Thank you. I had seen that in my searches. However, it's 64 bit related. I'm on 32 bit systems. It also gets ATI drivers not provided by CentOS - antithetical to a subset of my goals. It was solving a different problem, unfortunately. He was trying, IIRC, to solve the problem of spanning desktops. My eventual goal includes that. But step 1 is to try and get both working. I would *like* to stay as much CentOS "pure" as possible, allowing for inclusion of stuff from rpmforge, extras, KB's repo, etc. This is important enough that I will buy a digital monitor to run on a single video card if I must. But as mentioned, I've got lots of older ones I can use. > > Does this help you out?

Maybe this is something I can beg Dag, Axel (never used his repos yet) or the CentOS crew to provide in extras or some such place. I wait a little while and see what develops before I go begging or taking a non-CentOS route. -- Bill
