Description Jan Kundrát 2005-04-10 06:08:10 UTC

Hi, using Gentoo, x11-base/xorg-x11-6.8.2-r1, USE flags are "-3dfx +3dnow   
+bitmap-fonts -cjk -debug -dlloader -dmx -doc -font-server* -hardened   
-insecure-drivers +ipv6 -minimal+mmx +nls +opengl +pam -sdk -sse -static   
+truetype-fonts +type1-fonts (-uclibc)-xprint +xv".   
   
Sometimes the CPU usage of process X goes too high - 99% as indicated by `top`,   
sometimes only to about 60%, and lasts on such values for some time. Chances 
for this to happen are higher if konqueror is running, especially with loaded 
"reply to thread" page of vBulettin forum (textarea, input boxes, animated 
GIFs).   
   
Vanilla 2.6.11.4 kernel, xorg 6.8.2, configs will follow. 
 
As the system is still usable, I think I can provide some debugging 
information, just ask.

Oops, forgot to mention grpahic adapter model, altough it's in the log: 
 
Matrox G400, 32MB model

Is this still an issue using a current version of xorg?

Nope, it seems fixed. Thanks for the reminder :).

I'm having similar trouble quite often now with x11-base/xorg-x11-7.1,
x11-drivers/nvidia-legacy-drivers-1.0.7184 and the problems started when I
switched to x11-drivers/nvidia-legacy-drivers-1.0.7184.  X has locked up 4 or 5
times within a 2 week time with 99% CPU usage.

Comment 8 gnuorder 2006-10-30 07:27:18 UTC

I meant to say the problems started when I upgraded to sys-devel/gcc-4.1.1 and
recompiled xorg.  That process upgraded xorg to 7.1 and switched me from
nvidia-kernel/glx to nvidia-drivers.

nvidia report during latest X lockup

Ignore the old xfree86.log

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

I think your issue is caused by something else. I notice in your Xorg.0.log that ACPI fails to open, and then that APM is not even supported by your kernel. At the same time, I also see a lot of different issues relating to nvidia.

If you're still having problems with your setup, you might want to open a new bug against nv, nouveau, or whatever you might be using.

I'm closing this one.
