Just upgraded to 14.04 and started to experience random freezes. Only workaround in to ctrl+alt+tab+F2 and ctrl+alt+tab+f7 to unfreeze laptop. Or hard reset. Currently happens when browser is open (occures for firefox, chromium). Switching from nouveau to nvidia proprietary drivers (tried both stable and updated version) didn't help.
WORKAROUND: Switched to Intel card and no lockups.

I concur. Since Ubuntu 13.04, I have seen quick lockups with both the nouveau and nVidia drivers in all the Ubuntu and derivative variants I have tried (ubuntu, kubuntu, xubuntu, Mint, Mint KDE, etc). My original problem occurred when I upgraded from Ubuntu 12.10 to 13.04. Since then, that kernel/nvidia driver combo has been completely unusable. I can use Mint LMDE (Cinnamon) which is kernel 3.10 (I think?) and Korora/Fedora 20 (which is kernel 3.13.10) even though resume doesn't work there, so it seems that kernel 3.13 breaks something graphical. I dread the day that LMDE "upgrades" to kernel 3.13, because I expect things to break then and I'll be left wth Windows 7 as my only working alternative since I can't find a Linux distro (out of the hundreds available) that just works.
(FWIW, Solyd* both also both fail miserably with the same problem. The problem is clearly upstream of Ubuntu as it affects a number of distros with that kernel/nVidia driver combo.)
It's a pity that some things that used to work no longer do so, and the people that break them don't seem to care. I've ssen many responses on these bug report sites where the user is being blamed for the bugs, or being told "that's normal; get over it". This is just not bloody good enough.
FWIW: nVidia GeForce GT240.
