The best way to configure X is to build it from source. Use a net install image and build the system such as:
base -> xorg&alsa&background&synaptic&gui&users -> devices and permissions, tuning.
So I recently started using the latest Kubuntu to try to see past windows. Really I find it to be quite amazing but there's certain things such as not being able to change my resolution from the highest setting and my refresh rate being stuck at 50hz rather than the normal 59hz. I've looked over several guides about manually adding values to system files but these guides seem to be out of date or don't apply for some reason or another. Got the latest drivers.
