I then switched to another user (without logging out of the first account), and now notify-osd has two processes, one for each user and none for root. The notification is appearing correctly for screen brightness now (ie only one appears).
So it does seem likely that the root process is causing the second window. But why would there been a root notify-osd process? In case it's relevant, I rebooted recently (this morning) with an external monitor attached (which isn't attached any more; but I've restarted X since then although I haven't rebooted linux), and I've done 'sudo -s' in gnome- terminal to get a root prompt. -- notify-osd shows double image for screen brightness control https://bugs.launchpad.net/bugs/345251 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
