Have either of you tested the suspend/resume behavior? Is that fixed too? No, I haven't had a chance to test the suspend/resume behavior, because that requires suspending at work, going home, and connecting to a dock which has a different monitor attached to it, and resuming (or vice versa of suspending at home and then resuming at work). So it's a bit trickier for me to test. It's also not a regression, and the workaround of rebooting is annoying, but I've lived with it for several releases now, but I'll try the two patches/changes that folks had suggested hopefully later this week. - Ted
