XServer中的分段错误

我有华硕ZenBook UX305与i7 CPU和集成的英特尔GPU。 我的系统(Ubuntu 15.10)最近开始在一段时间后恢复登录屏幕。 它是由XServer中的段错误引起的。 这是syslog片段

我也注意到每次发生这种情况时,我都在使用Chrome(我不知道这是否相关,因为Chrome运行的每一个都有人知道问题可能是什么?我怎么能调试它?这是我应该做的事情吗?关于bugs.launchpad.net的报道?

我设法通过使用此处描述的解决方法解决了我的问题:

https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1510970

禁用SNA。

我创建了/usr/share/X11/xorg.conf.d/20-intel.conf文件,其中包含以下内容:

 Section "Device" Identifier "Card0" Driver "Intel" Option "AccelMethod" "uxa" EndSection
