After the crash I installed the suggested kernel and now got the following version installed: Linux hostname 4.4.0-040400rc8-generic #201601051225 SMP Tue Jan 5 17:27:39 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux Please note that I saw the following warning during the kernel installation: W: Possible missing firmware /lib/firmware/i915/skl_guc_ver4.bin for module i915 I don't know if this prevents us making sure that this error is fixed in the kernel I installed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1523444 Title: Xorg crahed with segfault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1523444/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
