I am using Gnome remix with Ubuntu 12.10 in my dual screen setup 2560 x 1440 + 1600 x 1200. The problem that I am facing is when my computer resumes from stand by, I cant see the login window or type anywhere. Another inconsistency that I have notices is when my computer boots my screen is shifted half left so I have to drag my mouse on the left to reveal the rest of it. Any ideas about how to restore proper functionality? I am using GDM for session management.
