Ubuntu 登录屏幕重新加载

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？

更新2： 以下是 的输出~/.xsession-errors：

/etc/gdm/Xsession: Beginning session setup...
/etc/profile.d/p4c.sh: 8: Syntax error: "(" unexpected

p4c.sh这是我从以前的 Ubuntu 系统复制的脚本 - 它在以前运行良好。以下是 p4c.sh 的内容：

#!/bin/bash

# p4c() function setup params
p4_HOST=`hostname | awk -F . '{print $1}'`

# function for setting the P4CLIENT variable based on the first non-option
# argument provided
function p4client() {

    VERBOSE_MODE=''
    DESC_MODE=''
    SHORT_MODE=''
    while getopts ":hdsv" option
    do
        case $option in
            h) echo "p4c provides information about perforce clients."
               echo "Recognized arguments:"
               echo "    -h     help (this message)"
               echo "    -d     descriptions (prints client descriptions - useful, but slightly slower)"
               echo "    -v     verbose (print unreasonable amounts of debugging info"
               echo
               # About to exit - reset OPTIND or we'll be in trouble later.

               return

            d) DESC_MODE='descriptions';;

            *) echo "Unknown option '$OPTARG'!  Specify -h for help..."

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。
