    Default intel hd graphics

    hello.
    I'm nzew to linux and I recently installed backtrack5 r2 on my aspire 7542z notebook.
    it's working and looking great but for 1 thing:
    it moves very slow... it's like lagging, especially when I move a window. i used to get this problem on windows when i didn't have my video drivers installed.

    my notebook uses intel hd graphics for video procesing.
    how may I fix this problem?

    thank you!

    I managed to fix the problem by replacing the argument of GRUB_CMDLINE_LINUX_DEFAULT with "i915.i915_enable_rc6=1 i915.lvds_downclock=$clock=1 i915.i915_enable_fbc=1 pcie_aspm=force"
    the line should look like

    GRUB_CMDLINE_LINUX_DEFAULT="i915.i915_enable_rc6=1 i915.lvds_downclock=$clock=1 i915.i915_enable_fbc=1 pcie_aspm=force"

    this file is located in etc/default and it's name is grub

    after you edit the file, save it, then type update-grub in the terminal, and then restart.

    Remember to take a backup of the file, before you edit it.
    That way you don't screw anything up ;-)
