I have a problem with the Standby function: My Computer does not enter the Standby mode with Ubuntu 14.04LTS. If I remeber me right, it works with Ubuntu 13.10 but this Version was not long installed on this PC.
Now when i press Standby in the menu or on my Keyboard, the display turns black for a few seconds, then some messages appear for a very short moment on the screen. After that, the the log-in screen appear. Two times I was able to enter Standby but the other times it fails.
Tecnical Data about my PC:
- Ubuntu 14.04 with all Updates
- main storage: 3,8GiB
- processor: Intel® Core™ i3-2330M CPU @ 2.20GHz × 4
- graphic: Intel® Sandybridge Mobile
graphic board: NVIDA GEFORCE GT 555M CUDA 1GB
x64Bit Medion P6812 Laptop
Here is the message output:

Usally I got only a half or one third of the screen filled with messages like that. This time, when I filmed it, it was much more.
here is the log from /var/log/pm-suspend.log:
