F10 hangs during installation (screen freezes at some point), and never completes. On the same machine, F9 could install OK except that the install selected "ati" Xorg driver never worked and I had to revert to "vesa".
I understand that F10 now activates graphics within the kernel and that could be the reason of such freezing in the install phase.
I finally managed to complete anaconda install using "text" parameter on the install command line prompt to do a text install (press tab, add the word text)... This confirm a serious problem with HD3200 graphics chip embedded in my Gigabyte MA78GPM-DS2H.
Thereafter the machine boot in runlevel 3 (no X). Trying to start X (startx command) freezes the machine. /etc/X11 contains no xorg.conf so I suspect the startx to try to build an xorg.conf with "ati" driver. So I created my own xorg.conf with "vesa" driver. Startx now works. Replacing "vesa" with "ati" freezes the machine. So "ati" driver seems to be the problem.
By the way system-config-display has gone from the F10 install DVD. It was a useful tool to build an /etc/X11/xorg.conf from scratch (this helped me to make F9 work on that MB)
Hope this will help some others with AMD chipset (780G + SB700) to have a better F10 experience than mine...
P.S. Another interesting point is that the proprietary ATI driver fglrx despite working on F9, developed problems: periodically the computer freezes for a few seconds, especially when interacting with the display... Playing any sort of video produces screen flickering (only on the video screen portion). But one can configure a very nice looking desktop with effects on and in Full HD mode (1920x1280),
