That may not be necessary. I experience "similar" behaviour, but the answer to that is *NOT* to restart X. Basically, X has told the monitor to not merely blank the screen, but to shut down altogether. When that happens to me, and I come back from a distraction elsewhere, I merely reach for the "Power" button on the monitor, and toggle it back on again. It's that simple. Try it.
The monitor if usually off when the described behaviour occurs. Even when it is on, power cycling it has no effect. It is not that simple. "xset -dpms" doesn't work, nor does "xset s off", nor does "setterm -blank 0 -powersave off -powerdown 0" If these commands are achieving ant result, it is being overridden elsewhere. Ctrl-Alt-F* followed by Ctrl-Alt-F1 *does* work - thanks to Mauro Sousa. It is a nicer kludge, and I appreciate it. However, I'd still love to figure out a real, permanent solution, if possible. The WM is OpenBox, which isn't doing any power management, but I will see if can get it to invoke a different power manager (XFCE looks promising, based on Lennart's experience) and try that. I will report back.
