So, after trying to setup Bumblebee, I did mess up a lot of my Ubuntu installations, including installing and taking down Nvidia drivers - resolving mirrored and flipped text issues, and well - I managed to do all that, except that now icons and most of GUI elements are just black and white.

I would guess it's related to Linux-headers - as the problem appeared somewhere in that timespan.

Also it could be with 3d acceleration related things? I'm not sure, my first week on Linux.

So - now it looks like this.

I've tried reinstalling both compiz / unity following instructions around. Tried fallback to Gnome (no idea), didn't help either. Any solutions?

Loading CCSM from Terminal gives this:

Gtk-WARNING : Unable to locate theme engine in module_path: "hcengine",

First of all, remove all your Nvidia drivers and bumblebee:

sudo apt-get purge nvidia*
sudo apt-get purge bumblebee*

Then install the current Nvidia drivers:

sudo apt-get install nvidia-current

did both already would rather not install the nvidia-current, since it did break unity/compiz in first place all I have now from nvidia is the nvidia-updates – Roberts Lazda Jul 26 '13 at 23:51
I posted this as an answer because the source of the problem is probably caused by conflicting drivers. I've had a similar problem and this was the solution for me. – Joren Jul 26 '13 at 23:55
