CPU Accelerated Graphics
Systems with older or no graphics acceleration devices can have accelerated desktop environments using LLVMpipe technology, which uses the CPU to render graphics. LLVMpipe requires a processor with SSE2 extensions. The extensions supported by your processor are listed in the flags: section of /proc/cpuinfo
The last sentence discusses SSE2 extensions with flags. Is this a prerequisite? If the user can visit /proc/cpuinfo, then presumeably Fedora is already successfully installed and working Perhaps a very terse (brief) discussion of cpus and capabilities is where to introduce SSE2 and /proc/cpuinfo. Then follow with the above paragraph.
