For the record, I tried 2.6.16-mm1 because i saw that the radeon memory mapping patch had been added to the DRM git tree, which mm includes. Unfortunately, it didn't make a noticable change. (This is with xorg-server and the ati driver from head.) --Ricky <div>On 3/21/06, Thorsten Becker <<a href="mailto:thorsten.becker@gmx.de">thorsten.becker@gmx.de</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Le Jeudi 16 Mars 2006 16:00, Thorsten Becker a écrit: > 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.

If I get everything correct I2C is only needed to communicate with the monitor, so to rule everything out I would like to disable it. But setting the Option "NoDDC" to "yes" did not help. Any ideas?
