how to specify which head is the primary monitor?

[hylpro]

i have a lcd tv connect to HDMI, and a crt connect to VGA.

ati2600hd, ubuntu8.04

1. first time i install ati 8.11, then upgrade to 8.12, the crt
is the primary monitor, the login screen is on the crt.

2. then i reinstall the ubuntu, and reinstall the 8.12, the hdmi head
became the primary monitor

i have try many method to take the crt as primary monitor but failed.
Modify the xorg.conf : there is no document about the ati driver's option, (but i have seen Nvidia's document). so i failed take the crt back to primary monitor.

These are the aticonfig options:
--swap-monitor
This only works for big desktop setup. This will swap the
contents on the two monitors.
--swap-screens={on|off}
Enable/disable swap heads in dual-head mode.
This option works only in dual-head mode.
Does any of them help?
