Description Michael Biggins 2005-03-19 10:40:54 UTC

Gentoo kernel 2.6.11-r4
XOrg-X11 6.8.2-r1
Flags:
   -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

For some cause unknown, X seems to enter a closed loop and concequently tries to
eat 100% of the CPU time causing the system to become largely unusable. Occours
in X process.

Another data point:

This happens for me as well, also on gentoo.

kernel: 2.4.28
nvidia-glx-1.0.6629-r1
nvidia-kernel-1.0.6629-r1
xorg-x11-6.8.2-r1

flags:-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

killall -9 X is the only way I've found to regain the use of the system.

Comment 2 Michael Biggins 2005-03-25 03:51:03 UTC

ctrl+alt+backspace works just as well ;) 
 
Perhaps this should be in gentoo buglist as well as just xorg's?

Comment 3 Mr. Bones. 2005-03-25 09:25:45 UTC

I believe I have tracked the cause of my problems down to the line 

Option "RenderAccel" "true"

in the device section.  I think I added that without reading the warning in the
Nvidia docs.  I can't reproduce the problem after commenting out that line.

Comment 4 Chris Lee 2005-07-04 16:09:36 UTC

Michael, are you using the NVidia driver?

Comment 5 Michael Biggins 2005-07-05 15:26:51 UTC

Yes - the latest from the NVidia site.

Comment 6 Erik Andren 2006-05-24 06:46:41 UTC

Is this problem still reproducible with a current version of xorg?

Comment 7 Mr. Bones. 2006-06-04 20:26:18 UTC

I can't reproduce it with xorg-7.0.

Comment 8 Daniel Stone 2006-06-04 21:07:04 UTC

closing as WFM as this was an nvidia problem, since fixed
