I have ASUS K73SV notebook with dual graphics intel/nvidia. I'm using default intel driver, no proprietary drivers installed, and this bug also affects me.
1) Xubuntu installed from fresh daily build wakes up to login screen, after logging in screen turns blank, but hardware is alive - I can Ctrl- Alt-F1 to console and restart lightdm, after which I can login to desktop 2) Ubuntu installed from fresh daily build wakes up to login screen, after logging in all previously opened applications are closed, as if lightdm was restarted silently In both cases all previously run applications are closed, so suspend is unusable.

OS: Ubuntu 14.04 (updated today). After wakeup the notebook from the sleep mode, the screen goes blank while the OS and the hardware is awake. (I can also press Ctrl+F1 and Ctrl+Alt+Del to reboot the system). This problem is not happening with the AMD property drivers (but they have another bug, i can't set up the brighness of the monitor). The problem in my opinion is related to this package: xserver-xorg- video-ati. Changing "quiet splash" with "nomodeset" into /etc/default/grub makes the wakeup working, but the pc is really slow (can't be used), also after the normal start up. Best regards and have a good work.
