When I start up the xserver the entire system locks up.  My virtual consoles
freeze and lock up.  I cannot ping the machine any longer.  This is all on an
Apple Powerbook G4 17in model.  The machine basically locks up/

It appears that there are multiple problems happening:

At this point your log file ends, implying that enabling DRI is causing the
machine to hang.  Are you using the Red Hat official kernel for FC5, as
supplied by Red Hat?  We have disabled R300+ DRM support, so the kernel
modules should not even load at all.

Please try commenting out the line:  Load "dri" in the config file, and
rebooting and restarting X again.  Does that allow the server to start?
Comment 4 Alex Karasulu 2006-03-22 12:27:38 EST
I have done that already and it still hangs even with DRI removed.  The server
appears to start since I see some vertical lines on the display in the right
hand side.  However the machine is completly hung still.
Comment 5 Ken Bauer 2006-03-22 18:37:42 EST
Confirming same behaviour on the most recent G4 powerbook 15"

I was also forced to install in text mode (but always had to deal with that in 
my previous life of working on thinkpads).

Comment 6 Alex Karasulu 2006-03-22 20:51:47 EST
I forgot to mention that I too had to install in text mode.  Sorry about
forgetting this important point but I guess you could infer that.
Comment 7 Mike A. Harris 2006-03-23 23:32:13 EST
Please report this issue to X.Org developers by filing a bug report in
the X.Org bugzilla located at http://bugs.freedesktop.org in the "xorg"

Once you've filed your bug report to X.Org, if you paste the new
bug URL here, Red Hat will continue to track the issue in the
centralized X.Org bug tracker, and will review any bug fixes that
become available for consideration in future updates.

Setting status to "NEEDINFO_REPORTER", awaiting X.Org bug URL
for tracking.

This looks like the same bug which was posted 1-21-2006:

Comment 9 Frank Arnold 2006-03-24 11:36:51 EST
I don't think the freedesktop bug is related to this issue. I've followed the
whole development cycle with my PowerBook (PowerBook5,6 - Radeon 9700) and had
no major problems. Even GL worked as long as it was enabled. Todays 'yum update'
broke it.

Up to including xorg-x11-server-1.0.1-8 everything is fine for me.

With 1.0.1-9 I could login once. After logout the screen vanished from solid
light red to grey and Xorg used a lot of CPU. However, I could switch to a VT at
least. This behaviour is known, but occured only when switching to a VT and back
to X.

The current cvs snapshot in devel is totally broken. It doesn't display
anything, although the graphical startup seems to work. Not sure if it's an
ati-drv or server problem.

Working config. Comment out the line --Load "dri"-- to freeze the system.

Forget about my last comment. I meddled with different configs yesterday and
can't recall what I've done there.

Today I tracked it down further. All package versions seem to behave the same
way. If the module "dri" isn't explicitly loaded, everything hangs.

I'll attach a working xorg.conf (a little bit cluttered, and needs some
modification for 17") as well as good/bad logs from a setup with current devel

Comment 13 Gavin Scott 2006-06-06 21:08:35 EDT
This is a me too comment.  I have the last rev 15" powerbook g4 (PowerBook5,8).
 The FC5 gui installer hung.  After doing a "linux text" install and yum update,
running system-config-display hangs the system completely.  I will attach the
log from that.

As a possibly unhelpful data point, Ubuntu Dappy Flight 7 had this problem as
well but the Release Candidate (and final release) do not.

FYI upgrading to xorg-x11-server-Xorg-1.1.0-3.ppc.rpm and
xorg-x11-drv-ati-6.6.0-3.ppc.rpm from rawhide resolved the issue for me.

Thanks, closing as fixed in "RAWHIDE".
