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 :(
