ok, found and installed the unity-dbgsym and libnux-4.0-0-dbgsym but that does not change the backtrace, so I assume it's a compiz bug.
I followed https://wiki.ubuntu.com/DebuggingCompiz. There they say to install compiz-core-dbgsym compiz-plugins-dbgsym compiz-fusion-plugins-main-dbgsym compiz-fusion-plugins-extra-dbgsym compizconfig-backend-gconf-dbgsym libcompizconfig0-dbgsym compiz-gnome-dbgsym after adding the debug debs deb http://ddebs.ubuntu.com vivid main restricted universe multiverse deb http://ddebs.ubuntu.com vivid-updates main restricted universe multiverse deb http://ddebs.ubuntu.com vivid-proposed main restricted universe multiverse and running apt-get update. ;-) But there are not any compiz-dbgsym in the repositories. any idea? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1470097 Title: Unity does not support cpus without sse4 To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1470097/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
