This comment is for those novise like me who mainly want a working
system and are not primarilly looking to fix the bug.
I had the described problem after upgrading from Intrepid to Jaunty a
couple of weeks ago. Xorg always over 30% CPU and often over 80%, even
though I wasn't doing anything.
Running Dell Latitude E6400, 4 gig memory etc. I did try to kill power-
manager and settings-daemon without any result. No vino-server running.
The behavior disappeared when I downgraded all xserver-xorg-<whatever>
packages back to the Intrepid version, and now the system is faster than
ever:-)
Since you who will go for this solution probably are as novice as me I
will outline just how I did the downgrade (which might not be the
standard way, I don't know).
edit the file /etc/apt/sourses.list (for instance sudo vim
/etc/apt/sourses.list)
Comment out all lines including the word 'jaunty' (put # in front of the line)
#deb http://fr.archive.ubuntu.com/ubuntu/ jaunty main multiverse universe
restricted
#deb-src http://fr.archive.ubuntu.com/ubuntu/ jaunty main multiverse universe
restricted
#deb http://fr.archive.ubuntu.com/ubuntu/ jaunty-updates main multiverse
universe restricted
#deb-src http://fr.archive.ubuntu.com/ubuntu/ jaunty-updates main multiverse
universe restricted
add the following line (probably overkill with multiverse universe etc., I
don't know)
deb http://fr.archive.ubuntu.com/ubuntu/ intrepid main multiverse universe
restricted
save the file and do
sudo apt-get update
run aptitude (or your favourite package manager) and downgrade the following
packages, including their dependencies (in my case 34 dependencies):
xserver-xorg
xserver-xorg-core
xserver-xorg-input-all
xserver-xorg-video-all
remember to uncomment the sources.list file and run 'sudo apt-get
update' to reset jaunty repositories (and do not update xserver packages
as suggested).
