I'm seeing what looks like the same problem on a fully updated 12.04 Lenovo T410 system with nvidia graphics. Note however, that the I see this screen corruption:
- briefly on every boot after the Ubuntu plymouth splash has disappeared, but just before the lightdm greeter appears. - on every boot after having logged in via the lightdm greeter but before Unity has started. Once I've entered my gpg+ssh credentials, the screen is refreshed and all returns to normal.
