It's recently gotten worse for me, because now it sometimes turns the second
monitor off when resuming from screen energy saving. Both monitors are always
enabled when resuming from suspend though (though that could be because I've
just turned the monitors on, as I turn them off when suspending).
It looks like it tries to turn it on though, in the journal I get output like:

I also get the same thing if I try to reenable the screen after disabling it.
In order to reenable the second screen, I first have to back out of the screen
settings, wait until the screen shows "no signal", and then reenter the screen
settings. I didn't leave and reenter the settings, or I reentered the settings
before the screen started showing "no signal", I get and error like above.
