linux---2 monitors

I have tryed,.. well with no succes,.. to install 2 monitors in linux 7.1 profesional , Kernal 2.2 something.... anyway... I have :
1 elsa victory 2 and a dimond card.
the first agp and second pci.

the Dimond is a old card... :(

althoug linux finds it and also the other, under sax2, it runs untill to the point I have to test it,... on the test it blocks,....the Diamond card,.. and the monitor is stoped.

I could imagen that this lies with the card ( although in windows98 it works good), ( but that has nothing to say),..hhmmmm,... any other thoughts or advice??

:)

thanx a lot hope to get some nice news!!!

love yas and leave yas!
