I have a Ubuntu 12.04 image on a flash drive. When I boot from that, I'm able to resize the icons in my launcher, and windows snap to half the screen. I assume this means that I'm running ubuntu 3d.
I just upgraded from Ubuntu 11.04 up to 12.04 (not a fresh install). Running the Ubuntu 12.04 installed on my hard drive, I am not able to resize the icons in my launcher nor snap the windows to half the screen. This command seems to say I'm in Ubuntu 2d, even though I have tried logging out, and specifically logging in with the regular Ubuntu rather than Ubuntu-2d.
$ echo $DESKTOP_SESSION ubuntu-2d
How do I get the Ubuntu installation I have on my hard drive to act like the one I ran from the flash drive?
Update: Here is the output of the debugging commands, as requested.
$ cat /var/log/Xorg.0.log

If anyone needs anything else, let me know. I don't really know what is important for this issue.
