Fedora hangs driving me nuts, in Windows it works without problems!

Switching off the acceleration or switching to SNA would be the first
try. Create a file named "20-intel.conf" in /etc/X11/xorg.conf.d
containing

Section "Device"
   Identifier "Card0"
   Driver "intel"
   Option "AccelMethod" "SNA"
EndSection

to choose SNA or

Section "Device"
   Identifier "Card0"
   Driver "intel"
   Option "NoAccel" "True"
  EndSection

to switch off acceleration completely. Restart your graphical
environment afterwards.

You may want to boot with "i915.i915_enable_rc6=0", too.
