I've been having the same problem since upgrading via update-manager -d to Lucid yesterday, on an HP Compaq 6510b, which is a Centrino Duo.
$ apt-cache policy libindicator0 libindicator0: Installed: 0.3.4-0ubuntu1 Candidate: 0.3.4-0ubuntu1 Version table: *** 0.3.4-0ubuntu1 0 500 http://mirrors.rit.edu lucid/main Packages 100 /var/lib/dpkg/status $ uname -a Linux [hostname] 2.6.32-15-generic #22-Ubuntu SMP Tue Mar 2 02:24:17 UTC 2010 i686 GNU/Linux I have the battery set to always display, and this does slow its leftward march, but only as long as it's plugged in. As soon as you unplug it, it disappears/reappears about every thirty seconds (probably how often it's polling acpi for the battery state). My console is also being spammed with this every time it happens: (gnome-power-manager:4141): GLib-GObject-WARNING **: invalid cast from `GtkStatusIcon' to `GtkWidget' (gnome-power-manager:4141): Gtk-CRITICAL **: gtk_widget_hide: assertion `GTK_IS_WIDGET (widget)' failed -- battery applet comes and goes in notification area https://bugs.launchpad.net/bugs/529052 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
