intel(0): Not using mode "1280x1024" (hsync out of range)

So please define your xorg.conf in order to allow X chose 1280x1024.
Section "Monitor"
     Identifier "VGA"
     HorizSync 20-170
     VertRefresh 60
     ...

Get rid of your xorg.conf, then you will be fine. the hsync of your 1280x1024 mode is 64.0khz, but you set "    HorizSync   30-60" in your xorg.conf...

reopen if it still doesnt' work.
