Use the flags -f and -r for forcing Rage Mobility/Rage LT resp. Radeon/R128 mode. * Not available on Radeon/Rage 128.

You may specifiy more than one command on the command line. An example:

    atitvout pal auto

This command line automatically enables an attached TV and sets it to PAL mode.


PLEASE NOTE: When using the ati driver of XFree 4.1 you should rerun this utility always after having changed the screen resolution with C-A-+ or C-A--. Otherwise the displays may go nuts.

PLEASE NOTE: Not all ATI adapters support all of these commands. Please try them all before complaining.

PLEASE NOTE: Most cards do not allow to activate non attached displays. All calls to atitvout will fail if you try to enable displays which do not show up in 'atitvout detect'.

PLEASE NOTE: Not all adapters seem to support simultaneously using TV and LCD from within Linux. Thus 'lt' may fail, while 'l' and 't' succeed. In this case 'auto' will fail too. In fact 'auto' works only on very few adapters.
