在更新了一堆软件包并重新启动后,我尝试登录我的 Ubuntu 桌面。我知道我已成功验证身份,但似乎发生了这样的情况:在我输入用户名和密码后,屏幕暂时变为全黑,然后再次加载登录页面。
我不知道在哪里可以找到与此相关的错误。任何建议都将不胜感激。
更新:
如果我failsafe GNOME
从会话列表中选择,我可以正常登录。有什么想法吗?

以下是 的输出~/.xsession-errors

您应该删除该行中的function
关键字或括号()
。这在不同版本中的实现有点不一致bash
--- 可能是您的更新引入了一些不兼容的版本bash
。
为我
nameofsomefunction() {
...
}
大部分时间都有效。
