I'm running 12.04 on a Gateway LT4004u netbook. My graphics card is an integrated Intel GMA 3600. I'm not sure whether or not it supports 3d, I have been unable to find any information via Google or Gateway's website.
I installed Gnome3 using the apt-get commands in the terminal. When I rebooted and ran "Gnome Shell" it opened up classic mode. I thought that my cursor might have slipped the first time, but on multiple retries logging in under gnome shell would open the gnome classic desktop. I even uninstalled Gnome Shell and reinstalled it with software center, but I still have the same problem.
I was wondering if this might be an issue with my graphics card? Any help would be much appreciated, thanks!
