I've noticed the same bug. The keyword seems to be saved sessions. When SaveOnExit=true and AutoSave=true in ~/.config/xfce4-session/xfce4-session.rc , compiz isn't started when logging out and back in. xfwm4 isn't started either.
When SaveOnExit=false and AutoSave=false in ~/.config/xfce4-session/xfce4-session.rc and ~/.cache/session is cleared, everything works as it should. Besides, I don't see the difference between SaveOnExit and AutoSave. Autosave is changed when changing the option in Settings Manager->Sessions and startup, while it seems to change the value of SaveOnExit when logging out. -- compiz wont start by default on xubuntu startup https://bugs.launchpad.net/bugs/199705 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
