but in fedora its only have 256mb, so im triying to get more vram for the gpu changing it in the xorg.conf and also change the accelmethod to sna in the devices section:

Section "Device"
    Identifier  "Card0"
    Driver      "intel"
    BusID       "PCI:0:2:0"
    Option      "AccelMethod"  "sna"
    VideoRam 1735680

but they no work, the 256mb of memory for the gpu persist after restart i check in terminal and not work

bash-4.2$ lspci -v -s 00:02.0
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) (prog-if 00 [VGA controller])

Hi! Fedora 17 is no longer supported. I suspect from the age of this question that the issue is no longer present, but feel free to post a question again if you have updated to Fedora 19 or Fedora 20 and you are still having trouble.
