I'm new to Linux and I've just installed mepis 6.0, and can't change the refresh rate. At 1024 x 768 I only have one option of 71 hz. How can I set my particular brand and model of monitor, and where can you see if you the correct driver for the graphics card is installed? I believe it is a nvidia riva tnt something, on an athlon 2200+
thanks,
Mike
