Comment 0 for bug 1466940

When i try to wake up my monitor screens after they go into powersafe mode (they go dark after inactivity), the system crashes. I know the system works when powered down, because i can hear the system playing music. It's only after i try to wake up the system, the wholes system crashes (with blinking caps lock).

I suspect it has to do with the 2x 4k monitor screens attached to the Dell XPS 12, which the system can't handle as described in;

Even though, the system can handle just the 2x 4k screens with the laptop screen on off. I suspect the system tries to use all three screens temporarily while waking up.

It's not really an issue for me (i'll try to find out how to turn of the powersetting for the monitors), but i just thought lets report it so it's a known issue.
