You probably don't have your XF86Config file set up for doing xinerama. You need to have both cards defined, both monitors defined, and you need to have sections which specify which monitor is bound to which card, and finally you need to have a "layout" section for defining how the monitors are arranged with respect to each other (i.e. whether the second screen is left of the first one, or right of it, or above it, or whatever). The Xinerama HOWTO <http://www.linuxdoc.org/HOWTO/Xinerama-HOWTO.html> tells you how to do all this. If you still can't get it to work after using the HOWTO, then post your XF86Config to the mailing list and perhaps someone can tell you what you're doing wrong. > i didn't find any tool that knows how to do that in RH (Xconfigurator doesn't > either) and the most weird thing is that the "use xinerama extention" option > that used to be in Kcontrol in mandrake, is not here. That's not terribly surprising. Kcontrol is designed to be extended with modules, and obviously Mandrake included a kcontrol module for configuring XFree86, while Red Hat didn't. -- { Daniel Jacob Pearson | compare foods } { <[EMAIL PROTECTED]> | -- jeff covey }
