Every time I log in, Unity switches to 2D instead of 3D.

This is what I've been trying so far:

  • Install proprietary drivers NVIDIA.
  • unity --reset
  • Install compiz effects
  • Choose "Ubuntu" instead of "Ubuntu 2D" on login screen

I've tried to reinstall Ubuntu several times with the same result, but I've noticed that on the live cd/usb Ubuntu uses Unity 3D. But after the install it switches to 2D. I don't know what to do. Can someone please help me out here?

My computer is a Asus U35J.

First off, I highly recommend that you put updates on, so open up a Terminal (Dash->Terminal) window, and type in it:

sudo apt-get update
sudo apt-get dist-upgrade

Then reboot. If you still have problems, try this in a Terminal window:

sudo apt-get install unity unity-scope-musicstores unity-common unity-place-applications unity-lens-music unity-place-files unity-lens-files unity-services unity-greeter unity-asset-pool unity-lens-applications unity-lens-gwibber ubuntu-desktop compiz compiz-core

Then reboot.

I had this happen to my computer. Here is how I fixed it.

sudo apt-get install unity #to make sure it's installed

rm -R .config/compiz-1 .compiz-1 .gconf/apps/compiz-1 .gconf/apps/compizconfig- #delete any bad config files

unity --reset # reset unity
sudo reboot # reboot computer

And if it does not work, then I do:

sudo unity --reset # reset unity as root might not be a good idea but it worked for me

sudo reboot # reboot computer
