Display Settings Command Line Equivalent

[Ed Greshko]

The situation is this....  I have a dual monitor setup.  One on HDMI the other on DP. 
Once in a while the monitor on DP won't restore have being switched off by the
"Energy
Savings" settings.  There are several ways I've found to get it back.

1.  Disconnect/reconnect the cable.

2.  Logout/Login

3.  Disable/Enable the monitor in "System Settings".  But this turns out to be
multi-step
process since at one point the monitors will combine in the display and I need to move
them apart otherwise I just get a duplicate monitors.  Not a big deal....just a pain.

So, can anyone take a stab at what a command line entry would be for option #3 above?

I suppose I knew that was going to be the answer.  And I suppose it is a good exercise to
have figured out the needed commands.

Now, all I need to figure out is why issuing these commands....

xrandr --output DP-1 --off
xrandr --output DP-1 --right-of HDMI-0 --auto

causes any of my running apps to lose the ability to play sound until they are restarted.
