Thanks for your report! Yes, it doesn't seem to honor the "Show icon on system tray" setting at login. Can't tell ATM if ibus or KDE is responsible for that.
With that said, and considering that you prefer it to not be shown, I can't help suspecting that ibus is running unnecessarily on your system. Up to 20.04 ibus was installed for everyone on Kubuntu but only started by default if the language was Chinese, Japanese, Korean or Vietnamese. >From 20.10 ibus is not installed for everyone, but if you install it it's started automatically. The idea is that if ibus is installed it's assumed that you want to use it. (This can be controlled via the "Input Method Configuration" GUI.) So unless you use some IBus input method, the natural solution to fix it for you may be to simply uninstall ibus. Please clarify your actual use case. ** Changed in: ibus (Ubuntu) Status: New => Incomplete -- 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/1930145 Title: IBus Panel Show Icon on system tray doesn't persist Status in ibus package in Ubuntu: Incomplete Bug description: After a reboot in Kubuntu 21.04 (and 20.10) the IBus Panel icon appears in the system tray despite "Show icon on system tray" NOT being checked. Right clicking on the IBus Panel icon, checking "Show icon on system tray" and then unchecking again it causes the icon to be correctly hidden. But the problem reappears after the next reboot. Another user reporting what is almost certainly the same behavior: https://www.reddit.com/r/kde/comments/j91t8f/ibus_panel_icon_in_system_tray/ And this is an _identical_ bug report from 2012, so maybe it's a regression of some sort? https://bugzilla.redhat.com/show_bug.cgi?id=877135 Based om the trouble shooting requested at that time I get: $ gconftool-2 --get /desktop/ibus/panel/show_icon_on_systray No value set for `/desktop/ibus/panel/show_icon_on_systray' Note that I am running KDE, in case that's the important detail. The primary problem is that if you click on it accidentally and close the panel, you lose all keyboard input. $ lsb_release -rd Description: Ubuntu 21.04 Release: 21.04 $ apt-cache policy ibus ibus: Installed: 1.5.24-1 Candidate: 1.5.24-1 Version table: *** 1.5.24-1 500 500 http://us.archive.ubuntu.com/ubuntu hirsute/main amd64 Packages 100 /var/lib/dpkg/status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ibus/+bug/1930145/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
