Can I remove Unity 2D safely?
My computer can run Unity 3D comfortably, and I don't really want Unity 2D as a fallback. Can I remove it without breaking my system?
Solution 1:
Yes, and you'll save 205KB of diskspace. sudo apt-get remove unity-2d.
Solution 2:
I wouldn't recommend it. What if your video card fails and you use an old spare part to get something done in a pinch, and it doesn't work with 3D right away? Or even just something goes wrong with configuration on a future update?
I suppose you can apt-get it again, but why the hassle?
