Comparing behaviour in Lubuntu with behaviour in Ubuntu that has had LXDE added to it later is probably worth doing. I *think* this issue only happens in the Ubuntu-with-LXDE situation, not if you install Lubuntu.
(Total guess: could lxpanelctl be assuming that the root window it sends messages to is created by some part of LXDE which knows about lxpanel? And perhaps in the "Ubuntu-upgraded" situation, that root window actually belongs to/is created by some other app which has no knowledge of lxpanel, so it does not know what to do with the message, and so discards it?). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/769644 Title: Alt-F2 (or "lxpanelctl run") doesn't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxpanel/+bug/769644/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
