I know that trying to get more than 2 monitors, or more than 1 monitor on more than one card is a common question around these parts, but I've been futzing with this thing off and on for a month, and this seems like the best place to ask.
I've got the setup described in the title of this post, 64-bit SuSE, 2 ATI Radeon 4850s with the proprietary drivers. I've been working for awhile with 3 separate screens (all under fglrx) but no shared desktop. Acceleration worked great, no issues. I want to switch to Xinerama, 1 big desktop spanning 3 screens (I've got 2 plugged into one card and 1 into the other) Try as I might, I can't make all 3 monitors active. I can only ever have one card at a time active. (So I get my 2 outside monitors, or the one in the middle) I've read that this *should* be possible, but I've stripped about everything I can out of xorg.conf and I'm at my wits end. I'll post it here, and maybe some one can help.
Thanks, guys and gals.
