Hi!, I just do a fresh fedora 21 install, before I had fedora 21 (but updated from 20).

My laptop is a Rv415-A0ACL. The problem: Fedora doesn't recognize my screen and the maximum resolution is wrong

Using xrandr

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
1024x768       0.00*

The maximum resolution of my laptop is 1366 x 768, I don't have any Xorg configuration file under /etc/X11 so I don't know how to continue to solve my problem.

I don't think X actually needs that file any more but will use it if it exists. The most recent version on my desktop hasn't been changed since August 2013. BTW, the file's name is xorg.conf, not Xorg.conf and everything in Linux is relentlessly case sensitive, so it's possible that you're just mistyping the name. Also, it's possible to create the file manually if needed; check with man xorg.conf for details. If you do create one, you'll need to log out and back in to try it. (If it doesn't work well, log into a CLI console to rename it.)

I try to create it using Xorg -config, (X-server closed with init 3) and it throws segmentation fault :/

Well yes, it would. Xorg -config is used to specify the config file. What you need is Xorg -configure which will write a new xorg.conf, but must be done as root.

My mistake, I was using Xorg -configure

That's OK; tish happens. More important is, did you do it as root, e.g., sudo Xorg -configure because it won't work if you don't.
