Sorry - this post was rushed.
The reason I say move the config file is that these days the X serveer does a pretty good job of detecting the optimum screen resolution, graphics card driver, mouse, keyboard and other input devices.
If you have a video card which requires a proprietary driver to take advantage of its more advanced features, such as NVidia or Radeon, then you'll have to either:
1. install the proprietary driver through your OS's package management system (preferred)
2. download the linux video driver from the manufacturer and install it by following their own instructions
With Slackware I use option 2, Slackware includes the development environment and libraries required for building a kernel driver module from source, others may not.
