Description of problem:
Screen goes blank after 30-60s of "inactivity" (like reading an email).
I've looked for many minutes under "Preferences", there's no hint anywhere
of a screensaver option.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Read an email, screen goes blak
This didn't happen until today.
In fact, it's not always -- I tried waiting for 60s, nothing happens. But quite often, the screen goes blank (monitor displaying "no signal") faster than 60s -- very, very annoying.
I've measured it exactly -- it's reproducible at 120s.
