Blank screeen after resuming from suspension

[Marco Ferretti]

The screen is left blank after resuming from suspension (close lid, open lid).
The computer wakes up but the screen is left blank. I can login to a different console and restart lightdm but that's not an acceptable work around.
Manually invoking pm-suspend works.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Just tested with upstream kernel :
uname -rv
3.16.0-031600rc6-generic #201407210035 SMP Mon Jul 21 04:56:43 UTC 2014

I have exactly the same behavior.
updated tag as requested
