Just wanted to bring attention to this issue so it gets fixed.
Description of problem:
Black/blank screen instead of login window in gnome with SELinux enabled on RHEL 7.1. Catalyst 14.12 Works with SELinux enabled. Have not tested 15.5.
Steps to reproduce:
1. Install Catalyst 15.7
2. Reboot and get a blank screen instead of the login window in gnome.
3. Disable SELinux and reboot
4. Login screen works
No login screen
Login screen should work with catalyst and selinux enabled.
Also added to unofficial bugzilla Bug 1188 – RHEL 7.1 and Catalyst 15.7 does not work with SELinux enabled
