Thanks to the help of Mike Harris, I now have Xinerama up an running correctly. I am having one problem though. When running with Xinerama, my qt apps (scribus specifically) look less smooth, like antialiasing is not working, though it is turned on. Scribus also hangs on start related to fonts sometimes when run with Xinerama on. Another thing I noticed was that the fonts section of qtconfig is different whith Xinerama running. This all worked with redhat 9, everything played nicely with everything else. Everything works fine if I turn Xinerama off. Is there something I'm doing wrong, or have I stumbled upon a bug? thanks Scott
