Bug#551512: [metacity] Also meet this bug, more info about it

[Jean-Louis Biasini]

Package: metacity
Version: 1:2.28.0-1

--- Please enter the report below this line. ---
Hello and thanks for your work !

I'm using a mixed squeeze/sid system. I also meet this bug. It started for me after I upgrated a few package to Sid:
gnome-power-manager
gnome-session
gnome-session-bin
Which cause also those new packages to be installed:
devicekit-disks
devicekit-power
libatasmart4
libdevkit-power-gobject1


1) Downgrading / uninstalling those is enough to get rid of the problem, so it's definitively in one of them...

2) I' ve got the very same error in my .xsession-errors (in the very same language ;), which claims (translation) that there is already a windows manager running on the screen 0 and that
we should try the --replace option

3) The very same command stop the problem :
>Killing metacity works fine (no process taking up cpu power anymore)
>but... metacity does not restart automatically.
>A metacity --replace & gets it working fine. 

Furthermore, the command "compiz --replace" make the problem appears again !!

then:
>I'll investigate those errors later. 
>I had an nvidia patched kernel with compiz and stuff gnome desktop before upgrading to 2.6.28 in september and now 2.6.30 ... there might be some conflicting entries - compiz vs metacity

Your are definitively right this is a conflict between compiz and
metacity. Could it be gnome-session that keep on starting metacity
without checking if we are already using a windows manager?

cheers,

Jean-Louis
