Description:
After updating to GNOME 2.26 Xorg causes 100% CPU load. I couldn't determine a exact part of GNOME causing this. The problem also occurs when GNOME is used with default configuration under a new user account.

Package versions:
GNOME 2.26
X.Org X Server 1.5.3
This task depends upon

I just want to confirm this problem.
video-driver is nvidia

The problems seems to be independent of the used video driver. It makes no difference wheter I use nvidia or nv. In the BBS I also read that a intel user is affected.

Updating to X.Org X Server 1.6.0 is a possible workarround.

I can confirm this bug, it exists regardless of which video driver is being used. It also appears with a clean config (I created a new user 'test' which experienced the same 100% CPU bug).

I can confirm that upgrading to X.Org X Server 1.6.0 fixes the bug.

In #archlinux I heard that downgrading gnome-session should fix the problem also.

I've tracked it down to this commit in gnome-session:

Which is fixed in xorg-server with this commit:

Same problem here. Waiting for 1.6 to hit the core repository...

Same problem here, after upgrading to gnome 2.26 my laptop melted into to a little puddle of plastic.

I have the same issue. Downgrading gnome-session and adding it to IgnorePkg in /etc/pacman.conf fixes the problem.

Here is some more to read about it: http://support.zenwalk.org/viewtopic.php?f=36&t=21775

I got the same problem after GNOME upgrade to the newest version.
I've downgraded gnome-session :

# wget http://ftp.icm.edu.pl/pub/Linux/sunsite/distributions/archlinux/extra/os/i686/gnome-session-2.24.3-1-i686.pkg.tar.gz
# pacman -U gnome-session-2.24.3-1-i686.pkg.tar.gz

And of course I've added gnome-session to IgnorePkg in /etc/pacman.conf such the previous comment.
