Until then, the solution is to install some missing dependencies: use synaptic or whatever, and make sure you have all these installed, then, log out and back in: libappindicator1 python-appindicator python-gconf python-glade2 python-pexpect -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ibus in Ubuntu. https://bugs.launchpad.net/bugs/1078002 Title: "When active" setting does not work in Lubuntu. Status in “ibus” package in Ubuntu: Confirmed Bug description: "When active" setting in "IBus Preferences" --> "Show language panel" does not work - the language panel is not shown when Input Method is active. The only setting that works is "Always", which is very inconvenient - the panel is shown always, even when playing fullscreen video, viewing photos etc. This bug appears only in Lubuntu, in usual Ubuntu this setting works OK.
