Xorg crash

[Юрий Чудновский]

Random crash. Possibly same cause as in https://bugs.launchpad.net/xorg-server/+bug/1511484
Got crash while playing Xenonauts (Linux Steam version).

I also suffer from this exact bug, as several other users do and have reported in a number of other bugs such as:

bug #1509846
bug #1511615
bug #1511704
bug #1511512
bug #1511476
bug #1510998
bug #1511343
bug #1511145
bug #1509622
bug #1509355
bug #1506321
etc.

Common patterns are:
- Intel graphic cards
- Ubuntu 15.10
- Unity desktop environment
- Xorg crashes while opening a window or menu within applications such as thunderbird/libreoffice/etc.

It's just a matter of time before you will be asked to update your bios, the bug will be marked invalid, and Ubuntu 15.10 will be another successful milestone for Microsoft Windows. Cheers.

Meanwhile, you can reduce the occurrence of this bug by disabling window animations in Compiz. Use compizconfig-settings-manager for this tweak (sudo apt-get install compizconfig-settings-manager). You can also use desktop environments such as XFCE and LXDE which do not use compiz.

You partially right, aldebx. Compiz is essential for crash. But Unity is not. Under Metacity I found no crashes today.

Status changed to 'Confirmed' because the bug affects multiple users.

@fqc I didn't run into this issue for several days after upgrading to kernel 4.3 from http://kernel.ubuntu.com/~kernel-ppa/mainline/
Please join me in testing is this bug has been fixed upstream.

My current kernel:
Linux 4.3.0-040300rc7-generic #201510260712 SMP Mon Oct 26 11:14:07 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

[Юрий Чудновский (fqc)]

Disconfirm 4.3.0-040300-generic kernel at least for "(EE) TouchListenerGone: couldn't allocate events" crash. Same for windows animations - only turning off compositing/OpenGL support at all leading to no crash, any else I tried still crashing Xorg.
