Hi,
i've just downloaded F17 and i tried to install it on my computer x86 having a nVidia 8800 GT video card. after seeing only the logo at boot process, now everything i can see is a black screen :( and the Led of my monitor is blinking so it means no video signal. is there any compatibility issue with f17 and nvidia 8800 ? thank

Sounds awfully like what I've had to deal with: GRUB running at the highest resolution that the graphics card could generate, regardless of whether the scan/refresh rates were compatible with my monitor (which it wasn't).
I don't know how you can fix that if you can't, at some stage, get to see a display. I was lucky enough that once GRUB had finally booted up an OS, the OS did run at a suitable rate, and I could edit the configuration to change GRUB's resolution.
In the /etc/default/grub file, I added this line:
GRUB_GFXMODE=800x600
Then ran the "grub2-mkconfig" command to regenerate the config file used at boot time.
If it's X, itself, running at the wrong resolution, after GRUB has handed over, and if Xorg hadn't been crippled, years ago, you could have pressed CTRL ALT + or - to change resolutions on the fly, until something worked.

Hi Tim,
in fact this problem occurs with Fedora 17, Ubuntu 12.x but not with Mandriva 2011...strange isn't it ? so today i can install F17 as i wanted on this computer and i must stay with this horrible Win7... previously it was possible to boot on Fedora, ubuntu and later on change screen resolution, but now it is automatically detected and X use it :(
