Comment 1 Lars S. Jensen 2013-11-10 11:27:14 UTC

It is also gdm that has problems.
startx is working.

Reproduced: reboot and not login screen.

Workaround is to run startx from a VT login if .xinit is correct configured.

fix: yum downgrade selinux-policy selinux-policy-mls selinux-policy-targeted
