Symptoms summary:
After a recent(ish) update, I’m experiencing some weird issues with my KDE taskbar. So far, the problems I’ve identified are:
- Open programs/windows are not showing
- Pinned applications/shortcuts are not present
- The widget for switching virtual desktops is missing.
- While it’s unrelated to the topic, I noticed while writing this post that
spectacleis no longer working. I can’t take a screenshot, because the app opens but doesn’t display or capture any desktop image.
Background:
This started after updates I installed this past weekend. Unfortunately, I’ve been lazy and hadn’t installed updates for a couple months, so I’m not sure exactly which batch of updates were responsible. That said, I definitely experienced issues with the DBus transition. Immediately after the update, I was unable to log in to my computer after a reboot, because after entering my password, KDE would try to start, then hit a black screen and return me to the login prompt. I solved this by removing dbus-broker-units and reinstalling dbus-daemon-units. I also noticed some severe lag during system startup after resolving that, however it seems to have resolved itself after I did my best to ensure broker-related stuff was cleaned up.
Things I’ve tried:
- I’ve removed
.config, by renaming it to.config.bak. - I’ve reset the global theme back to default using the “Defaults” button under Appearance > Global Theme.
- I’ve run
kbuildsycoca5 --noincremental - I’ve created a new user and logged in to see if the issue is present there: It IS PRESENT for the new user, too.
