Comment 6 for bug 1412730

Just wanted to add that I am experiencing a similar issue with the 2415 not waking after suspend. I don't seem to be having the some problems with screen resolution, monitor detection, or weirdness with xrandr commands. If I can get the monitor working, xrandr works correctly every time.

Essentially, if the screen goes into power save mode, I am forced to reboot in order to wake it up.

My other monitor is an HP ZR24w and I'm running a fully updated 14.04 on a desktop machine.

I'm not sure what further info or log files might be useful, but let me know and I'll try to provide whatever I can.
