All of them should be covered. Is Option "UseFBDev" "off" only for the R128 cards on the Powermac and not for the RV 200 QW (Radeon 7500)? Do I need to connect solely to the mga and then plug into the radeon? Yeah, I see the vert and horiz for the G3. It worked with another monitor. Maybe loading vesa would work? --- On Thu, 10/7/10, Warren Block <wblock@wonkity.com> wrote: <blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> From: Warren Block <wblock@wonkity.com> Subject: Re: Xorg configuration fails on G4 Powermac To: "Super Biscuit" <super_bisquit@yahoo.com> Cc: freebsd-x11@freebsd.org, xorg@freedesktop.org Date: Thursday, October 7, 2010, 1:36 PM <div class="plainMail">On Thu, 7 Oct 2010, Super Biscuit wrote: > I've tried the xorg.conf.new with both the options you suggested and Denise suggested.

AEI should have zero effect on output, since it has nothing to do with that. Just pointing out that it should be avoided. On i386, I see (WW) VGA arbiter: cannot open kernel arbiter, no multi-card support Your Xorg.0.log from the forums post doesn't show that. But it would still be my first guess. </div></blockquote></td></tr></table>
