The flashing-light daemon reported problems with coreutils. So I rebooted. System would not go to runlevel 5, but 3 was good. I discovered that abrtd was looping, using about 50% of the CPU. Pushing that aside and rebooting, serious complaints from selinux. Disabled that. On reboot discovered that gdm was failing; probably the root of the problem. No errors in X.0.log.

Start with rpm --verify --all  > log

and the log will tell you if any binaries and stuff like that are
corrupted.
