I'm sure this question has been asked before, but I can't seem to locate it on this website, so here goes.
My gnome3 does not look like it should. When I first installed
gnome-shell, it worked, but after rebooting once, the interface looks like the classic gnome interface.
I'm looking for an answer to why this behavior exists and how to fix it.
Note that I had this problem before, and I was able to (accidentally) get it to work in Ubuntu 11.10, so it's not likely to be a hardware error.
I'm running Ubuntu 12.04 32-bit on a HP Pavilion dv6. My Settings > Details > Graphics reads "driver: unknown, environment: fallback"
That does display the gnome3 bar at the top, along with the Super key functionality, but the windows go all flashy and it's hard to navigate between windows. This is the output in the terminal.
