Nouveau Xorg driver

Bug Description

Ubuntu 14.04 installed on a laptop (Sony Vaio PCG-51111V in my case).
When the lid is closed it goes to suspend mode.
When I turn it on after suspend mode:
1. Unity greeter lock screen appears but I cannot enter my password because it doesn't react on any key presses on the keyboard.
2. After about 1 minute Unity greeter lock screen disappears for a second and appears again with a classical drum sound (system-ready.ogg).
3. Now keyboard works fine and I can enter my password.
4. But after entering password I see only clean screen with my wallpaper and "ubuntu 14.04 LTS" label. No pannels, no windows, no applications. And it doesn't react on keyboard anymore.
5. Power off/on is only way to make Ubuntu works again after suspend.

Version: Ubuntu 14.04-beta2 (i386) clean install.

affects: gnome-screensaver (Ubuntu) → unity-greeter (Ubuntu)

This bug also affects xubuntu.
So it could be on the kernel layer.

This is really annoying. Wake from suspend bugs were supposed to be fixed a long time ago... I think i'll revert to 13.10 till it gets fixed.

The problem seems to be the stupid default neveau video driver. I installed NVidia binary X.Org driver ('current' driver) from the software center and it now resumes ok from suspend.

You are right.
My laptop is using nVidia GeForce 310M (GT218M) graphics chip.
So I've opened Software & Updates -- Additional Drivers:
And have switched selection from "Using X.Org X server - Nouveau display driver from xserver-xorg-video-nouveau (open source)" to "Using NVIDIA binary driver - version 331.38 from nvidia-331 (proprietary, tested)".

After applying changes and rebooting this bug has disappeared.
Resuming from suspend mode works fine now.

It's a kind of workaround for me.
But I'm sure this 'broken suspend' bug should be fixed in the open source Nouveau display driver.

affects: unity-greeter (Ubuntu) → nouveau

Problem still exists in 14.04 LTS stable release!
I made 2 new fresh installs on 2 different laptops, and they both have this problem.
How could that ever be released as is?

Shouldn't someone be assigned to this bug?

The best part of it is that when I try to enable the proprietary driver, my choice is changed back to nouveau...
so sad :(

Some error in hashes of the Greek repo was causing a (silent) error...
Changed to Main server repos and the change to proprietary driver worked.
Resume from suspend fixed :)
