This is the Gnome 3 "fallback" mode, which you get when your graphics card driver doesn't support 3D acceleration as needed by Gnome 3 Shell. Change your driver for your graphics card.
If you need help, run the following command and post output here:
- Code: Select all
inxi -SGxc 0
BTW, it doesn't matter that you installed 32 bit on 64 bit
