Just in case anyone else hits this problem, I found the cause. My ~/.local/share/applications/ directory had a compiz.desktop file in it.
Don't know what wrote the file or tried to figure out exactly what in the file caused my "Visual Effects" settings to get messed up on login, but my other systems don't have this file and I simply renamed it to get rid of the problem. -- Appearance "Visual Effects" settings lost across reboots and log out / log on https://bugs.launchpad.net/bugs/500570 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
