The fedora20 in vmplayer cannot enter the graphic interface.

A new virtual machine named fedora20 is installed. After installing and upgrading some items, the black screen is displayed after the logo screen of fedora is started. No error is prompted. Fortunately, the shell can still go in and view the/var/log/anaconda/syslog log. The error is as follows:

This indicates that some operations are rejected. if the first one is selected, avc: denied indicates that the operation is rejected, {Read write} indicates that this operation requiresRead-read andWrite-write permission.Pid = 1, 26214Indicates that a process with process no. 1876 is trying to execute operations ...... And so on. These are SELINUX security checks. Before executing a system call, the kernel will ask whether the SELinux process has been authorized to execute the operation.

The solution is also very simple, that is, to authorize the corresponding process or disable SELINUX. Here, I select the latter, modify the file/etc/selinux/config

SELINUX=enforcing

Change 

SELINUX=disabled

Restart the instance.
