EDIT - The PPA below works, however it didn't solve my tearing issues.
EDIT 2 - I've just realized I should have worded the question better, rather than copy-pasting it from where I had previously posted it. I'm making some light edits to the text below.
FINAL EDIT - Apparently there's currently no way to eliminate tearing in videos with my setup (Intel + nVidia GPU), according to some of the posts here. They seem to be working on it, but it might be a couple of years.
Nonetheless, the PPA below should be fine if you need your GPU for gaming purposes.
(Sorry for the wall of text, skip to the last paragraph if you want a tl;dr)
I use eOS Freya and a GT 740M (in addition to an integrated Intel GPU).
I had previously tried to use the proprietary driver recommended under Additional Drivers (i.e. 352-update, which seems to be quite outdated), but always experienced heavy tearing and worse performance than when using the Intel GPU with Nouveau. Also, the graphic version of nvidia-settings had, oddly enough, less options than it was supposed to (at least compared to screenshots I saw).
Fast forward some months, I'm back at my quest of breaking free from Windows' chains, and am therefore trying one again to get my GPU to work properly, at least enough to play movies as smoothly as I can on Windows.
So, I'm wondering whether installing the latest version of the driver from a PPA might help. After a bit of googling I found this PPA and I was thinking of using
sudo apt-add-repository ppa:graphics-drivers/ppa sudo apt-get update sudo apt-get install nvidia-364
Is that a good idea? Also, the PPA in the link seems to contain other packages: Vulkan, nvidia-prime and nvidia-settings; the last of these was installed automatically back when I used Ubuntu's recommended driver, if I now use this PPA do I have to install it manually or will the above command install everything I need?
