected software:
  - kernel Linux 4.2.0-16-generic #19-Ubuntu SMP x86_64
  - also affected is kernel Linux 4.2.5-040205-generic x86_64
  - Ubuntu 15.10 with Unity (because of compiz 2D/3D acceleration)
  - any other software using direct rendering (e.g. VLC)

  - Disable window animations in Compiz reduces the frequency of the crashes.
  Use compizconfig-settings-manager for this tweak (sudo apt-get install compizconfig-settings-manager)
  - Use XFCE or LXDE also reduces the frequency of crashes given that these desktop environments are 2D only
