not sure where to post for help with this so starting here. just found

i've posted at linuxquestions regarding this esoteric setup but have not
been able to get it to work:

the above thread gives details regarding what's been tried so far. in a
nutshell, i can get one screen of the triplehead2go to display, along with the screen on the other port of the ati card. both display the same image. both display in low res. any help is much appreciated.
