Xorg does not display login screen

[Luigi Rosa]

Binary package hint: xorg

With the latest versiuon of Maverick the boot process displays "UBUNTU 10.10" then the screen goes blank and there is no disk activity.

This happened three days ago, before that everything was ok.

If I remove nVidia drivers, the logon screen appears

Solved following the indications of http://www.ubuntugeek.com/howto-install-nvidia-drivers-manually-on-ubuntu-10-04-lucid-lynx.html and installing driver version 256.53

[Danilo Taveira (danilotaveira)]

Exactly the same thing happens with me. When uninstalling Ubuntu driver and installing NVIDIA'a 256.53 everything works fine.
