Configuration

You can create new configuration files suitable for the fglrx driver with the fglrxconfig tool, alternatively you can also use aticonfig to change configuration parameters. Better backup /etc/X11/xorg.conf before using either of the two utilities.

Supported modes for multi-monitor setups

Attached at the bottom of the page you can find the xorg.conf files I use for the various multi-monitor modes that the ATI binary driver supports and also TV-out. A few notes:

• no example for "Mirror" mode, which is pretty useless if you don't happen to have an external monitor matching the notebook's LCD resolution, i.e. 1400x1050, which I don't.
• the external display I use has a max. resolution of 1280x1024, if your monitor supports less be sure to check the HorizSync, VertRefresh, HSync2 and VRefresh2 options.
• I'm living in Europe, hence my TV understands PAL (connected via S-Video), so if you need NTSC or something else, check the TVFormat and TVStandard options. aticonfig run without arguments lists all available values.
• I have configured my input devices (TouchPad, Trackpoint, external mouse) with their special files in /dev/input and not /dev/input/mice. There's a good chance that your file-to-device mapping looks different, so check if you're using the correct device files in /dev/bus/input/devices. Or just use /dev/input/mice in which case you'll lose the ability to configure some settings per device.
