The monitor won't wake up after going to sleep (initiated by locking, automatic or manual)

xorg (Ubuntu)

Bug Description

I am using the 3.16.3 kernel (edit: now 3.17 RC6!) and Mesa/drivers/Xorg from the Oibaf PPA - but this also happens when using drivers from the regular repositories.

Steps to reproduce:
1. Lock computer (Ctrl+Alt+L) or let it lock itself automatically
2. Wait a few seconds for the monitor to shut down (LED blue->yellow and displayed warning)
3. Try to wake it up

Expected behavior: the monitor is woken up and the Ubuntu lock screen is displayed

Actual behavior: the monitor stays off, black screen

Additional information:
 - Suspending and resuming works fine.
 - Switching to a TTY doesn't work either, but the keyboard is responding (can turn caps lock on/off).
 - I have to restart the computer to get it in a working state after this happens. (therefore SEVERE)
 - monitor: HP ZR2330w

WORKAROUND: Don't lock the computer, and disable automatic lock in Brightness & Lock settings.

WORKAROUND: Use proprietary AMD drivers (fglrx).

WORKAROUND: Use kernel 3.13.

Jan Corazza, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from .

If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 1372409

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful.

Thank you for your understanding.
