While I know basically nothing about Matrox cards, the log line [ 26.150] (**) MGA(0): Using "Shadow Framebuffer" - acceleration disabled apparently says that acceleration was deliberately disabled in the config file (i.e. somewhere inside /etc/X11/xorg.conf or inside xorg.conf.d directory). This is the meaning of the (**). Also, AFAIK Gnome3 requires accelerated graphics (at least it did last time I checked). You may be better off trying Mate, XFCE, LXDE, KDE, or some lightweight window manager without a full DE.
