Earlier to day I rebooted, and after doing so I went about my normal business, but less than five minutes in my monitor showed all black and then the [No Signal] message before sleeping. This seems to repeat every time I try to use mint. I updated something in my previous session, so I suspect that, but don't know what that is. I'm writing this from my windows install with no issues on the same box, if that helps to rule out any possibilities.
I'm on linux mint 15 with Cinnamon.
Please help me!
