求助：Tumbleweed版本图形界面循环登录

[baisy (xba)]

今天不知道怎么搞的，笔记本重启之后，图形界面就一直登录不上。输入密码后，黑屏1秒左右，然后又回到登录页面。一直卡在登录页面，循环登录。

我试了下，Ctrl+Alt+F6 进入纯文本界面之后， 命令行可以正常登录，登录后再 startx 是可以正常进入图形界面的。并且图形界面能正常使用。

我注意到，卡住循环登录的界面和平时登录的界面不太一样，
这是平时的登录界面：

这是卡住的登录界面：

还有一点，就是当我切换到 Ctrl+Alt+F1时，看到了一些提示，但不太明白是什么意思。

我回忆了一下，今天好像也没做什么特别的操作，实在不知道是什么原因导致的。

感觉像是显卡驱动出了什么问题

谢谢！

刚才发生了个很神奇的事情。我昨天装了个intel的fortran编译器，为了用它，在～/.bashrc 加了一句

“. /opt/intel/bin/ifortvars.sh”

刚才病急乱投医，试着把这一句注释掉，然后重启一下，发现好啦！不知道为什么，哈哈。

总结一下：
我系统设置的是开机免登录。正常开机是直接进入桌面，而不出现登陆界面的。

我刚试了一下，这个错误可以复现，只要在 ～/.bashrc 或者 ～/.profile 里面加上上面这一句，开机后就会卡在登陆界面，进不去。要装intel全家桶的小伙伴以后要注意了。

这样又出现了一个矛盾：要用ifort编译，每次都要运行 /opt/intel/bin/ifortvars.sh 。如果把 “. /opt/intel/bin/ifortvars.sh” 放在 ～/.profile 或～/.bashrc 里面，开机又会出问题。无解

那个sh文件里有啥呢？

大概是一些设置intel fortran编译环境的东西吧。。。没仔细读过

并且还发现, 在我的台式机leap 15.1 上, 并不存在这个问题, 可以随意将

. /opt/intel/bin/ifortvars.sh

加入 ~/.bashrc 里面. 没有任何问题.

请试试用 xorg 方式登录，wayland 可能会出现这种故障。
