I have a fresh installation of Ubuntu 13.10 with the latest updates on my PC. I am having a issue where the monitor seems to randomly disconnect. I cannot pinpoint what is causing this issue. It can happen out of the blue, when I open thunderbird, or when I open an email in my browser, but nothing is consistent. I cannot reproduce any of these issues. It will work fine all day and nothing I don't do anything different when the issue arises.
I have installed caffeine and disabled the screensaver, disabled dpms, disabled power save settings/screen dim, and toyed with other xset commands that other's have had luck with when they had similar issues on previous versions of ubuntu.
I have not installed any additional software or drivers other than common apps through the software center. The problem occurred before any installations.
I have a dual monitor setup and both monitors lose input at the same time. The TV monitor goes to a blue screen and says "Invalid input" or "Out of range" if I recall correctly, and the other monitor switches quickly between digital and analog before eventually resting at an all black screen. Replugging the monitor doesn't do anything and the only way to get the screen back that I found is to pull the power plug and reboot, then it comes right back up.
I'm tech savvy but a linux amateur. I suppose my next step from here would be to check logs, but I don't know where to begin.
