Last update for now: I looked at the running processes while Ubiquity was on and found that "ps -A | grep xf" returned that xfsettingsd was marked as <defunct>.
So either the patch works and my testing borked the VBox or there's a problem with xfsettingsd not working as it should and therefore not providing the infos needed. (The icon-theme "elementary-xfce-dark" also isn't used in Ubiquity as far as I can see.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1010487 Title: Xubuntu - black windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1010487/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
