I have tried to disable the ShadowFB by setting Option ShadowFB "false", and now I get a signal 11 when I startx. The new log is at <a href="http://geodyn.psu.edu/xorg_errors/Xorg.0.log.sig11">http://geodyn.psu.edu/xorg_errors/Xorg.0.log.sig11 </a> <div>On 10/13/06, Michel Dänzer <<a href="mailto:michel@tungstengraphics.com">michel@tungstengraphics.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 Tue, 2006-10-10 at 10:18 -0400, Tom Moyer wrote: > I have been trying to get <a href="http://X.org">X.org</a> to work on several IBM RS/6000's > lately and have had no luck.

Note that the fbdev driver in 7.1 is known to have issues with ShadowFB (see e.g. <a href="https://bugs.freedesktop.org/show_bug.cgi?id=7691">https://bugs.freedesktop.org/show_bug.cgi?id=7691</a>). If the problem persists with that disabled, please also provide the output of fbset -i. -- Earthling Michel Dänzer | <a href="http://tungstengraphics.com">http://tungstengraphics.com</a> Libre software enthusiast | Debian, X and DRI developer </blockquote> </div>
