Hi Juraj, I am on 14.04, though I have an iBook on 12.04... My machine with NVidia graphics had perfect suspend using the default drivers in 12.04, but for 14.04 I need proprietary drivers to suspend :(
Suspend is pretty much dependent on your graphics card, from what I know. Hmmm, Jorn was talking the other day about certain aspects of X that have changed in 14.04, I do not know a whole lot about this, but he may know more of where you could start testing to figure out where to look.
