What the ordinary user would like would be for Fedora to set the correct 
resolution on the damn monitor. or at least offer a choice other than 
*really crappy* or *even more crappy.*

I can think of several other Linux Distributions that can do this during 
*the install*. No barriers to leap. No doors to open. No oceans to swim. 
No mountains to climb. It 'just works'.

No distro names for politeness. Ask I and will post names. I can think 
of three that I know for a fact that do this.

As good as it is there are things at which Fedora flat out sucks!
