This might be a known driver/xorg issue. Various hardware either don't work, or gets slow if the framebuffer exceeds 2048 pixels (width/height/something). I'm not sure what the plan with that was, if that could be fixed still in xorg, or only in Wayland. I think it was fixable in xorg, but I'll have to check. In any case, the obvious status is that at the moment some people cannot run GNOME 3 and they have to rely on fallback mode. Debian suggested a method to detect this during installation time. I don't expect GNOME 3 to suddenly be good enough for everyone in 3.8. This as many of the causes are not due to GNOME (bad drivers). -- Regards, Olav
