More consistent way would be to just check the Linux kernel version. Most distros are going to be running the default kernel with everything enabled, so you shouldn’t need to worry about specific kernel options being disabled, unless you’re using something really esoteric and not meant for general desktop usage. If you need 3rd party (nvidia) drivers, nouveau works out of the box, and should at least get you to the point you can install the proprietary driver, should you wish to taint your kernel in that way :'(
