My first problem was that playing videos made everything freeze - totem was using almost all my cpu power. To solve this I installed nvidia drivers with

sudo apt-get install nvidia-###

Where ### was a number I found using http://www.nvidia.com/Download/index.aspx (for my card Geforce 630M).

This seemed to work. Video playing no longer froze my laptop (which is an Acer Aspire V3-571g if it matters). However, when I connected a second monitor I got some issues. Half of the second screen would be "cut off", only showing black. Entering nvidia-settings only showed the laptop screen

To solve this I found various questions and forum threads suggesting to do install nvidia-current instead. I did that, and ever since the GUI hasn't worked. I've tried things like

sudo apt-get purge nvidia*

and I've tried removing that /etc/X11/xorg.conf file - nothing has worked so far.

Any suggestions on what I can do?

Edit: I'm getting "Unable to connect to X server" now, when I go into terminal with ctrl+alt+F1.

UPDATE: I didn't manage to solve the problem, and in the end I just reinstalled Ubuntu.

"Ubuntu 15.04 seems to have an issue with nvidia drivers." This is a common problem...

First, lets get Ubuntu to a 'clean' state, without any nvidia drivers installed:

sudo apt-get purge $(dpkg -l | awk '$2~/nvidia/ {print $2}')

Next, let's remove the x-server error - follow this guide.

Now, we'll try to set up the Nvidia GT 630 drivers:

sudo apt-get install nvidia-304 nvidia-304-updates

If it still doesn't work, then try upgrading your kernel

sudo apt-get install linux-generic

And try again...

You can install the latest NVIDIA drivers by adding the new PPA to your system.

To do so:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update && sudo apt-get install nvidia-355

And as OMG! Ubuntu! say:
Remember: if the PPA breaks your system you are allowed to keep both halves. ;D
