It appears your monitor is not telling the kernel what resolutions it
supports. This might be a bug in the monitor's firmware, or it might
just be a bad connection. Please try unplugging and replugging the
monitor to the machine. Please also try a different VGA cable. Make sure
it is plugged in securely.
