Thanks heaps - I will work thru this next week and let you know. BTW, to others who were asking, my system has a S3 Trio 64V+ PCI and a SiS 530 AGP card, not a single card that does dual-head. I have got as far as getting Linux to initialize the 2nd monitor, but it's getting it going under X that's eluding me.
