[Bug 45018] Re: Unlock screen is invisible with Nvidia twinview

[Marius Gedminas]

I too suffer from invisible unlock screen, but I have a Radeon card, not
Nvidia.  I do use dual-head layouts (MergedFB) also, but the unlock
screen appears invisible even in single-head mode. I can type in my
password blindly and unlock the session.

This seems to only happen when I use the 'blank screen' screensaver.
