omriasta, 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 http://cdimage.ubuntu.com

Issue is definitely related to DPMS. Disabling DPMS altogether prevents the
screen from turning off completely in turn preventing it from failing to turn
back on. Screen still blanks when I lock the screen but backlight remains on
and the screen doesn't go to "power saving" mode.
I have updated
Here is dmesg in 13.10:
