After fresh install of oneiric 11.10 nothing displayed during boot process, but I still can switch to tty's. I made apt-get update/upgrade from tty and tried to reboot. Nothing changed. 'service lightdm restart' and 'startx' also doesn't help.

**UPD(24.10.2011):** Just reported bug with apport-bug to [launchpad](https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/880898). You can see there logs and others collected reports.
