Comment 2 for bug 160215

Thank you for taking the time to report this bug and helping to make
Ubuntu better. Unfortunately we can't fix it, because your description
didn't include enough information.

At a minimum, we need:
1. your ~/.xsession-errors file, /var/log/Xorg.0.log and the output of lspci -vvnn as separate attachments to this bug report
2. are you using gtk-window-decorator or emerald? (you can check this via ps -ef | grep emerald while running desktop effects. Post the output here please!)
Thanks!
