Fedora: System hangs after upgrade to FC18 (“started gdm”)

Question

I've been upgrading my eee laptop from Fedora 17 to 18. After a reboot the system shows up the boot message

[  OK  ] Started GNOME Display Manager.

and does not go on any further.

The system is alive, I can logon via ssh.

Any suggestions how to fix or debug this issue any further?

Thank you

Chris

Answer 1

I had the same problem after upgrading from F17 to F18. The last message of the system is:

[ OK ] Started Manage, Install and Generate Color Profiles.

Then the monitor blinks three times, probably trying to start GDM and stays still.

Answer 2

Well, in my case the start of the polkit service failed.

A reinstall of this service made my system work:

yum reinstall polkit

Try as root user (or use sudo):

yum distro-sync
