[Asus V-P5G45] No login page if I log out after using suspend

[Phill]

Sorry if this is reported against the wrong package. It works fine on my laptop so I'm operating on the belief this is a kernel problem as they're running the same software and I'm fairly sure that the settings are the same.

Steps to reproduce:
1) Start the computer.
2) Log in.
3) Wait for it to settle.
4) Put the computer into suspend.
5) Wake the computer with the power button.
6) Enter password to unlock.
7) Log out.

After logging out, instead of seeing the log-in page, the screen goes to sleep (monitor reports this) and stays that way. Most of the time I have to hard-power-off by holding the power button down.

What I've tried:
* I've tried pressing a few keys, enter, shift etc. but this has no effect.
* I've tried typing my password, logging-in blind, and this seems to cause some disk activity but the screen stays asleep.
* I've tried using CTRL+ALT+F6 (54321) to get to a terminal but no change.
* I've tried pressing the power button. On occasion this has caused what I assumed was a clean shut-down as the disc works and the system powers off shortly after. I'm not sure if this works in combination with terminal switching or something else.

What I've not tried, please let me know if any of these efforts would be worthwhile in diagnosing the problem:
* I've not tried clearing my profile or using a new user account as I'm logged out by this time anyway.
* I've not tried a clean re-install as I didn't want to wipe my machine without knowing that it would be useful for diagnosis.
* I've not tried booting from USB as I wasn't sure how to put the same package versions on my USB stick or if it even behaved the same at all.

Thanks

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 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.

Phill, could you please test the latest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc2-utopic/ and advise to the results?

Did this problem not occur in a release prior to Trusty?
