<div dir="ltr">Hi,<br> I got this problem today after I did an upgrade.So I tried compiz instead,All these buttons are just ok.<br>So I suspect this may be a problem with metacity.I followed Patrick's suggestions in this thread and reinstalled<br>
all metacity-related packages: <br> apt-get install --reinstall metacity metacity-common libmetacity0<br>then after restart metacity all these buttons come back.<br><br>Later I remembered that dpkg exited abnormally when trying to configure the package debian-reference-common during upgrade.<br>
and it got exited again and again everytime I tried dpkg-reconfigure -a, Not untill I remove this package and dpkg-reconfigure -a<br>again can I install debian-reference-common and configure all other packages that not configured.<br>
<br>So It may be due to metacity not configured correctly? I can attach the dpkg.log if needed.<br><br>Regards,<br>Darren.<br></div>
