That's try and get it through purchasing, or maybe I can try the unlikely idea, since it's still under warranty (we just bought it in Nov!), to see if Dell will replace the card. I have a call into them, and am waiting for the RH group there to get back to me, to see if they have a driver (and maybe lean on them to lean on AMD - Dell leans a *lot* harder than I do). > > A fifth option is to use el5 which uses an older supported version of > Xorg (I do find it kind of ironic that RHEL6 ships with such a new > version of Xorg that some proprietary drivers don't support it - more > the kind of thing you expect to run into on Ubuntu or Fedora than > Enterprise Linux). > I don't think I'm going to rebuild his entire system that way. 6.3 would work, but I'm seeing what I can do to avoid that. <several hours later> I've got it working with radeon. What I've spent an hour or two on is hand-crafting an xorg.conf. He's got two monitors, and rotates them (*sigh*). Everything seems right, except for one detail: I can't drag the mouse from one screen to the next. I have Option "Xinerama" "1", but no joy. Clues? mark "almost there" I've been
