Configuration

You can create new configuration files suitable for the radeon driver with the text-based xorgconfig tool or run

X -configure

to let X.org probe your hardware and write a configuration file, alternatively you can also use the graphic application xorgcfg to change configuration parameters. Better backup /etc/X11/xorg.conf before using either of these 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 radeon driver supports. A few notes:

• the external display I use has a max. resolution of 1280x1024, if your monitor supports less be sure to check the HorizSync, VertRefresh, CRT2HSync and CRT2VSync options.
• 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.
• TV-Out is currently not supported by the opensource radeon driver, use the fglrx driver if you need this feature.
• real dual-head support (as in two seperate independent screens) seems to be broken at the moment, see bug #332548 in the Debian bug tracking system.
