11.1 64bit after installation services don't start


I’ve tried this several times, and after I make a fresh install of 11.1, and reboot the system, some major services don’t work (network, nautilus, pendrive & cdrom mounting for example). Rebooting doesn’t help.

On a 32bit OS this doesn’t happen (it also worked on 11.1 64bit RC1).

I just crushed, because I don’t know, what to do, and I have to get this running within a day or two (need a 64 bit OS for my project).
