Also affected with a Core i7, an SSD and an Nvidia GeForce GTS 450 (proprietary driver). The workaround in comment #68 (sleep) fixes it for me too. Here's two lines from .xsession-errors when it doesn't work (with the workaround, these lines do not appear):
** (gnome-settings-daemon:1641): WARNING **: You can only run one xsettings manager at a time; exiting ** (gnome-settings-daemon:1641): WARNING **: Unable to start xsettings manager: Could not initialize xsettings manager. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/649809 Title: Meerkat (10.10) does not apply theme properly -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
