In order for you to get working dualhead on the Matrox G400 in XFree86, requires that you use Matrox's video driver from their website, along with their proprietary Hallib. The mga driver in Red Hat Linux is built with: #define UseMatroxHal NO This is done because Red Hat does not support proprietary drivers, and people using them often file bug reports anyway. In the case of the Matrox driver, it is very often difficult to determine in short order wether or not someone is using the unsupported Hallib or not. Since I wasted counteless hours debugging many problems that were caused by Matrox hallib being used with the mga driver many releases ago, only to find that hallib was being used after having blown a lot of time already, I disabled Hallib support intentionally in order to limit the amount of bogus bug reports being received. Theoretically, we could still get bug reports from people who download and install both the replacement driver plus hallib from Matrox, however for whatever reason - in practice, that has not turned out to be the case. Since disabling hallib support, I have received virtually zero bug reports for mga hardware involving hallib, so this was a successful decision. People using Hallib, need to report bugs/problems they are having directly to Matrox, so that they are able to fix their binary only driver support, as distributions like Red Hat and others can't really do much about problems that occur with such drivers as we do not have the source code to them. Hope this clarifies things. -- Mike A. Harris _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
