Monitors go into stand-by when only using one monitor

[Sir Nikon]

Binary package hint: mythtv

I do apologize for the confusing summary.

I recently connected another monitor to my computer (which was a whole slew of issues that are almost resolved). I've noticed that with the monitor standby power setting set (which currently is at 5 minutes), the monitors go into standby regardless of whether or not the computer is in use. So, even if I'm using the computer, the monitors will still fade away and shut off, but quickly turned back on when I press a key or move the mouse (meaning, standby works as properly, except it always goes to standby, whether idle or not).

Before I connected the new monitor, standby worked properly and would not go into standby unless the computer was idle or not being used.

I run MythTV on a separate monitor. I use the other monitor for all of my other computer activities (Internet, documents, graphics, etc.). It seems that if MythTV is running but nothing is being done within the program, the computer will send both of the monitors in to standby mode. If I move my mouse or type a key on the MythTV screen, it seems to prevent the issue (meaning standby works).

I hope this sums up the issue. It seems to be difficult to really say what the issue is.

I made an error when posting this.

It happens regardless of whether or not MythTV is running.

After a little bit of further reading, it is now my understanding that when you have dual monitors, it causes Gnome to run two instances (one for each monitor). It would seem that since it is running two instances, the instance not being used would consider itself idle and send the system's monitors into standby.

Have you seen this

Specifically, the section sub titled "Screen goes blank but returns when mouse is moved or keyboard is used"

This sounds connected to a bug with Gnome which I reported a while back.

Your main screen is prob the one with mythtv running on, and your prob working on the 2nd screen. The problem is the xscreensaver and standby stuff seems to only work with the first screen. Try swapping them around, or turning of standby and get in the havit of turning them off yourself for a quick hack of a fix.
