Check that the video hardware has this, and also that it is enabled.

It should support hardware video acceleration because my wife's computer's CPU is manufactured a year earlier, named Intel Ivy-Bridge (accompanying chipset is Intel H77) and Gnome3 works flawlessly on my wife's computer. To check if hardware rendering is enabled: glxinfo | grep Yes Should output a line like this: "direct rendering: Yes" If Gnome went into 'fallback mode' for whatever reason, it might 'stick' in the session. Have you tried setting a different 'session' from the GDM login manager? Options usually include 'default', 'gnome', 'fallback'. I can't remember the exact names, it's a while since I checked.
