Comment 103 for bug 745112

This bug, or one a lot like it, seems to have regressed on oneiric (3.0.0-11). If I boot up my x201 with the external monitor connected, it normally but not always works. When it comes back from the screensaver, normally the external screen will be blank but switching to vt1 and back does get the screen back (showing the unlock dialog.) If I connect the screen after the machine has booted, both the internal and external display are persistently black. In this case switching to vt1 does show a text login prompt, but switching back to vt7 just makes them both black again.
