On my X site I have: The MGA hal is a closed-source hardware access library from Matrox. XFree86 includes the ability to make a loadable module using this library to add features to XFree86's Matrox support. If the loadable module is present it enables TV Out and dualhead for G400 cards (non-G400 dualhead cards don't need it). If it isn't found, an error message is printed about it being missing but it's not a problem unless you need these features. There's some more that having the mga_hal changes, but I wasn't clear on what it was. I know about the drm not successfully initilizing on the second start of XFree86. This is something that, afaik, only occurs with KDE. My guess is that there's something going on with forking that some KDE program does which confuses the DRM. I made a patch for it, but the one person who has tested it so far said it didn't help. I don't know about #2. -- Eric Anholt eta@lclark.edu http://people.freebsd.org/~anholt/ anholt@FreeBSD.org
