我无法超越图形登录屏幕，因为我apt-get upgrade在全新的 Ubuntu Dell 上运行的是 Ubuntu 14.04
.Xauthority、.ICEauthority和上的权限/tmp是正确的。重新安装 lightdm 没有帮助；我尝试了三次，但都失败了。切换到 gdm 导致黑屏，我花了半个小时才解决，然后我又回到了 lightdm。我安装了linux-generic，但没有帮助。这用尽了本网站上的所有建议。我有一张 nvidia 卡。知道我该怎么办吗？
以下是 的内容.xsession-errors：

我已经重新安装了 Ubuntu 两次以解决各种问题，但每次安装后都会发生登录循环，除了每次安装后的第一次登录。

答案1
@Zanna 和 @karel 的建议有效！我按照 Zanna 的链接安装了nvidia-375驱动程序。我不知道这是否与默认 Ubuntu 14.04 中的 nvidia-current 相同，但很可能是。它要求我重新启动并禁用安全启动。这些说明含糊不清/令人困惑，但我设法禁用了它。现在我可以登录了！谢谢！！我只希望下一次自动升级不会覆盖它。
