I am actually having the exact same problem. I built the radeon driver from the ati-1-0-branch last night, but that didn't seem to fix the problem. I'm currently in the process of building xorg-server and the radeon driver from the trunk. We'll see if that fixes anything... --Ricky <div>On 3/16/06, Alex Deucher <<a href="mailto:alexdeucher@gmail.com">alexdeucher@gmail.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> On 3/16/06, Thorsten Becker <<a href="mailto:thorsten.becker@gmx.de">thorsten.becker@gmx.de</a>> wrote: > Xorg 7.0.0, kernel 2.6.15-gentoo-r1 > > Hello, > > To create a dual seat system I bought a Readeon 7000 PCI card for my Dell > Dimension 4550, which has a Radeon 9700 already installed.
