Video driver is nouveau Problem began upon upgrading of xserver-xorg-core_1.17.1-0ubuntu3_amd64 and xserver-xorg-common_1.17.1-0ubuntu3_amd64xorg to xserver-xorg-core_1.17.1-0ubuntu4_amd64 and xserver-xorg-common_1.17.1-0ubuntu4_amd64xorg and was resolved by reverting to the pre-upgrade packages. Apparently random text characters, or parts thereof, would be missing in various applications including the Lightdm greeter, Firefox, Pidgin, Mate-terminal, the Mate panel clock, Unetbootin, and the Mate menu. This occurs both at my monitor's native resolution (1680x1050) and at 1600x1200.
