Regarding Alans comment about gnome-shell falling back on > 2048 pixel wide displays, I had the same thing with gnome-shell on an nvidia card using the nouveau drivers. So, I guess this might not be specific to i9xx displays. In my case, one symptom was that these errors appeared in Xorg.0.log --- (II) AIGLX: Screen 0 is not DRI2 capable (II) AIGLX: Screen 0 is not DRI capable --- even though the card is DRI capable. I believe this blog entry has the reason: https://jeremy.visser.name/2009/10/no-dri-on-x-org-with-a-radeon-check-your-virtual-size/ Quoting from that page: "Because of various technical reasons, when the Virtual size is too big (which, evidently, 2048×2048 is), DRI gets disabled" I started seeing this error after I upgraded to a new nvidia card with more memory. After the upgrade my default Virtual size went to about 8000x8000 and gnome-shell would only run in fallback mode. Strangely, the problem went away when I switched to the closed source nvidia drivers, and gnome-shell works great.
