14.04.3 登录屏幕循环 显卡故障

我在 ASUS Netbook X201E 上运行着 14.04.3。今天,我无法登录我的账户。lightdm启动异常。不显示顶部栏。尝试使用正确的密码登录后(已测试,如果密码错误,回复有效),出现像素错误,登录屏幕再次出现。访客登录也不起作用。网络、ssh 访问等都正常。
我清除并重新安装lightdm,然后安装并启动gdm。问题仍然存在。访客登录曾经起作用,但显示了低图形模式警告窗口,但无法读取。只在鼠标悬停时出现一些橙色勾选框。在过去几天登录 unity 后,这个问题也出现了几次。

包含错误的摘录lightdm.0.crash,对我来说似乎相关:

(gtk-update-icon-cache-3.0:12099): GdkPixbuf-WARNING **: Cannot open     pixbuf loader module file '/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache': Datei oder Verzeichnis nicht gefunden

 This likely means that your installation is broken.
 Try running the command
   gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-    2.0/2.10.0/loaders.cache
 to make things work again for the time being.

我需要更新我的视频驱动程序吗?已添加ppa:ubuntu-x-swat/x-updates

非常感谢您的帮助!

这个答案对我有用 chown username:username .Xauthoritysudo chmod a+wt /tmp

Unity 问题似乎也得到了解决。
