XServer 中的分段错误

我有一台华硕 ZenBook UX305，配备 i7 CPU 和集成英特尔 GPU。我的系统（Ubuntu 15.10）最近在运行一段时间后开始返回登录屏幕。这是由 XServer 中的段错误引起的。以下是系统日志片段

我还注意到，每次发生这种情况时，我都在使用 Chrome（但我不知道这是否相关，因为 Chrome 每次运行都有人知道问题可能是什么吗？我该如何调试它？我应该在 bugs.launchpad.net 上报告吗？

答案1

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，其内容如下：

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