Ubuntu 14.04 LTS randomly freezes (graphics/unity only)
This may be the cause of your problems: Nvidia-Prime Freeze
Theese two things have worked for me so far; either:
Disable touchpad in: System settings -> Mouse & Touchpad -> "off" and use a regular USB mouse.
Install nvidia-prime
sudo apt-get install nvidia-prime
, find "Nvidia Settings" in dash, and under "Prime Profiles" choose "Intel(Power saving mode)"
The latter disables your dedicated graphics card, but works well for all the day-to-day tasks. Also, this made my computer a lot quieter (and surely less power consuming) which is comfortable when you are just browsing the web anyway...
Hope this helps :)

When I'm just chilling on the desktop or doing whatever, Ubuntu 14.04 LTS will (every 10-20 minutes or so) just randomly freeze. The screen just stops, I can't see my mouse move, etc. However, I can Alt+Ctrl+F1 into a tty terminal (though it's not much use).
However, I noticed that if I close my laptop's lid, re-open it, then enter my password to unlock the lock screen, everything is fine.
What is going on here? How can I fix / stop / prevent this?
Note: My laptop has an nvidia-optimus setup, but Ubuntu 14.04 LTS automatically recognized it and had the nvidia drivers applied.

Hme almost 10 yearsBy tapping the windows button (dash?), and then simply start typing "nvidia" a green icon named "NVIDIA X Server Settings" should become visible.
