  • Radeon Open Source and modeline

    I see that with new versions of this driver the Modeline command in xorg.conf doesn't have effect anymore.
    With some of these versions xvidtune doesn't apply the settings.
    Is there a workaround or any fix?

      You can still specify modelines, it just works a little differently for randr 1.2 drivers. You can either specify the mode on the fly with xrandr or specify the modeline in a monitor section of your config linked to the output you want to use it with.

      Code:
      xrandr --newmode my_mode 63.50 1024 1072 1176 1328  768 771 775 798 -hsync +vsync
      xrandr --addmode VGA-0 my_mode
      See this page for more on xrandr config file information:

        yes but that do the thing dinamically, I needed it permanently, so I discovered that modeline still works with the option PreferredMode.
