Anyway, I will google it and do this tracing thing. And it works if i use "xaa" instead of "exa". However, I happen to use "twm" instead of xfce4, and there was no error! And if I start xfce within twm, there's no error too. Now i am extremely confused and not sure if it's an error from X server or the wm. But since the same xfce4 worked on 6.8.2 and <a href="http://6.8.99.16" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">6.8.99.16</a>, I would prefer to say it's the X server...(correct me if I'm wrong), otherwise I have to send a bug report to a different place. :)<div> <div>On 10/27/05, Benjamin Herrenschmidt <<a href="mailto:benh@kernel.crashing.org" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> benh@kernel.crashing.org</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 Wed, 2005-10-26 at 23:38 -0400, Chao Cao wrote: > Hi, > I just compiled Xorg 6.9 RC1 on my laptop (IBM T42 with a radeon > 7500), and tried to get it running with my external LCD panel (DELL > 1905FP).

Can you make sure you build with -g (to get debug symbols) and try to catch this in gdb ? I would like to know more precisely where it crashes... Also, please open a bug report on <a href="http://bugs.freedesktop.org" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> bugs.freedesktop.org</a> and assign or CC me. BTW. Does it work when using XAA instead of EXA ? Thanks; Ben. </blockquote></div> </div></blockquote></div>
