X failure on ibook G4 [SOLVED]

[pyhxr]

background of problem
===============
I'm actually reading other peoples post on similar issues. I had X working and running xfce4. I did some modifications to the kernel that didn't work. Following the instructions in http://wiki.gentoo.org/wiki/Kernel/Upgrade on sanitizing sources ( cp .config .confi~ run make distclean then mv .config~ .config) I realized I should have verified it actually made a copy, for whatever reason it didn't. Anyway
I made a new kernel and now I can't seem to get X working

problem
=====
X doesn't work, here are the relevant logs.

my /etc/conf.d/modules has

I've tried numerous things like disabling open firmware frame buffer
changing modules to built in components of the kernel
recompiling xorg-server

I will check back tomorrow for replies, been reading and fiddling with this for about 16 hours now so I'm getting distracted.

(Side note, I had most of my problems resolved, with the exception of not being able to connect to WPA2, and sound--which I think the answer is to not use OSS if you want Alsa. I run a light-weight browser called Dillo so I'm not interested in Flash, or Java. -- I know some use minitube to watch youtube. And I am working on how to patch gr-baz into Gnuradio. If you have special knowledge of any of those things please dm me with a link or comment as it would be off topic)

Thanks in advance

Hi
For comparing with what used to work, if you have something at
/proc/config.gz
while your working kernel is in operation you just have to zcat it.

Thanks for the prompt reply.

Running diff on /proc/config.gz and my current .config shows it to be exactly the same. So I did not understand you, or I have wiped something that was there before.

this is the output of Xorg configure command. In the seg fault right after the backtrace -- would that mean that it failed to find those specific libraries? /lib/libc.so.6. Im going to read the Xorg man page again and start Googling all the EE messages in this output. Since my last post I have recompiled the kernel several times after reading others posts. Nothing yet, probably just having the right combo of voodoo. I'll keep the forum posted if I make any progress. Maybe I need to prune that ati driver! And I haven't read the http://wiki.x.org site yet, that might be a good idea. Oh and this is the first time I realized there is a /root/xorg.conf.new file so I'll go through that. bbl

===========
I also added a line to /etc/yaboot.conf
append="video=radeonfb:1024x768-32@60"
then rand ybin -v and rebooted
--did not help

Try enabling Kernel Mode Setting (KMS). The UMS path is no longer supported in the newer X.org releases.

I made a number of changes, I'm not sure which one was responsible but it startx now works and gets me into my xfce4 session.

I added [*] EDAC
----
[*] EDAC legacy sysfs

[*] DMA Engine Support

------------------------------------------

Got rid of ATI Rage 128

------------------------------------------
Edited /etc/yaboot.conf
append="video=radeonfb:off radeon.modeset=1"
closed and ran # ybin -v

-------------------------------------------

Edited xorg.conf
(which I don't know if this matters at all, but I keep this at
/usr/share/X11/xorg.conf.d/10-device.conf)
Section "Device"
Identifier "Radeon9550"
Driver "radeon"
BusID "PCI:0:16:0"
Option "GARTSize" "16"
Option "AccelMethod" "EXA"
EndSection

--------------------------------------------

So, like I said I'm not exactly sure what particular thing was responsible but if your having the same problem and reading this I would suggest editing the files before making those changes to the kernel.

Also on the line in xorg.conf Identifier "Radeon9550" do a #lspci | grep VGA and look at the end of the line, make sure to use the number you have.

-------------------------------------------
Don't give up, you'll eventually stumble on to something.

Thanks JoseJX I will check that out--didn't see your post until just now.
