CentOS 7.2 - no GUI login after upgrade

After installing and enabling the centos-release-cr repo on my CentOS 7.1
laptop; I ran yum clean all and yum update. Yum complained about gstreamer1
dependencies that is caused by epel repo; therefore, I excluded it from the
epel repo and run yum update one more time and it went through.

After the update was completed I rebooted the laptop and I will just get
the splash screen but will never get to the actual login screen; I have
experienced this in the past from CentOS 7.0 to 7.1 upgrade and at that
time it was caused by SELinux relabeling some of the configuration files;
e.g. /etc/passwd and /etc/shadow. This was discovered after I went into
single user mode and checked the journal.

I booted in the previous successful kernel that loaded and I experienced
the same behavior; therefore I went into single user mode from the latest
kernel that came with CentOS 7.2 and the previous kernel, checked the
journal and there were no errors that give me a hint of what is going
wrong. There are no SELinux relabeling but I left the laptop on for a few
hours because I was modifying a few directories to accommodate docker and
KVM storage from the default setup.

Any pointers on how to get the login screen?

Thanks in advance.

What about the gstreamer1 stuff, are all necessary
libraries (linkage) in place? Especially for the EPEL
stuff.

You *need* to upgrade the gstreamer libraries or you break gnome (which breaks
gdm). Uninstall whatever is clashing from epel, upgrade gstreamer, all will
be well.

There's a missing dependency there in the RPMs, but to be honest that's not at
all uncommon. I'd never recommend a partial update over a point release.

Thank Leon and John,

Removed the gstreamer that was installed from epel repo and I used the
packages that are from base and I am now able to login to the laptop.

Thanks again guys.
